Flexible circuit simulation (W.M. Zuberek)
Computer-aided circuit analysis or circuit simulation has become an
established and accepted tool in the area of circuit design. Using this
method circuit designers can easily verify and improve their designs
before the time-consuming and expensive fabrication takes place.
However, existing circuit simulators are usually quite inconvenient
and rather inefficient in applications which require numerous analyses
of circuits with the same topology, but with different sets of parameters.
Interactive circuit analysis, circuit optimization or parameters extraction
are simple examples of such applications. Flexibility needed in such
cases can be provided by an "open" structure of a set (or a package)
of simulation "primitives" rather than a functionally closed program.
SPICE-PAC is a such a circuit simulation
package derived from the popular SPICE simulation program. SPICE-PAC
supports numerous extensions that are not available in the SPICE-like
simulators; many further modifications are being considered, for example
mixed-level, mixed-mode and mixed-domain simulation.
