DR. SPICE is a circuit simulator that simulates and analyzes analog circuits. DR. SPICE allows you to analyze and modify your circuit design for optimal performance. This tool can be used standalone or in conjunction with a schematic capture system.

We offer popular platform support for Windows (3.1, 95, NT 3.5.1) and UNIX workstations. DR. SPICE also supports common SPICE netlists and models, including those based on Berkeley SPICE 2G6 and PSPICE. 64 bit floating point arithmetic and a state-of-the-art sparse matrix solver provide fast simulation, robust convergence and high accuracy.
Used in conjunction with a schematic
capture system, you achieve a solution for the entire analog
design. DR. SPICE can be driven directly from schematic capture
programs by ViewLogic, OrCAD, and Protel.
Our simulation library contains
approximately 9000 models, including our analog library and
libraries developed by leading semiconductor manufacturers.
Advanced built-in models include BSIM and MESFET's. With no
built-in circuit size limits, DR. SPICE breaks the 640k limit,
thus allowing you to take advantage of all the memory in your
machine! DR. SPICE runs 32-bit addessing on 486 machines and runs
on any 486DX, Pentium, or compatible processor with 16MB of
RAM. A comprehensive analysis toolset provides a plethora of
design aids right at your fingertips!

DR. SPICE has built-in behavioral models that allow you to
characterize complex circuits as one of the following:
