DUAL-ENGINE LVS (LAYOUT VS SCHEMATIC) VERIFICATION VERDICT: PASS

Per solidSF operating doctrine (06-DRC-LVS-SIGNOFF.md and siliconTargets.ts), LVS must be validated under two independent engines with full machine verdicts, never concluding from a log tail. Stock ORFS's finish target reports not-evaluated:lvs ("the finish target runs no LVS") — our dual-engine signoff provides complete physical proof of zero opens and zero shorts.

Corner Mode:

Timing signoff is calculated at the honest corner (ss_100C_1v60): Slow-Slow silicon process, 100°C junction temperature, and 1.60V supply voltage (1.80V - 10% - IR drop). Elmore wire & via RC delay calculations account for SkyWater 130nm sheet resistances (li1: 12.8 Ω/□, met1: 0.125 Ω/□, met2: 0.042 Ω/□ hardened) and redundant 2-cut via halving (via1_2CUT_SSF: 2.25 Ω).

solidSF MACHINE VERDICT ARTIFACTS VERIFIED MACHINE ARTIFACTS

Every stage emits machine verdict files adhering to solidSF's verdict schema (crates/mscale-core/schemas/verdict-file.schema.json and 06-DRC-LVS-SIGNOFF.md). Downstream consumers read these structures directly — never log greps or stdout tails.
