ProTip: Doesn't matter how your OpenHW is, unless you're
printing it in an #OpenFab operating under an #OpenAudit
environment whatever comes off the line is still untrustable.
"We're building a chip. A fast chip. A safe chip. A trusted chip,"
explains the web page at Libre-SOC.org. "A chip with lots of
peripherals. And it's VPU. And it's a 3D GPU... Oh and here, have the
Libre-SOC's entirely Libre 180nm ASIC, which can be replicated down to
symbolic level GDS-II with no NDAs of any kind, has been submitted to
IMEC for fabrication.
It is the first wholly-independent Power ISA ASIC outside of IBM to go
Silicon in 12 years. Microwatt went to Skywater 130nm in March;
however, it is also developed by IBM, as an exceptionally well-made
Reference Design, which Libre-SOC used for verification.
Whilst it would seem that Libre-SOC is jumping on the chip-shortage
era's innovation bandwagon, Libre-SOC has actually been in development
for over three and a half years so far. It even pre-dates the OpenLane
initiative, and has the same objectives: fully automated HDL to
GDS-II, full transparency and auditability with Libre VLSI tools
Coriolis2 and Libre Cell Libraries from Chips4Makers.
With €400,000 in funding from the NLNet Foundation [a long-standing
non-profit supporting privacy, security, and the "open internet"],
plus an application to NGI Pointer under consideration, the next steps
are to continue development of Draft Cray-style Vectors (SVP64) to the
already supercomputer-level Power ISA, under the watchful eye of the
upcoming OpenPOWER ISA Workgroup.
