TopSpice is an affordable integrated computer-aided circuit design software package offering advanced native mixed-mode mixed-signal analog/digital/behavioral simulation based on the industry standard SPICE simulator program.

TopSpice is a true analog/digital/behavioral mixed-mode circuit simulator for the PC. It offers the most advanced SPICE simulator in its price range, compatibility, and an easy to use integrated design environment from schematic capture to graphical waveform analysis.

With TopSpice you have the choice to design from schematic drawings, text netlist (SPICE) files or both. All design and simulation functions are available from either the schematic or netlist editor front-ends.

TopSpice includes a native full-featured mixed-mode mixed-signal circuit simulator capable of simulating circuits containing any arbitrary combination of analog devices, digital functions and high-level behavioral blocks. With TopSpice you can verify and optimize your design from the system to the transistor level. By using the built-in logic simulator to simulate the digital sections of your circuit instead of analog equivalents, mixed-mode simulation times can be reduced by orders of magnitude.

TopSpice offers industry standard PSpice and HSPICE compatible* simulation. TopSpice works with most PSpice netlists, manufacturer SPICE model libraries and IC foundry HSPICE libraries.
