WhatA company that designs, validates, and licenses the 'missing' analog and mixed-signal IP blocks (PLLs, IO pad drivers, USB PHYs, memory interfaces) that open-source SoC projects need to go from simulation to working silicon.
SignalMultiple commenters noted surprise that RISC-V cores are open but the surrounding analog IP is closed — the gap between a working CPU in simulation and a real chip is almost entirely in these proprietary peripheral blocks, and this frustration is a recurring theme in the open hardware community.
Why NowThe RISC-V ecosystem has matured to the point where the CPU core is solved, but analog IP remains the bottleneck; meanwhile, older process nodes are becoming more accessible through programs like Google/Skywater's open PDK initiative.
MarketOpen-source chip projects, RISC-V startups, and university research groups; analog IP licensing is a subset of the ~$6B semiconductor IP market dominated by Synopsys/ARM; the gap is that no one packages analog IP specifically for the open-source silicon community.
MoatSilicon-proven analog IP at specific process nodes is extremely hard to replicate — each block requires expensive test chips and months of characterization, creating high barriers to entry.
