LVS: Calibre Missing Instance

wgtkan over 6 years ago

Hello,

I am using Calibre LVS v2018.4_34.26.

When running calibere LVS I get LVS Discrepancy: Missing Instance error.

I generated layout using connectivity > generate all from source option.

I am using the ndiff resistors in my design. The resistors both in the schematic and layout are connected to the same nets. But when looking at the LVS report, it says “missing instance” because the two resistors are not the same name. I don’t know how this happened. I tried to change the name of the resistors manually, but this couldn’t fix the problem.

Cadence Virtuoso Version IC6.1.8-64b.500.1

Thank you so much for your help with this issue.

Calibre is a tool from Mentor Siemens. It is not a Cadence tool. So this is really not the best place to ask a question about Mentor tools - perhaps they have a community forum (certainly they have a support channel)?

Regards,

Andrew

Hello Andrew,

I figured it out. I should have done a cdl trigger execution.

Thanks a lot.
