Hello, I was generating the global route congestion file as per OR-flow-scripts, but the file does not actually save into reports directory. Meanwhile the global routing congestion is viewable (or generated) in GUI by clicking. But i figure these two might be separate. Does anyone have any idea what's going on?

global_route -guide_file $env(RESULTS_DIR)/route.guide \

-congestion_iterations 100 \

-congestion_report_file $env(REPORTS_DIR)/congestion.rpt \

-verbose

do

echo $env(REPORTS_DIR)

and see where it points

Using the default design_config (gcd/nangate45) i get

./reports/nangate45/gcd/base/congestion.rpt

Yes. If there is no congestion, the report file will be empty or not get generated by default

Understood, thanks!
