@Burak Aykenar siliconcompiler orchestrates open/proprietary tools/pdks, mainly in Python (and some Tcl) - think of it as a kind of "OpenROAD/OpenRoadFlowScripts/OpenLane + some open source frontend HDL tools like chisel, bambu, surelog (for system Verilog), + open pdks + (optional) proprietary tools/pdks". Silioncompiler is a "moving target" - currently its v0.96. I'm not involved, ask anderas olofsson for details: https://github.com/siliconcompiler/siliconcompiler/blob/main/docs/papers/sc_dac2022.pdf
