I notice a number of these in an openlane run where I'm integrating macros:
Copy code
[WARNING ODB-0177] error: undefined via (via3_1600x480) referenced
It looks like it's caused by different settings for
FP_PDN_VWIDTH
and
FP_PDN_HWIDTH
in the macro and top level configs. I'll recreate my macros with the same PDN settings, but I was wondering how bad it is and if openlane should error out. I do see met4-met5 vias inside the macros in the final GDS.
