Wikipedia / Spectre Circuit Simulator

Spectre is a SPICE-class circuit simulator owned and distributed by the software company Cadence Design Systems. It provides the basic SPICE analyses and component models. It also supports the Verilog-A modeling language. Spectre comes in enhanced versions that also support RF simulation (SpectreRF) and mixed-signal simulation (AMS Designer). A massively parallel version, Spectre X, was also released to provide performance gains while maintaining the same accuracy as previous Spectre versions.
