Notes LibreBMC Charter Status: Call for participation went out May 10 14 day window closes May 26 Expect first official meeting to be May 27, need to send that out to membership Workgroup organization
A2P, Bill Flynn A2P started from VexRISC-V and converted it to POWER ISA 32b core See presentation in Google Drive A2P folder for details A2P is currently ~5400 LUTs, VexRISCV is around 2000 LUTs Possible differences 1000 LUTS for GPR implementation in FF vs BRAM Hazard logic is more complex in POWER May have more hardcoded instructions vs microcoded in VexRISCV
Open Items
Git repository items
Core selection
FPGA Components / Status
Action Items
Start document of links to tools and hardware for others to replicate work.
Diagram of all open tools, how they fit together, what is missing, what needs significant improvement - FuseSoc, OpenLane, Symbiflow, Yosys, openroads, etc https://github.com/hdl
EDA Tooling - Containers - https://github.com/hdl/containers
Make sure these support Power. I believe that Rob Taylor added Power support.
EDA Tooling - Conda - https://hdl.github.io/containers/
EDA Tooling - if you are a Bazel fan; https://github.com/hdl/bazel_rules_hdl Used by Google’s XLS team -> http://github.com/google/xls
Add current projects that you are working on that relate to LibreBMC or opentools. Plan would be to schedule presentations on them to stir conversation and collahttps://notes.openpower.foundation/T0w6qPMJQkaj_u-UTvkUAQ?both#boration. This will highlight areas where technical issues can be worked across projects. Next Meeting Agenda Items
Future topics
