Extract information from pins of a certain spacing class property

mesaman000

Hi everyone,

    From my previous post I've found out how to color pads and vias of the certain spacing class that I'm looking for.  As the title states, now I'm trying to extract and print information from those nets to a report.  Basically I want to parse through all of the nets and filter out/select all of the pads/pins with that spacing class property which I do by using this code:

  axlClearObjectCustomColor(axlDBGetDesign() ->nets)

;Select all nets/pins

axlSetFindFilter( ?enabled (list "noall" "pins"  "invisible")  ?onButtons (list "pins"))

axlAddSelectAll()

pins = axlGetSelSet()

 

  

csetNets1 = axlSelectByProperty("net", "SPACING_CONSTRAINT_SET", "TYPE1")

;;Extract which nets have the spacing class property "TYPE1"

cset1_pins = setof(pin, pins, member(pin ->net, csetNets1))

 

 ...

etc. 

From there I want to  take csetx_pins and print them out to a report.. I want the report to look like this:

**********************

Report

**********************

 

CurrentTime : Mar 25 09:31:46 2013 

 

Pin name x coord        y coord Mirrored? Rotation            SPAC_CLASS PAD_NAME Net_name

==================================================================================================================================

Q7.2 58.5 23.0 NO  270 degrees TYPE1 SR061X046 CONT_+3.3V

C1807.2 26.0 23.0 NO  270 degrees TYPE1 SR110X100 CONT+5V

Q2.1  42.0 23.0 NO  270 degrees TYPE2 SO220X064 GND

 

Q3.2 58.5 23.0 YES  270 degrees TYPE1 SR061X046 CoNT_+3.3V

C17.2 26.0 23.0 YES  270 degrees TYPE2 SR110X100 CONT+5V

Q9.1  42.0 23.0 YES  270 degrees TYPE3  SO220X064 GND

 
As you can tell I'd like the report sorted by the mirrored property first to determine which pins are on the back of the board and the front of the board.  Then I'd like to sort the report by spacing class (TYPE1, TYPE2, TYPE3)
 
 

 Here's what I have so far:

===================================================================== 

 cl_file = outfile("net_list.rpt" "w")

; ------ Print Header 

fprintf(cl_file "**********************\n")

fprintf(cl_file "Report\n")

fprintf(cl_file "**********************\n\n")

; ------  Print CurrentTime

fprintf(cl_file "CurrentTime : %s \n" getCurrentTime())

 

; ------  Print column headers

fprintf(cl_file "Pin name \t x-coord \t y coord \t Mirrored? \t Rotation \t Spacing class \t Pad type \t Net name\n")

fprintf(cl_file 

"====================================================================================================================================\n")

design_dbid=axlDBGetDesign()

l_comp_dbids=design_dbid->components

 

foreach(comp_dbid l_comp_dbids

ref_des=comp_dbid->name

symbol_dbid=comp_dbid->symbol

xy_loc=symbol_dbid->xy

;pins= symbol_dbid->component->pins

mirrorstatus=symbol_dbid->mirrorType

rotationstatus=symbol_dbid->rotation

;padid=axlDBGetPad(symbol_dbid,"ETCH/TOP","REGULAR")

 

fprintf(cl_file "%s \t\t %L\t\t %s\t\t %4.0f degrees \n" ref_des xy_loc mirrorstatus rotationstatus)

)

close(cl_file)

 
Can anyone help guide me in a more efficient direction because it seems like this is not the most efficient method..
 
 
Thank you very much! 
  • From an efficiency standpoint look at the following:
    1. get all nets  axlDBGetDesign()->nets
    2. for a net, get all pins on the net use the API: axlPinsOfNet(net 'pin)
    3. cset assigned to net (this assumes you have a dbid of a net assigned to a variable "net")
    net->prop->SPACING_CONSTRAINT_SET

    You would need to do more work get to the spacing cset is assigned using groups (netclass, bus, diffpair, etc.) For example, you place the nets into NetClass' and then assign the spacing cset at the net class level. You can use

           axlNetClassGet(...)

    after step 2 and then get the  SPACING_CONSTRAINT_SET off of the netclass
