............................................................................................................................................................ 1 INTRODUCTION 1-1 C H A P T E R 1 GETTING STARTED 1.1 Introduction TopSpice is a native full-featured mixed-mode, mixed-signal, circuit simulator capable of simulating circuits containing any arbitrary combination of analog devices, digital functions and high-level behavioral blocks. With TopSpice you can verify and optimize your design from the system to the transistor level. By using the built-in logic simulator to simulate the digital sections of your circuit instead of analog equivalents, mixed-mode simulation times can be reduced by orders of magnitude. TopSpice offers a fully integrated environment to capture, simulate, and analyze your circuit designs. Its flexible architecture allows the designer to integrate all the design tools, including third party tools and model libraries, into a complete CAD system. TopSpice is also unique in that it offers you the choice to design from schematic drawings, SPICE netlist (text) files or mix of schematic and netlist, or switch between them. All design and simulation functions are available from either the schematic or netlist editor front-ends. The TopSpice software consists of the following integrated component programs: Schematic Editor, Circuit File Editor, Simulator, Output File uploads/s3/ users-guide 13 .pdf
