about CDF parameters...

tkhan

Here's my situation: Say I make a schematic of an inverter, and the W and L are pPar() parameters so I can define them when the symbol is added to another schematic. Now I make a schematic with 3 inverter symbols all of different W and L, and I make corresponding layout - how can I do LVS in this case since the W and L are parameters? I found that for a single symbol and its corresponding layout, I could change the Base CDF parameters to match the W and L of the layout, but when there are 3 instances that way doesn't make sense. Any suggestions, if this is even possible?

I'm working with an old PDK which only has Diva rules.

  •  Thanks Andrew, you were right I just ran an LVS with 3 different inverters and it passed without modifying the Base CDF parameters. As you mentioned I did have to change it for a single instance when I tried a few days back, and I was curious how it would work in the case of multiple instances with different sizes.
