I noticed that the supply rails are named without exclamation points, so does that mean I have to either explicitly connect all the VPWR together and all the VGND together or power each connected component separately? I guess I can relabel the power rails as well.

@Vitit Kantabutra Using trailing

on signal names to indicate a virtual connection is a Calibre convention, I believe. magic does not have the same convention. With openlane, the standard cells should be automatically connected to the appropriate power rails. If you are using hardened macros, be sure to include the
FP_PDN_MACRO_HOOKS
directive.

Thanks. I thought Magic had that convention.
