Affirma Spectre Circuit Simulator User Guide 2 Getting Started with Spectre This chapter discusses the following topics: Using the Example and Displaying Results on 2 Sample Schematic on 3 Sample Netlist on 6 Instructions for a Spectre Simulation Run on 11 Viewing Your Output on 14 December 1999 2-1 Affirma Spectre Circuit Simulator User Guide Getting Started with Spectre Using the Example and Displaying Results ® In this chapter, you examine a schematic and its Affirma™ Spectre circuit simulator netlist to get an overview of Spectre syntax. You also follow a sample circuit simulation. The best way to use this chapter depends on your past experience with simulators. Carefully examine the schematic (“Sample Schematic” on 3) and netlist (“Sample Netlist” on 6) and compare Spectre netlist syntax with that of SPICE-like simulators you have used. If you have prepared netlists for SPICE- like simulators before, you can skim “Elements of a Spectre Netlist” on 7. With this method, you can learn a fair amount about the Spectre simulator in a short time. Approach this chapter as an overview. You will probably have unanswered questions about some topics when you finish the chapter. Each topic is covered in greater depth in subsequent chapters. Do not worry about learning all the details now. To give you a complete overview of a Spectre simulation, the example in this chapter includes the display of simulation results with Analog Waveform Display (AWD), a waveform display tool that is included with the Spectre simulator. If you use another display tool, the procedures you follow to display results are different. This user guide does not teach you how
