feature catalog

ngspice‑46 + OpenVAF‑r

Every capability added across 459 enhancements, grouped into feature areas — a feature usually spans several enhancements. Two code bases: the OpenVAF‑r Verilog‑A/OSDI compiler and the ngspice circuit simulator. Each chip links to its write‑up.

Verilog‑A scope targets the LRM Annex‑C analog subset via OSDI (not full AMS). Chips link to enhancements_doc/Enhancement‑N.md on GitHub; a few grouped or early enhancements share a doc. The genuine remaining gaps (fast‑SPICE parallelism, device aging, RC model‑order reduction, mixed‑signal AMS) are tracked in the repo's gap analysis.
