Extracting LEF Hierarchically in Innovus

Alen Duvnjak

Hello,

I am currently using Innovus to build a hierarchical design where the levels of hierarchy can range from 2 to 6/7. I'm having some issues right now getting the -extractBlockObs flag to work for the write_lef_abstract command. It does not seem to want to pull the obstruction information from my lower level LEF(s). I verified that they are marked as CLASS BLOCK. Any suggestions?

Also, on a side note, is there any way for write_lef_abstract to extract VIA information? This would be extremely useful in my current flow, but I have been unable to get this to work as of now.
