In an SDR's FPGA design, two always blocks each drove the same registers. Icarus resolved it by statement order, so every simulation passed, 21 of 21. Synthesis sees two drivers per register. Verilator flagged it, but the repo's lint gate did not classify that code, so lint just failed 4 of 5 with no clear reason. The same PR imports a new board revision and notes the firmware check was skipped on that host because arduino-cli was not installed.

From the Grok pain-radar digests, Nov 11-12 2026 (Nov 11 8:41 AM ET through Nov 12 5:41 AM ET digests plus the Haitch editions). Verified live 2026-11-12: issue/PR read; title and state confirmed.
What it costs a team
Modeled annual cost
$30,000
For a team of 5
Prototype delay
3 days
Modeled schedule slip per occurrence
Time lost

Evidence
More recurring errors in Code-SDR (iamdarshg)
- A fabrication candidate SDR board fails a fresh kicad-cli DRC with 391 violations: 199 footprint-library mismatches, 116 dangling vias and 76 dangling tracks. The same run reports zero unconnected items, which the author says proves nothing about routing. The ask is to gate fab export on a passing DRC receipt for the exact board hash and stop errors being masked by continue-on-error or || true.ECAD · impact 74
- A second orchestration swarm (DeepSeek-based) announced it is working the same six hardware repos in parallel with a Claude Code orchestrator, with written rules about who is authoritative, branch names and commit trailers so the two can read each other's intent. It reproduced the handoff's KiCad DRC baseline of 222 violations (199 footprint-vs-library mismatches). The handoff also records that a curated silk restore brought 222 down to 71 but introduced 47 new mismatch identities, which a count-based gate cannot see, so its proposal is to gate on the set of violation identities (UUID per item), not the counts.ECAD · impact 74
- On the same board, five RF50 nets lack complete pad-to-track connectivity, protected RF segments are 0.10 to 0.15 mm against a nominal 0.23 mm, and signals are routed on In1/In2, which the documented stackup reserves for ground and power planes. KiCad still says zero unconnected. The stackup lives in a document, and nothing in the layout tool knew about it.ECAD · impact 74
