SYMPHONY

SYMPHONY is a mixed signal simulator combining a fast simulator for digital subcircuits with a traditional nonlinear solver a\*` la SPICE for the analog subcircuits. SYMPHONY uses dynamic circuit partitioning to fully exploit the latency and multirate behavior of the circuit. A new PWL model is used for bipolar devices in digital parts of the design to further speed up the simulation. SYMPHONY can yield 2\(mu-100\(mu speedup over HSPICE depending upon the amount of analog circuitry present in the design.
