spectre-netlist-gotchas

spectre-netlist-gotchas is a Physics, mathematics & simulation skill for AI agents, published by deanyou in the virtuoso-cli repository on GitHub. Skillspace rates spectre-netlist-gotchas D (59/100) and it passed the safety scan; the rating is based on static analysis only.

Critical Spectre netlist-mode gotchas for standalone simulation (no Virtuoso ADE). Use when: (1) writing Spectre testbench .scs files with `simulator lang=spectre`, (2) noise analysis shows absurd values (megavolts of noise) — oprobe topology is wrong, (3) SFE-30 error on `ac=1` in vsource — use `mag=1` in native Spectre lang, (4) SFE-1997 error on `oprobe=<node_name>` — must be a circuit element not a node, (5) parsing PSF ASCII output from Spectre (dc_op.dc, ac_gain.ac, noise_an.noise), (6) phase margin calculation for inverting amplifier topologies, (7) slew rate measurement gives wrong result with small-signal step — need large signal, (8) ICMR from DC sweep — use transistor region fields, not CM gain (which is ≈ 0), (9) SFE-868 from ADE-generated netlist — oa/lib/../ model path only works in ADE interactive mode.
