@Tholin: The GF SRAM was used in the Caravel management SoC, although we only used one of the GF macros (GF180_RAM_512x32). This macro is working on the GF MPW silicon. The repository of the Caravel management SoC is https://github.com/efabless/caravel_mgmt_soc_gf180mcu (specifically, see

verilog/rtl/sram.v

). Are you able able to get any other signs of life from your user project?
