The SRAM build space is currently empty, only a placeholder is currently provided.

The components of the SRAM build space (compatible with OpenRAM) will be released at a future date.

Before these files are released access to these files is available through SkyWater directly under NDA.

This should have already been released but there have been some delays with the memory compiler.

that's really good, it's hard to user from openRam to build

Since it's been roughly a year, could I have an update on this?

This could be better documented but the build space has been published.

The SRAM build space itself was published at https://github.com/google/skywater-pdk-libs-sky130_fd_bd_sram back in October last year.

The configuration to use this build space with OpenRAM memory compiler is included directly in the OpenRAM repository at https://github.com/VLSIDA/OpenRAM/tree/stable/technology/sky130

Some precompiled SRAM macros are published by efabless at https://github.com/efabless/sky130_sram_macros

Its nice, but OpenRAM is very bad documented.
