feat: expand SPICE component catalog (fases 9 + 10)
Adds 44 SPICE mappers, 58 custom metadata entries, and 12 visual
Web Components covering logic gates, transistors, op-amps, regulators,
sources, electromechanical parts and integrated-circuit packaging.
Fase 9 — component catalog expansion
------------------------------------
- 7 logic gates (AND/OR/NAND/NOR/XOR/XNOR + NOT) as SPICE B-sources
- 8 multi-input gates (AND/OR/NAND/NOR with 3 and 4 inputs)
- 9 transistors: 5 BJTs (incl. PNP 2N3906/BC557) + 4 MOSFETs (incl.
P-channel IRF9540/FQP27P06). NMOS refactored from Level=3 W=0.1
(hangs ngspice) to Level=1 with sane W/L
- 5 op-amps: LM358, LM741, TL072, LM324 with per-chip saturation
rails + opamp-ideal
- 4 linear regulators (7805, 7812, 7905, LM317) with dropout
- 3 batteries (9V, AA, coin-cell) with realistic ESR
- Signal generator (sine / square / DC)
- 2 Schottky diodes (1N5817, 1N5819) + photodiode (lux-driven
current source)
Fase 10 — electromechanical + ICs
---------------------------------
- Relay (SPDT): coil + L + S-switch with native hysteresis +
flyback diode, inverted-control trick for the NC contact
- Optocouplers 4N25 and PC817 (LED + CCCS with CTR=0.5 / 1.0)
- 7 74HC ICs as DIP-14 packages emitting 4 or 6 B-sources per
component (first mapper pattern emitting multiple device cards)
- 3 flip-flops (D, T, JK) — digital-sim only (edge detection is
not representable in ngspice .op)
- L293D dual H-bridge motor driver
Infrastructure
--------------
- scripts/component-overrides.json gains a _customComponents[] array
that lets new Velxio-only parts survive metadata regeneration
(previously applyOverrides() could only patch wokwi-elements
components that had already been scanned)
- scripts/generate-component-metadata.ts injects custom entries
before the patch loop
- New ComponentCategory values: 'logic', 'analog', 'electromech'
- frontend/src/components/DynamicComponent.tsx PASSIVE tracing
extended from just ['resistor','resistor-us'] to 9 two-terminal
passives with per-part pin name maps
- New CI workflow test-circuit.yml runs the sandbox on push/PR
- frontend-tests.yml regenerates metadata and fails if committed
JSON is stale
- Documented 2 new ngspice gotchas in circuit-emulation-gotchas.md:
unicode in netlist titles silently hangs the parser, and
MOSFET Level=3 + W=0.1m causes .op to hang
- 164/164 sandbox tests passing in ~9 s (was 88 pre-fase-9)

"$comment" : "Custom property overrides applied AFTER auto-generation from wokwi-elements. Add entries here to customize controls, add new properties, or change defaults. These survive metadata regeneration. Use `_customComponents` to inject Velxio-only parts not defined in wokwi-elements." ,
