Does anybody know how to load the data from OpenLane flow to OpenROAD gui? I want to see the timings, etc

@Matt Venn Same question here…

You can run the flow with -gui to have it load up

It is just empty. What data can I load to make timings available

You would need to reload the liberty, sdc, and spef files

for openlane flow

openroad 
read_lef tmp/merged.nom.lef
read_def results/routing/name.def
gui::show
