Electrical Circuits

Draw IEEE-style schematics and export SPICE netlists for simulation. Runiq supports common components, net naming, and multiple analysis types.

Components

• Passive: R, L, C
• Sources: V (voltage), I (current)
• Diodes and Transistors: D, Q (BJT), M (MOSFET)
• Op-amp: OPAMP (symbolic)

Example:

schematic "RC Lowpass Filter" {
	net IN, OUT, GND
	part V1 type:V source:"SIN(0 1 1k)" pins:(IN,GND)
	part R1 type:R value:"10k" pins:(IN,OUT)
	part C1 type:C value:"1n" pins:(OUT,GND)
	analysis tran "0 5m"
}

Net naming

• Always define a reference node, e.g., GND
• Use descriptive names: VCC, VIN, VOUT

Analysis types

• op: DC operating point
• tran: Transient (time-domain)
• ac: Frequency response (Bode)
• dc: Parameter sweeps

analysis op
analysis tran "0 10m"
analysis ac "dec 50 100 10k"
analysis dc "VIN 0 10 0.1"

Value suffixes

Standard SPICE suffixes: f, p, n, u, m, k, Meg, G

Export

• CLI (planned): runiq circuit.runiq --export spice -o circuit.cir
• API: io-json and renderer hooks for SPICE

Examples

• RC Lowpass, Voltage Divider, Op-amp Amplifier, RLC Resonant
