Hi,
I am trying to compile the Open Cell Nangate45 Library with the Synopsys Library Compiler. By searching how to do this I came across the instruction from **broken link removed**. According to this it should basically work like this:
1. Starting Synopsys Library Compiler
2. Within Library Compiler read .lib file and write as .db file
However, if I try this with the unmodified NangateOpenCellLibrary_functional.lib (from the PDKv1_3) I get the errors and warnings you can see below. Does somebody has an idea what could be the problem and how to solve this?
Best regards,
Thomas
