I want to check BGA minimum pitch. If BGA pitch is less than 0.5mm, need to highlight these BGA in PCB layout. Does anyone have experience to write script to do the check?

Shape Degassing parameters extraction using SKILL in allegro APD

AnanthVedalaLM — Wed, 08 Jul 2026 23:02:08 GMT

I'm trying to extract the values set for a specific degassing pattern using skill , but instead of name , i'm unable to get anything else , is there any way we can extract the void array parameters and void spacing constraints that we set in the shape degassing tool, instead of using GUI, is there any other option to set those parameters for a pattern and also extract them

usually i'm getting the pattern name in this way

shapedbId->shapeBoundary->prop->DEGAS_SHAPE_PROPERTIES

which just leaves me with the name of the pattern used on the shape, but unable to figure out how do we actually get these parameters using skill

other questions i have ,

Are these parameters for the dynamic shapes global or local ? and how are these parameters stored in the database

axlOpenDesignForBatch( works differently between 22.1 and 25.1 ( appears broken )

Mhawley1 — Tue, 07 Jul 2026 13:05:43 GMT

I just found something interesting today and would be nice for someone to test.

It would seem like axlOpenDesignForBatch( no longer runs without a save prompt in 25.1 under the WF mode . Can someone try this out . Try out the example and see if you can batch open two dra's without the prompt coming up .

axlOpenDesignForBatch("u.dra" "wf") ( tested in 25.1 S 30 )

Should I make a ticket ?

How to import a techfile through SKILL

JuanCR — Thu, 02 Jul 2026 12:30:33 GMT

axlRunBatchDBProgram can be used to import a techfile.

Open the design in Allegro X PCB Editor or Package Designer and type skill at the command line:

Command > skill

The command line changes to the Skill prompt:

Skill >

The following skill code will create a log file and import a techfile. In the following skill code, replace mytechfile.tcfx with your own techfile name including the .tcfx extension:

Skill > axlRunBatchDBProgram("techfile" "techfile -$ -r mytechfile.tcfx %s" ?reloadDB t ?logfile "techfile")

Wait while the techfile (apd) runs:

The view of the techfile UI will appear. Scroll to view the summary.
Close the file.
In the database, to exit from the skill prompt, type exit:

Skill > exit

The Command window changes from Skill > to Command >:

Command >

axlDesignFlip()

DavidAhl — Fri, 26 Jun 2026 10:06:26 GMT

Hi,

Im using the axlDesignFlip() in a script. In version 23.1 it worked great but when i run the script in version 25.1 it wont flip back the design. From the documentation i cant see that anything has changed. Is this a known bug in 25.1 or have i missed if something changed?

I tried this in both 23.1 and 25.1, both gave the same print out but in 25.1 the design doesnt flip back..

best regards

david

How to start SKILL IDE from APD or Allegro in Linux?

JuanCR — Fri, 05 Jun 2026 23:35:51 GMT

The debugger environment is not so convenient for APD / Allegro debug. It is more oriented for SKILL DFII development. SKILL Debugger is incapable to debug the axlSKILL (Allegro specific) functions.

There is no graphical debugger for axlSKILL, but you can set the telskill environment variable to open a SKILL development window.

If you are looking for line debugger with Allegro, there are some command line debugging options available to you:

installDebugger() and axlDebug() are functions you can use to set debug mode.

The following is an extract from the axlIsDebug() function description in cdnshelp, which describes what axlDebug enables:

When this mode is set, AXL may print additional AXL API argument warnings when arguments to AXL functions are incorrect. Many warnings do not obey this variable because they are considered serious or edge conditions. Warnings supported are less serious and are known from user feedback to be troublesome to program around.

Typically, when an AXL API function encounters an argument error, it will print a warning and return nil.
When unset, the code runs in development mode and eliminates many of these warnings. You should have this mode enabled when developing SKILL code.

Another function available to you is sstatus. Refer to the online documentation to get the full list of the internal variable names and switch values available to you through this command.

sstatus(
s_name
g_switchValue
)
=> g_switchValue

Description: Sets the internal system variable named to a given value. This is a syntax form. Internal variables are typically Boolean switches that accept only the Boolean values of t and nil. Efficiency and security are the reasons why these system variables are stored as internal variables, which can only be set by sstatus, rather than as SKILL variables you can set directly.

Other things you can do are set breakpoints with breakpt and then progress through your code with step and continue etc.

Note: The online document, SKILL Development Functions Reference, is helpful for describing the functions. However, you must be aware that any reference to a graphical interface for debugging does not apply to axlSKILL. As with any programming language, you can set a debug variable and then make conditional checks for it. If set, you can have your code print values of variables from your code.

The other way to check the code before delivery is to launch the SKLINT tool and to try to solve all warnings, errors given by this tool.

Steps to use SKLINT on UNIX:

Run setenv TELSKILL in your local env file.
Run Allegro and then keep Allegro iconified.
In the current shell window, the prompt becomes SKILL>. Launch SKILL> sklint ?file "filetodebug.il".
filetodebug.il is the file name you want to debug.

How to use Stack in Allegro SKILL

JuanCR — Thu, 16 Apr 2026 21:46:08 GMT

Stack is a popular data structure in programming languages. It is like a real-world stack such as piles of papers, where papers are usually added to the top of the pile and removed from the top. So, in a stack data structure, you can add or remove elements from the top of the stack using the LIFO (Last-In-First-Out) principle.

Stack in Allegro SKILL is a list that works like a stack using APIs/functions pushf and popf.

pushf adds an element to the top of the stack, that is, adds the first element to the list.
popf removes an element from the top of the stack, that is, the first element of the list.

The code is as shown below:

myStack=list(3 4 5 6)
printf("Stack is %L\n" myStack)
pushf(2 myStack)
printf("After pushing 2 Stack is %L\n" myStack)
pushf(1 myStack)
printf("After pushing 1 Stack is %L\n" myStack)

printf("Before popping Stack is %L\n" myStack)
elem=popf(myStack)
printf("After popping: Element removed from stack is %L and Stack is %L\n" elem myStack)
elem=popf(myStack)
printf("After popping again: Element removed from stack is %L and Stack is %L\n" elem myStack)

The following image shows its output:

Interactive Form

AA202603241137 — Wed, 25 Mar 2026 07:20:07 GMT

I am planning to create a script but this needs to have a form that is interactive. The form changes depend on the number of layers in the PCB. My idea to list all the layers of the PCB in the form and also have a checkbox beside each layer name. But my knowledge on the form is basic only. I only use TEXT, GROUP, MENUBOTTON, STRFILLIN. Can somebody guide or educate me. Thank you.

How to use regular expressions in SKILL

SaiPavanl — Fri, 20 Feb 2026 07:55:52 GMT

Often, you need to match strings or symbols against a pattern. A regular expression is an object that describes a pattern of characters. Regular expressions are a way to match patterns with sequences of characters. They are used in every programming language like C++, Java, and Python. SKILL also provides a number of pattern-matching functions like rexMatchp, rexCompile, and rexExecute.

SKILL also supports pcreCompile and pcreExecute for Perl-Compatible Regular Expressions (PCRE).

rexMatchp

If you want to see whether the string matches a regular expression, you can use rexMatchp. For example, to check if a string has only numbers with a decimal point, you can use rexMatchp, as shown below:

Rules for constructing patterns or regular expressions are given later in this article.

Note: Here, the output of the SKILL command is shown after the => symbol:

rexMatchp("[0-9]*[.][0-9][0-9]*" "100.001") => t

rexMatchp("[0-9]*[.][0-9]+" ".001") => t

rexMatchp("[0-9]*[.][0-9]+" ".") => nil

rexMatchp("[0-9]*[.][0-9][0-9]*" "10." => nil

rexMatchp("[0-9" "100")

*Error* rexMatchp: Missing ] - "[0-9"

rexMatchp( t_pattern S_target )

This function matches S_target against the t_pattern regular expression and returns t if a match is found; otherwise, it returns nil.

An error occurs if the given pattern is ill-formed.

rexCompile and rexExecute

For greater efficiency when matching a number of targets against a single pattern, use the rexCompile and rexExecute functions. For example, if you need to work on nets that match a pattern, use rexCompile and rexExecute instead of using rexMatchp.

rexExecute matches a string or symbol against the previously compiled pattern that was set up by the last rexCompile call.

To check if the name of the nets that can be alphanumeric begins with alphabets, use the following command:

rexCompile("^[a-zA-Z][a-zA-Z0-9]*") => t

rexExecute('Net123) => t

rexExecute("123 Nets") => nil

Note: Calls to rexMatchp reset the pattern set up by rexCompile. If any calls to rexMatchP have been made, rexExecute will not match the pattern set by rexCompile.

PCRE

The PCRE library provides functions for pattern matching using Perl-compatible regular expressions. For more details, refer to https://www.pcre.org.

pcreCompile compiles a regular expression string pattern(t_pattern) into an internal representation that you can use in a pcreExecute function call. The compilation method is PCRE or Perl-compatible. You can use a second (optional) argument to specify independent option bits for controlling the pattern compilation.

pcreCompile(

t_pattern

[ x_options ]

)

=> o_comPatObj / nil

For example, the [12[:^digit:]] PCRE pattern matches 1, 2, or any non-digit.

comPat1 = pcreCompile( "[12[:^digit:]]" ) => pcreobj@0x27d150 (Note that your object will be different)

pcreExecute( comPat1 "abc" ) => t

pcreExecute( comPat1 "12a") =>t

pcreExecute( comPat1 "3") =>nil

Here is another example:

comPat5 = pcreCompile( "^\\d?\\d(jan|feb|mar|apr|may|jun)\\d\\d$/" )

pcreExecute( comPat5 "25jun3" ) => nil

pcreExecute( comPat5 "25jun3" pcreGenExecOptBits(?anchored t) ) => nil

pcreExecute( comPat5 "25jun3" pcreGenExecOptBits(?partial t) ) => t

Rules for constructing pattern or regular expressions

Regular expressions can contain both special and ordinary characters. Most ordinary characters, like 'A', 'a', or '0', are the simplest regular expressions; they simply match themselves. You can concatenate ordinary characters, so that last matches the 'last' string. There are also special symbols like *, +, and so on, which you can see in detail here:

\ General escape character with several uses

^ Assert start of the string (or line, in multi-line mode)

$ Assert end of the string (or line, in multi-line mode)

. Match any character except new line (by default)

[ Start character class definition

| Start of alternative branch

( Start subpattern

) End subpattern

? Matches 0 or 1 quantifier

* Matches 0 or more

+ Matches 1 or more

The part of a pattern that is in square brackets is called a "character class". In a character class, the only metacharacters are:

\ General escape character

^ Negates the class, but only if the first character

- Indicates character range

[ POSIX character class (only if followed by POSIX syntax)

] Terminates the character class

Asterisk symbol (*)

While matching, it checks if the preceding character (or set of characters) repeats for 0 or more times (up to infinite).
Example: The ab*c regular expression matches with ac, abc, abbc, abbbc, and so on.

Plus symbol (+)

While matching, it checks if the preceding character (or set of characters) repeats for at least one or more times (up to infinite).
Example: The ab+c regular expression matches with abc, abbc, abbbc, and so on.

Wildcard (.)

The dot symbol can match any character; hence. it is called the wildcard character.
Example: The .* regular expression matches with any character any number of times.

Optional character (?)

While matching, the preceding character may or may not be present in the string to be matched.
Example: In docx?, the ? character tells the computer that x may or may not be present in the name of file format.

Caret symbol (^)

The match must start at the beginning of the string or line.
Example: ^abc matches abcd but not zabc.

Dollar symbol ($)

The match must occur at the end of the string or before \n at the end of the line or string.
Example: 333$ matches 901-333 but not 333-901

What do you know about RAVEL versus SKILL ?

John T — Tue, 10 Feb 2026 17:30:25 GMT

Show what you know! Can you answer these quick fire questions:

True or False: RAVEL is “declarative” while SKILL is “procedural/functional”?

True or False: RAVEL violations can be cross‑probed in the layout via the DRC Browser?

Choose the best option, “when to use”:
A. SKILL to create new database objects; RAVEL to check rules/flag violations
B. RAVEL to create symbols; SKILL to list DRCs
C. SKILL only for DFM checks; RAVEL only for routing
D. They’re interchangeable

How to run batch IDX files

Mhawley1 — Mon, 09 Feb 2026 16:21:14 GMT

Has anybody sucessfully exported a IDX file using the external EXE that came with the install . -> see the code below which ,... doesnt work .

file_name = axlCurrentDesign()
whole_board_name = strcat(file_name ".brd")
working_directory = getWorkingDir()
all_of_it = strcat(working_directory "/" whole_board_name)
whole_idx_command = strcat(all_of_it -o base ")

exe_path = "C:/Cadence/SPB_22.1/tools/bin/idx_out.exe"
;C:\Cadence\SPB_22.1\tools\bin so this is where that idx_out.exe is .

; so its not a shell command its a exe command you need to do .

axlRunBatchDBProgram(exe_path whole_idx_command)

; so this doesnt work .

digital1 — Sun, 08 Feb 2026 12:31:44 GMT

Hi i have created a routine in skill to run in pcb editor this code runs and does its thing however i now want to code a menu so the menu is inserted at startup.

i have inserted the file to load in my allegro.ilinit as (load "net_short.il")

the top of my net_short.il file is

q = axlUIMenuFind(nil -1)
z = axlUIMenuInsert( q 'popup "TDR Electronics")
axlUIMenuInsert(z "Net Short" "net_short")

axlCmdRegister("net_short" `_net_short)

however there is no menu at the top of the pcb editor and it should be left of the help menu the code has been loaded because when i type net_short in the command window the code runs

however i can type in the command window skill load "net_short.il" and the menu has my updated menu in it and i can then run the code from that menu.

I believe it is a timing issue but i dont know how to get any further I am running orcad pcb version 24.1

can any one help

Issue with function @key parameters

DavidJHutchins — Tue, 04 Nov 2025 18:00:33 GMT

I have noticed an issue with @key parameter default values not getting processed correctly...

Below is an example code segment:

procedure( test_code(
@key ( PseudoName "psuedo_tp")
( PreFix "_TP")
( Debug t)
)
let((Mark PreFix Comps net count Status)
when(Debug printf("PseudoName %A PreFix %A Debug %A\n" PseudoName PreFix Debug))
;; initialize variables
(count = 0)
unless(stringp(PseudoName) (PseudoName = "PSUEDO_TP"))
unless(stringp(PreFix) (PreFix = "_TP"))
when(Debug printf("PseudoName %A PreFix %A Debug %A\n" PseudoName PreFix Debug))
)
)

When I run this is Allegro, the Prefix parameter default value of "_TP" is discarded, as shown below:

\i (00:00:47) skill test_code
(00:00:47) PseudoName "psuedo_tp" PreFix nil Debug t
(00:00:47) PseudoName "psuedo_tp" PreFix "_TP" Debug t
(00:00:47) t

Has anyone else seen this issue? if so, what is the solution...

How can I encrypt a SKILL file for Allegro products?

SaiPavanl — Wed, 22 Oct 2025 07:29:48 GMT

The SKILL files of Allegro X PCB Editor, Allegro X Advanced Package Designer, Allegro Design Entry HDL can be encrypted. Encrypted files are used to conceal the file contents. The *.eil and *.ile file extensions are used for encrypted SKILL files.

To encrypt a SKILL file on Windows, perform the following steps:

Open the command prompt.
Use the cd command to move to the folder where the SKILL file is stored.
Type cdsmps and press the Enter key.
The prompt will change to ">". Here, type the following command to encrypt the SKILL file:

encrypt( "input_filename" "output_filename" "password")

Where,
input_filename: The ASCII SKILL file. The extension for the file is .il.
output_filename: The name of the encrypted file. The extensions allowed are .il, .ile, and .eil. However, because the non-encrypted SKILL files have the extension .il, it is recommended that you avoid using this extension for encrypted files. Use .ile or .eil instead.
password: The password needed to load the encrypted file. The password is optional.

The example shown in the following image encrypts a SKILL file without a password:

The following image shows another example in which the SKILL file is encrypted with a password:

Loading a SKILL file

Use the following syntax to load an encrypted SKILL file without a password:

load("filename")

Where,
filename: The encrypted SKILL file name

The following example shows how to load an encrypted SKILL file without a password:

Skill > load("./test_npwd.eil")

To load an encrypted SKILL file with a password, use the following syntax:

load("filename" "password")

Where,
filename: The encrypted SKILL file name
password: The password supplied when encrypting the SKILL file

Here is an example of how to load an encrypted SKILL file with a password:

Skill > load("./test_en.eil" "cadence")

Encrypting a SKILL file on Linux

To encrypt a SKILL file on Linux, use the following command:

encrypt( "input_filename" "output_filename" "password")

You encrypt a SKILL file when you do not want users to see the IP contained in the file or modify the program. Encrypted SKILL files can be loaded using the load command, but they CANNOT be de-encrypted.

Creating custom toolbar manu item on program startup

UsableLoki — Tue, 16 Sep 2025 16:04:58 GMT

I have a program that will create a custom menu toolbar item along with its submenu items. I tried to run this procedure that creates them on startup by placing the run function inside C:\SPB_Data\pcbenv\allegro.ilinit. Through the console I can confirm that my function properly ran and is loaded, but the menu toolbar does not have my custom item. If I rerun the function my menu toolbar will finally be created. I know this can be done as there is another function that we contracted Cadence to build which is also called in the allegro.ilinit, however the file called is encrypted so I can't see what was done that is different from my attempt. Any help would be great.

Below is relevant snippets of my code.

Content within the .ilinit-

fileLocation = "S:/.../GUI_Implementation.il"
if(isReadable(fileLocation)
then
load(fileLocation)
refresh_Menu()
else
printf("Error loading: %s\n" fileLocation)
)

file GUI_Implemenatation.il-

procedure(refresh_Menu()

axlUIMenuInsert(axlUIMenuFind(nil -1) 'popup "CUSTOM-SKILL")

)

How can I build a popup menu and add a separator line in Allegro SKILL?

JuanCR — Sun, 07 Sep 2025 23:45:22 GMT

This article focuses on a specific code snippet (provided below) that demonstrates adding a menu and separator using the Allegro SKILL program.

(procedure myShowElement ()

mypopup = axlUIPopupDefine(nil

(list (list "Done" 'axlFinishEnterFun)

(list "Cancel" 'axlCancelEnterFun)

(list "MENU_SEPARATOR" nil)

(list "Hello" 'hello))

)

axlUIPopupSet(mypopup)

axlSetFindFilter(?enabled list("NOALL" "ALLTYPES" "NAMEFORM") ?onButtons "ALLTYPES")

while(axlSelect()

axlShowObject(axlGetSelSet())

))

In Allegro SKILL, the axlUIPopupDefine() function is used to create and configure popup menus. It specifies name-value pairs to define the menu name and associated actions within the menu.

For example, the menu item “Done” is tied with the Allegro SKILL function “axlFinishEnterFun” and the menu name “Hello” with the user-defined procedure "hello", which prints “hello”.

mypopup = axlUIPopupDefine(nil

(list (list "Done" 'axlFinishEnterFun)

(list "Cancel" 'axlCancelEnterFun)

(list "MENU_SEPARATOR" nil)

(list "Hello" 'hello))

)

Action for the Menu items

The axlFinishEnterFun() function terminates the waiting process for a user-selected point. It returns either t or nil depending on the success or failure of the user selection. It is like clicking “Done”.

The axlCancelEnterFun() function serves a similar purpose to axlFinishEnterFun() in terminating the waiting process for a user-selected point. It functions as a cancelation action, like clicking the "Cancel" option.

(procedure hello()

printf("hello")

)

Showing the Context Menu

To make a specific popup menu active, the returned identifier from axlUIPopupDefine() is passed to the axlUIPopupSet() function. This ensures that the menu is displayed and ready for user interaction.

Adding a Separator in the Context-Sensitive Menu

A separator in GUI visually divides menu items and improves the overall readability and organization of the menu.

To add a separator to the popup menu, you must include a particular menu item called "MENU_SEPARATOR" in the list of menu items in the axlUIPopupDefine function, as shown below.

In the axlUIPopupDefine() function, a sublist is created with the label "MENU_SEPARATOR" and a `nil` value. This label is recognized to add a separator in the popup menu. The `nil` value is used as a placeholder since no action is associated with the separator.

mypopup = axlUIPopupDefine(nil

(list (list "Done" 'axlFinishEnterFun)

(list "Cancel" 'axlCancelEnterFun)

(list "MENU_SEPARATOR" nil)

(list "Hello" 'hello))

)

When the popup menu is displayed, Allegro SKILL interprets the "MENU_SEPARATOR" item and visually separates it from the other menu items with a horizontal line.

The provided code demonstrates creating the menu item and including a separator in a popup menu using the Allegro SKILL language. By understanding this concept, developers can enhance the user experience of their GUI applications by making menus more intuitive and visually appealing.

Trouble With Layer Name Pair

MarkGorecki — Wed, 27 Aug 2025 17:42:25 GMT

Hello,

I'm using Cadence Allegro 24.1 and I'm trying to check if the layer "Package_Top" is visible and if not, make it visible.

Neither of these commands work:

if(not(axlIsVisibleLayer("STACK-UP/PACKAGE_TOP")) then

if(not(axlIsVisibleLayer("NON-CONDUCTOR/PACKAGE_TOP")) then

I get this:

*WARNING* Layer does not exist: STACK-UP/PACKAGE_TOP

*WARNING* Layer does not exist: NON-CONDUCTOR/PACKAGE_TOP

If I use just "PACKAGE_TOP", then I get: *WARNING* Layer does not exist: PACKAGE_TOP

Does anyone know the layer pair, or just the layer name that I would use?

Thanks,

Mark
