-As the FreePDK45/NanGate45 enablement does not have memory generators, we use the bsg_fakeram memory generator that is available on the [bsg_fakeram](https://github.com/jjcherry56/bsg_fakeram) GitHub repo.

 With this combined enablement, testcases with SRAMs can be synthesized, placed and routed using both proprietary (commercial) tools such as Cadence Genus/Innovus, and open-source tools such as OpenROAD.
