Description

If I use automatic macro placement, flow failed during PDN stage with following error.

[WARNING PDN-0234] spm_inst_0 has not been placed and fixed.
[WARNING PDN-0234] spm_inst_1 has not been placed and fixed.
[ERROR PDN-0235] Design has unplaced macros.

Expected Behavior

Complete PDN stage with automatic macro placement.
