Question

In netgen I see ```Circuit contains 102349 nets and 528 disconnected pins Circuit 1 contains 235574 devices Circuit 2 contains 235574 devices Circuit 1 contains 102330 nets Circuit 2 contains 102349 nets MISMATCH ``` What are these two circuits being compared

< Jean> What are the previous lines Maybe check results lvs lvs log

Jean · Answer

Portion of console log attached

Mitch Bailey · Answer

< Jean> It might be due to the disconnected pins messages Is it possible for you to upload the following 2 files to somewhere If you can I will take a quick look at it I ve been running LVS on the other caravel modules and the sample designs in openlane ```results magic sha3 256 miner spice results lvs sha3 256 miner lvs powered v```

Jean · Answer

Sorry these have already been blown away

Mitch Bailey · Answer

No problem If at anytime in the future you want me to take a look just let me know

tnt · Answer

Did you look at the actual report

tnt · Answer

It s `results lvs xlvs log` and is different from the console output it will show the net mismatches

tnt · Answer

In the console output you posted I don t really see anything suspicious placeholder message is just because it doesn t dig down inside the cells so they re created dynamically as blackboxes

tnt · Answer

Disconnected pins are not necessarely errors either sometimes not all pins are used on a cell module
