This section describes how to run DR. SPICE under Microsoft Windows and includes the following topics:
SPICE users have consistently declared that ease of use is one of their most important criteria in using a simulator. Deutsch Research listened, and paid particular attention to making DR. SPICE as easy to use as possible. A program that is easy to use enables the user to accomplish design goals faster, therefore getting products to market faster.
At Deutsch Research, our design philosophy is to make frequently used functions as close to “one button access” as possible, and to create a superb on-line help system that will enable the user to understand program functionality quickly, whenever needed.
This section demonstrates frequently used functionality, including creating an operating point analysis, a transient analysis, and a sweep analysis. Throughout these examples, the on-line help system is available to help the user get the most out of DR. SPICE.
Performing an Operating Point Analysis
Operating Point Analysis allows you to determine bias conditions and static power consumption.
Performing a DC Sweep and Transient Anaylsis
A DC Analysis is used to determine the DC transfer characteristics of your circuit. A Nonlinear Time Domain Transient Analysis is used to determine the large scale response of your circuit to large scale changes in its inputs as a function of time.
A Sweep Analysis allows the user to sweep a parameter specified in the circuit file. For each value of the swept parameter an analysis, as specified in the circuit file, is performed. The result is a group of plots where each plot in the group corresponds to a unique value of the swept parameter.
In this tutorial, it is assumed that you have an understanding of how to run OrCAD’s Capture program. You will:
Learn how to create a netlist and run that netlist from within DR. SPICE™.
| Selecting a set of simulation results | Multiple Axes | Zooming and windowing |
| Axes types and range | Expressions | Cursor Functions |
DR. SPICE can be invoked with one of the following command line arguments:
Along with the command line argument you need to specify the name of a circuit file.
Model Maker is an integrated part of DR. SPICE, and allows you to quickly create models from databook specifications for the following devices:

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.
DR. SPICE takes a netlist description of a circuit and a set of analysis instructions and simulates circuit operation under the specified conditions. The simulation results are examined as an ASCII text file or displayed as waveforms using it’s state of the art waveform analyzer. You can use the simulation results to optimize the circuit and create a modified netlist. DR. SPICE takes the modified netlist and simulates it; the whole process repeats until the design goal is achieved.
DR. SPICE is an advanced general purpose circuit simulation program. It can perform:
