A rather unconventional schematic symbol question/issue

Composter

 Hi,

 I'm using Cadence 5.1 and am trying to make some schematic symbols that display context dependent information when instantiated. Onthe symbol itself, I have several ILLabels such as "ilInst~>myvar" and I have edited the cdf such that "myvar" contains some skill code that evaluates to the string of what I want displayed on the symbol. I'm accessing the data about the selected instance through expressions like "cdfgData->width->value". Much of this is based on code I've seen used elsewhere and I've just adapted it to suit my needs.

 

So I'm running aground because I don't know how to access the instance name (as opposed tthe cell name) within an expression. I've already tried cdsName() but that does not return the current instance name of the selected instance. Can anybody out there please provide me with the skill magic to do this. I figure it has to be available via cdfgData but I don't the access name. Many thanks in advance.

  • Thanks for the explanation Ted. I didn't appreciate until now that cdfgData pointed to the master and not the instance. I have certainly noticed that cdsName() works for some of my symbols and not others. I've never played with CDS_NETLISTING_MODE so it's weird that cdsName() isn't behaving consistently for me. 

     By the way - your last name wouldn't happen to start with "P" would it :-)
