Is there anything holding back the Low Power Standard Cell library from being supported in OpenLane?...

Is there anything holding back the Low Power Standard Cell library from being supported in OpenLane? It's still not built and installed even when building the full PDK in v0.23 (unless I've done something wrong)

Until you set the std cell env library by default openlane only builds High Density PDK

Yes, I know that. Per the OpenLane documentation you can run

make full-pdk

to install all SCLs. However, from the Makefile

Copy code

.PHONY: all-skywater-libraries
all-skywater-libraries: skywater-pdk
	cd $(PDK_ROOT)/skywater-pdk && \
		git submodule update --init libraries/sky130_fd_sc_hd/latest && \
		git submodule update --init libraries/sky130_fd_sc_hs/latest && \
		git submodule update --init libraries/sky130_fd_sc_hdll/latest && \
		git submodule update --init libraries/sky130_fd_sc_ms/latest && \
		git submodule update --init libraries/sky130_fd_sc_ls/latest && \
		git submodule update --init libraries/sky130_fd_sc_hvl/latest && \
		git submodule update --init libraries/sky130_fd_io/latest && \
		$(MAKE) -j$(THREADS) timing
