This design will run under any MicroSim Schematics program. It can be simulated under any MicroSim simulator except for MicroSim PLogic. The design can be packaged for export to layout. Required Symbol libraries: analog.slb source.slb port.slb bipolar.slb eval.slb (if using the evaluation version) Required model libraries: bipolar.lib eval.lib (if using the evaluation version) Required package libraries: bipolar.plb eval.plb (if using the evaluation version) This circuit and tutorials associated with it can be found in the Circuit Analysis Users Guide. They are an excellent way to learn the basics and many of the more advanced features of any of the MicroSim packages.
