@antonblanchard just released the vlsiffra project. See the tweet @ https://twitter.com/antonblanchard/status/1580154261962657792

Introducing https://github.com/antonblanchard/vlsiffra/ - a generator of fast and efficient standard cell adders, multipliers and multiply-adders. Written in Amaranth HDL, formally verified with #Yosys. #Verilator verification too With @OpenROAD_EDA + ASAP7 7nm a 32bit 3 cycle multiplier hits 2.7GHz

Some interesting aspects;

vlsiffra is written in the Amaranth HDL language which allows it to be very configurable, including
vlsiffra currently supports the SkyWater sky130hd, GlobalFoundries GF180MCU and ASAP7 PDKs and standard cell libraries.
vlsiffra only requires a few standard cells (full and half adders, 2 input xor, 2 input and, inverter as well as a couple of more complicated cells (ao21, ao22, ao33)

It seems like some of the output of this tool would make excellent OpenROAD regression tests / benchmarks.
