From 1,464 Unrouted Nets to Zero — But I'm Still Not Calling This Board Manufacturable
TL;DR Part 2 of letting an AI agent (Codex, driving KiCad through its CLI) design my Raspberry Pi CM4 Mini-ITX IO board. The board is now fully routed and adopted as the official design : ERC 0, DRC 0, unrouted nets 0, schematic↔PCB mismatches 0. Vendor-model power simulations that timed out last time now complete all 12 cases. And yet the strict all-checks pass flag is still false , and I am not…
On October 25, a Raspberry Pi CM4 Mini-ITX IO board was formally verified as routeable and free of errors, with no unrouted nets or mismatches between the schematic and PCB. However, the board remains unreleased and un-manufacturable due to a fault simulation leaving -1.35 V on a power controller pin, which has not yet been explained.
Despite 384 passive SPICE conditions and 12 vendor-model startup simulations passing, the strict all-checks pass flag remains false. The board's silkscreen still labels it as an engineering prototype not to be fabricated.
