SIRC

SIRC - Digital Logic and Circuit Simulation Engine

SIRC is a lightweight, fully typed Python library for simulating digital logic at the transistor level. It models Nodes, Devices, and Transistors and computes stable LogicValues through fixed-point iteration and dynamic connectivity.

📦 Installation

Install from PyPI:

pip install sirc

Import the device simulator:

from sirc.simulator.device import DeviceSimulator

🚀 Quick Start

from sirc.simulator.device import DeviceSimulator
from sirc.core.logic import LogicValue
from sirc.core.transistor import NMOS, PMOS
from sirc.core.device import VDD, GND, Input, Probe, Port

sim = DeviceSimulator()

# Create Devices and Transistors
vdd = VDD()
gnd = GND()

inp = Input()
probe = Probe()

inp_port = Port()
out_port = Port()

pmos = PMOS()
nmos = NMOS()

# Register Devices and Transistors
sim.register_devices([vdd, gnd, inp, probe, inp_port, out_port])
sim.register_transistors([pmos, nmos])

# Connect Components
sim.connect(inp.terminal, inp_port.terminal)
sim.connect(inp_port.terminal, pmos.gate)
sim.connect(inp_port.terminal, nmos.gate)
sim.connect(vdd.terminal, pmos.source)
sim.connect(gnd.terminal, nmos.source)
sim.connect(pmos.drain, out_port.terminal)
sim.connect(nmos.drain, out_port.terminal)
sim.connect(out_port.terminal, probe.terminal)

# Simulate and Sample Output
inp.set_value(LogicValue.ONE)
sim.build_topology()
sim.tick()
print(repr(probe.sample()))

# Change Input and Resimulate
inp.set_value(LogicValue.ZERO)
sim.build_topology()
sim.tick()
print(repr(probe.sample()))
