Rename label and part of instance in multiple layouts

AnuJoamon

I have many layout cells in my library in which I need to do two changes

  1. I want to replace label xxxABxxx with xxxCDxxx (in a specific layer say "m1" "dg")
  2. Replace instance yyyAByyy from library YYYY to instance zzzCDzzz from library ZZZZ.
  3. Check that there is no instance in the entire library coming either from the same library of one reference library (specified).

Anuj.

     And a good opinion it is, Derek.

    The use of the if statement without a then or else is a common source of costly errors. I had a customer who modified such a statement by putting in a third statement which turns it from an if/then/else to an if/then. They were desparate as it was holding up a tapeout.

    After I found the problem and sent the fixed code and a very big bill, they complained that all I added was two words, then and else and should not pay hunderds of dollars for two words. The bill was sent back to them listing $.50 cents per word and the rest for the knowledge where to place them. They paid.
