FYI, The problem is with having multiple power rails. The cells have VDD and VSS plus two other rails, which is specified in the liberty multi-rail format v2. Reverting to liberty multi-rail format v1 and removing the additional power rail definitions from the .lef makes Innovus recognize the cells. Even though this is the workaround I am using for the moment, I am still curious for a proper solution![]()
