@Mitch Bailey @mehdi, Hi Mitch, when I do a top_level lvs check, I meet some problems, how can I solve them？ Attach my lvs rpt. And by the way, how can I just check the top-level lvs for my gds?

can you explain the problems?

My GDS has more net than the spice file.

@Jianwei Jia: If you want to compare at the top level, you still need to create "black box" entries for the subcells so that netgen knows what the subcircuit pins are and what order they're in. The "black box" entries need only the ".subckt ..." and ".ends" lines for each cell, and no contents.

Thank you Tim! I have another question is about the caravel, Should I checkout to this branch manually? After I make install, my caravel don't have any branch.

It should be

mpw6

, but you need to check what was the last tag that Jeff DiCorpo specified for MPW-six projects.
