SMASH was born true mixed mode simulator. Unlike its competitors, a single program handles both analog and digital signals! SMASH is the only genuine mixed signal, multi-level simulator on the market today.

A mixed signal solution

SMASH promotes a simulation as natural as mixed signal schematics entry, using as input a circuit description, natively mixed signal. In this way, SMASH makes obsolete the need to divide a mixed signal netlist into one logic and one analog simulator.

SMASH simulates any mixture of analog and digital components, using the best algorithms and providing complete interaction between the logic and analog parts. The result is an immediate simulation start. The only necessary tuning is for optimizing the simulation engine, but, once this is done, results are interactively displayed on the screen.
