The Arizona State University's 7nm Predictive PDK (ASAP7) was developed at ASU in collaboration with ARM Research, and is available under the BSD 3-Clause license.
As the ASAP7 enablement does not have memory generators, we use the FakeRAM2.0 memory generator available in the FakeRAM2.0 (commit tag: MacroPlacement.ISPD23) 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.
The ./lef directory contains the technology, standard cell and macro lef files, the ./lib directory contains the standard cell and macro liberty files and the ./qrc directory contains the qrc technology file.
