Circuit Simulation

DEX uses the SPICE 3f5 circuit simulator.

SPICE is an analog-circuit simulator that is used to calculate and display the circuit behavior. It was originally developed at the Electronics Research Laboratory of the University of California, Berkeley (1975). The source code was made freely available and has been used as the basis of many commercial simulators, and academic projects.

SPICE is a useful tool, not a magic wand, and its results should always be examined critically; in some cases it may not give results at all, for others the results may be misleading.
