@Mitch Bailey,Is there any way to open gds file in Openroad. Else, how can we convert .gds file to .odb file? I have a gds file that comes out of openlane flow, I need to check the heatmap in openroad. Does openlane generates .odb file?

OpenROAD can support to view

.def

with

.lib,.lef

file or

.odb

file format.

.gds

viewed through klayout/magic

Okay ,thanks @Vijayan Krishnan
