Command Line Interface

tsci simulate

tsci simulate runs circuit simulations on your tscircuit designs. Currently it supports analog SPICE simulations.

Usage​

tsci simulate <file> [options]

Arguments​

  • file (required) – path to a tscircuit .tsx or .circuit.json file

Options​

  • --disable-parts-engine – disable the parts engine during circuit evaluation
  • --output <directory> – fresh report directory (spiceEngine="pcb_spice" only)
  • --solver-timeout-ms <milliseconds> – per-process solver timeout, default 900000 (spiceEngine="pcb_spice" only)

The engine comes from the spiceEngine of the experiments in the file:

  • "ngspice" – generates a SPICE netlist from the schematic, runs ngspice and prints the results as a table.
  • "pcb_spice" – extracts the routed copper with FastHenry and FasterCap, runs ngspice with IBIS buffer models and writes results.html to .tscircuit/simulation-<file>-<timestamp>/. Requires fasthenry, FasterCap and ngspice on PATH.

One file can't mix pcb_spice with other engines. See Simulating PCB Traces with tsci simulate.

tsci simulate return-current​

Run a PCB return-current EM simulation with Palace. See <simulation.pcbreturncurrentsimulation />.

Example​

$ tsci simulate my-circuit.circuit.tsx
ngspice 1 -> ngspice 1 -> 
Note: No compatibility mode selected!


Circuit: * circuit json to spice netlist

ngspice 2 -> Doing analysis at TEMP = 27.000000 and TNOM = 27.000000

Using SPARSE 1.3 as Direct Linear Solver
Operating point simulation skipped by 'uic',
  now using transient initial conditions.
