Follow these steps to generate and analyze congestion reports using Report Design Analysis:
- In the same Vivado session where the
placer and router ran, generate the congestion tables by
running:
report_design_analysis -congestion - Review the generated congestion tables, which show congested areas as seen by the
placer and router.
- The Module Names in the report correspond to the hierarchical cells present in each reported tile.
- Retrieve the complete name of a module by
running:
get_cells -hier <moduleName> - After identifying the hierarchical cells present in the congested area, apply congestion-alleviating techniques to try reducing overall design congestion.
