Dolphin Smash is a mixed-signal, multi-language simulator for IC or PCB designs. It uses SPICE syntax for analog descriptions, Verilog-HDL and VHDL for digital, Verilog-A/AMS, VHDL-AMS and ABCD (a combination of SPICE and C) for analog behavioral, and C for DSP algorithms. License: Free To Use But Restricted Changes: Numerous enhancements including hierarchical analog power computing, computing and tracing of analog net resistive and capacitive impedance, and PSP (Penn State and Philips) and EKV3 MOSFET models.
