Different wire load models are applied to the individual subblocks of a design that
correspond to the physical hierarchy. Low-level hierarchical blocks are often
“dissolved” into higher level blocks during floor planning. Use the following command
to set the wire table for a block:
> report_wire_tables -summary
> set wire_table cg61_5000area
