SKILL Variable

hrishikesh

I am new to Cadence SKILL. I am trying to understand a SKILL script file containing many procedures. Many of these procedures use a variable which holds a constant list. But it doesn't seem to be assigned anywhere in the script file. Can you suggest any possible place from where it could be assigned? Is there any way in SKILL to import variables from another file?

  • I'm having a similar problem, so I thought I'd add on to this thread. I have an existing library that I wanted to copy to a new library and change the reference libraries to the new library. I did this using the "copy wizard," and it seemed to work for the most part. However, I have SKILL scripts where I'm trying to create PCELLs in this new library, and I'm running into problems. 

     I am using an optional input parameter for my script called "dbDelta" which is set at the top of the script (before the "let" statement) using the following syntax: (dbDelta list(1.0 1.0))

     It was causing errors that it's never caused before, so I used the setguard() function mentioned above to see where this variable was being changed. The setguard() function told me:

    Variable dbDelta set to '('('('('((1.0 1.0)))))) in "(path of script I'm working with)" 

    It seems that the error is a result of copying the old library to a new library and using the "update instances" option in the "copy wizard". Nowhere in my script am I setting the value of dbDelta other than the top, and if I change the name of dbDelta to anything else, the problem goes away. Thoughts?
