Hello everyone,
I am new to IC Compiler. I am seeking some help from all the experts over here
I have a question on reading DEF file generated after floorplanning with pads, unplaced cells.
Example DEF COMPONENT section:
- BLOCKA/AND_INST1 AND_SVT + UNPLACED;
When I execute read_def, I am getting the error:
Error: Cannot find hierarchical cell 'BLOCKA' in DEF component ''BLOCKA/AND_INST1' in current design.
I think the tool is trying to find BLOCKA data such as CEL and FRAM,
but is there a way to read the DEF as flat, instead of letting the tool think it needs that hierarchical data?
FYI, prior to read_def, I performed basic command such as setting search_path, link lib, target lib, create_mw_lib etc.
I did not set any specific command related to floorplanning.
Am I missing some commands that will help treat read_def as flat? Thank you.
Regards,
Victor

Hi,
FYI, in my flow, prior to read_def, I did not read in Verilog netlist. Is this needed?
I assume I don't need this because the DEF already has the cells. But I could be wrong.
Thank you,
Victor
