File Types
DR. SPICE Input Files
DR. SPICE accepts the following input file formats:
- .cir - The .cir file is the circuit file. It contains the circuit to be simulated and the simulation parameters. This file can be typed manually with a
text editor or created automatically by a schematic capture program
- ..lib - The .lib file is an external file that contains one or more device models. This file is referenced by a library statement in the circuit file.
- .include - The .include file is a file whose path name is specified in the circuit file in a .INCLUDE Include statement, and the contents readin
when the circuit file is processed by DR. SPICE. For example, this file may have the form device.lib, containing model parameters for a class
of circuits, and it is read in as a model library. (Note that .include is not part of the file name.).
- .loadbias - The .loadbias file contains the bias point node voltages produced by a circuit simulation and saved as a .savebias Loadbias output
file. This file provides input for successive simulations.
DR. SPICE Output Files
DR. SPICE can produce the following output file formats:
- .out - This is the SPICE file format for event reporting. Unlike a CSDF file, which contains actual simulation data, this file contains interpolated
results.
- .savebias - This file contains bias point node voltages produced during circuit simulation, which become input (see .loadbias) for successive
simulations.
- .txt (CSDF) - An ASCII file containing the actual simulation results from a DR. SPICE simulation. Common Simulator Data Format (CSDF)
is the industry standard file format for storing analog simulation results.
- .bxt - A binary version of the .txt (CSDF) file.
- .raw - Yet another format for simulation results based on the Berkeley standard SPICE binary file format.
- .dat- Our proprietary waveform database format.This is the default that DR. SPICE uses to internally save waveforms during a simulation
session. It's primary advantage is high speed access.
