LVS Operation suddenly broke

Kabal

I have several previously submitted (and even tested) and successfully DRC'ed/LVS'ed designs of some amplifiers etc. Now I want to perform LVS again since I want to start another design based on old one, and suddenly LVS exists with these errors:


*ERROR* cell 'ind' is not defined.
*ERROR* cell 'pcdcap' is not defined.
*ERROR* cell 'bondpad' is not defined.

I have no idea what could go wrong? Same layout was LVS'ed nicely before with inductors and with above mentioned devices.

Any ideas what exactly could break suddenly?

  • Thanks for reply,

    1) Yes, I am using Assura LVS.
    2) I am not doing blackbox LVS, I just have custom schematics with transistors and other different elements, then I export the netlist, then I pass it through the LVS script as always and export to final netlist for LVS in CDL format.

    Always been doing it and it worked, but now it does not. The funny thing is, when I try to LVS one of the inverters I have with just two transistors, it is OK. But when I try to LVS something with inductors, bondpads, caps etc.. it gives errors like I shown.

    And again, all circuits worked before, and were even manufactured and tested. Not sure what on earth could go wrong there?
