Hi, I haven't used the tools for a while, but when I use an old file I get this error that is solved by putting the 2 .param, what is the reason? Should I do this now?

If

mc_mm_switch

was not defined, then you did not select a process corner using

.lib

, which is the preferred way since it automatically includes all of the model files. The set of models is spread over many files in a complicated way, and figuring out what files to include in what order is not easy to figure out.

.lib

does all that for you.

Yes I used a file that before it worked
