nx_schematic_gate.nx

nx_schematic_gate.nx -- GATE for schematic->netlist (front of the EDA flow). Builds a REAL circuit (a voltage divider: J1 connector + R1 + R2), emits its netlist, and proves it like a real tool: T1 NETLIST -- VIN net has 2 pins, MID has 3, GND has 2 (exact connectivity). T2 ERC CLEAN -- the good circuit has 0 electrical-rule violations. T3 ERC LIAR -- floating a pin raises an ERC violation (real rule bites). T4 NEVER-BRICK-- deterministic ERC re-run. T5 ROUTABLE -- 3 nets are routable (>=2 pins) = 3 routing jobs for place-and-route. T6 HANDOFF -- route one netlist net on the shared router -> routed (schematic -> netlist -> ROUTE, end to end). GREEN iff all pass. Sovereign nx_cc->nxasm, no 3rd-party. expect_exit: 0 license_tier: ORIGINAL
