Hi,
I am using Innovus/Voltus/Tempus 21.10 but experiences a fatal error when loading the design finished by Innovus in Voltus or Tempus: (read_db -oa_lib_cell_view ; actually the first command in the init script )
**ERROR: (IMPESI-3490): cdB based analysis is not supported with CMMMC configuration. This may result in inaccurate analysis. Configure and run analysis in SMSC if using cdBs.
The tool self-closes.
The MMMC av definition includes library sets with -timing links to ecsm libraries as well as -si links to cdb libraries for signal integrity. The implementation flow with innovus runs succesfully but signoff tools complain about the cdb libraries. When I run implementation without cdb, it is loaded without errors in voltus/tempus.
Same issue with flowkit/flowtool when si_files are defined .
I'm using oa libraries throughout the entire flow. How should I load the oa library in voltus correctly and switch to SMSC? Or is the cdb based analysis deprecated?

Thanks a lot!
