But when using NangateOpenCellLibrary_PDKv1_3_v2010_12, I can not find that file. What should I select in this case? I have tried to use the following file:
Redeclaration error. So copy the older library to a lib file with a new name, then remove all the models which are already declared in the newer lib file, and again .INCLUDE both libs (the rest lib and the new one).
Or copy the newer lib to a lib file with a new name, and copy and paste the missing models from the older lib into this copied lib file. .INCLUDE just this one.
