Engine check: ngspice in your browser, compared with ngspice on a PC
This page runs ngspice 47, compiled to WebAssembly, inside a background worker in your browser.
It simulates the fixture circuits from the Solved Circuits channel and compares every number with what
native ngspice 47 and ngspice 42 computed for the same files on a PC (recorded with ngspice -b).
The rule: the numbers must agree to 6 significant figures.
