Is there some canonical resource/tutorial I should be looking at to use OpenRAM for sky130? I just want a .lef+.gds and nothing more. I'm getting a little lost in the miles of documentation, including the tutorials page that is amusingly blank (<https://github.com/VLSIDA/OpenRAM/blob/stable/docs/source/tutorials.md>).

Sky130 pdk comes with couple of pre compiled and tested macros

Got it, thanks. Would you recommend I stick to those, or should I risk it with using OpenRAM to make new sizes?

Also, apologies, do you happen to know where the SRAM macros are? I'm seeing these ReRAM cells, but in <https://github.com/google/skywater-pdk|google/skywater-pdk> I'm failing to see any SRAM.

<@U023KGDQ6US> If you’ve installed the skywater pdks with open_pdks or volare, the sram macros should be in `$PDK_ROOT/$PDK/libs.ref/sky130_sram_macros`.
