Hello together :) When instantiating my self-compiled OpenRam macros in openlane2, I noticed a discrepancy in units. The openram generated macros are [hardcoded](https://github.com/VLSIDA/OpenRAM/blob/b6a6f12642df6b84facc24a77f9a6f67a0d62dab/compiler/base/lef.py#L25) as 2000 microns, but openlane2 expects 1000 microns. Did someone face this issue before? Is there an easy way to convert the database units of LEF files? e.g. an open source conversion script? Klayout can convert units, but cannot export LEF format again (instead offers GDS and others). There should be a commercial tool (from Synopsys?), that can do this, but I don't remember its name.

UNITS
  DATABASE MICRONS 2000 ; // 1000 expected
END UNITS

Hello. What happens when you try to integrate the OpenRAM macros using this LEF? It could be the case that OpenROAD can handle different UNITS statements across different LEF files.
