I recently figured out how to enable strokes in Virtuoso, and was wondering if there is a Skill function that will descend into a block that a given set of coordinates is contained within? I searched the Skill help manual for "descend", but couldn't find any functions that do what I am describing. How can I descend into a block using a downward mouse stroke whose endpoint is inside the block?
Also, is it possible to define new strokes?
You would need a series of commands to do what you want, one of the edit in place commands (possibly leHiEditInPlace) but first you must enter the last stroke point before executing the command:
preXY( hiGetStrokeLastPt()) leHiEditInPlace()
Look in dfII/etc/sted for more info on how to set up the procedures to be called by the strokes.
The stroke editor - sted - is supported on Solaris but not on Linux in IC6.1. Start sted in a shell window to define your own strokes.
In reply to Austin CAD Guy:
I am very new to Skill coding. I understand that the hiGetStrokeLastPt() function is returning the endpoint of the mouse stroke, but what exactly is the preXY function doing?
In reply to MOSFET:
preXY is a method to cache a point to feed the next command. This usually eliminates the prompting for an additional point. It should work with the HI version of the command.
So the steps would be as follows:
1. save the coordinates of the endpoint of the mouse stroke using preXY(hiGetStrokeLastPt())
2. use a function to select the instance that contains the point saved in step 1.
3. use leHiEditInPlace() to descend into the instance selected in step 2.
What function will accomplish step 2?
No need for function for step 2. leHiEditInPlace will automatically select the cell under the point and pushes into it. See the help file on leHiEditInPlace to determine how it calculates which cell to choose based on overlapping shapes.
Is there a function like leHiEditInPlace() for schematics that will let me descend into a schematic block?
According to cdsFinder and the documentation, use schHiEditInPlace.
There is schHiDescend([w_windowid]) which will invoke the descend in the current mode (read/edit), or you can force the mode using either schHiDescendEdit() or schHiDescendRead()
Hope this is what you are looking for.
In reply to skillUser:
Thanks for the help. This code seems to accomplish my goal. A downward stroke into a block will descend into it, and an upward stroke will return one level up the hierarchy. The schHiDescend() function is what I was looking for, as opposed to the schHiEditInPlace() function.
firstPt = hiGetStrokeFirstPt()lastPt = hiGetStrokeLastPt() firstPt_yCoord = (cadr firstPt)lastPt_yCoord = (cadr lastPt) (cond ((lastPt_yCoord > firstPt_yCoord) schReturn())((lastPt_yCoord < firstPt_yCoord) preXY(lastPt) schHiDescend())(else (printf "Error determining direction of stroke\n")))
EDIT: It appears that schReturn() is not a valid function, even though leReturn() is a valid function. It also appears that leReturn() also works in schematics. Is there an equivalent leReturn() function for schematics, or should I just use the leReturn() function?

We are using IC188.8.131.520.12 on linux, but we also have available Solaris machines to log into. If I am logged in to a Solaris machine, can I run the sted program, even though the other Cadence tools we have are for Linux? Where exactly is the sted executable located?
First, I'm glad to see you are on IC6.1.
Set your path to the software on Solaris, it can be IC5141 or an older software as the strokes editor has not changed. It is in the <CDS_INST_DIR>/tools/bin directory - in my case /net/redneck/cds/sun4v/IC5141USR6/tools/bin. The resulting file (your def.strokes file) and other SKILL necessary to support the strokes should be in your home directory or your .cadence directory. Your .cdsinit should load it from where ever it is.

I think I found the sted executable here:
However, when I run "./sted", I receive the following error:
"Can't initialize the selected window system".
I am using rsh to connect to the Solaris machine from my Linux machine. What do I need to do to run sted?
I would suspect that the rsh window does not have the display properly set. Use the command: echo $DISPLAY to show the display and make sure it is set to your system display. Rsh usually does not reset the display.
If this does not work, you need to run a thin client which uses the native Solaris windows system. Use VNC or some other Solaris based thin client to display back to your screen.

I did a "setenv DISPLAY <myIP>:0.0", and now when I run "./sted", it just says "Segmentation fault". How can I debug this?
I usually run VNC on my systems to handle the displays so is anyone who can answer the question:
How do I get a Solaris based tool to display on a Linux box?
