KING FAHD UNIVERSITY OF PETROLEUM AND MINERALS DEPARTMENT OF ELECTRICAL ENGINEERING Electronic Circuits II – EE303 Tutorial # 1 Net Listing and Simulation Analysis Using SPICE OBJECTIVES 1. Describe net listing and simulation analysis using SPICE. 2. Introduce diodes and transistors’ models used in SPICE. 3. Explain additional SPICE commands and test new circuits. 4. Test new circuits using default and commercial parameters. INTRODUCTION Currently, one of the more widely used general purpose circuit simulation program for industrial and academic computer systems is SPICE. As you know SPICE can be used to simulate circuits containing resistors, capacitors, inductors, mutual inductors, independent and dependent voltage and current sources, and basic semiconductor devices. In EE 203 students were using Schematic Editor of SPICE to draw circuits and then run simulation analysis. In fact, drawing circuits and ensuring correct interconnections may be time consuming. Alternatively, circuits can be described in SPICE by specifying their various components and their terminal connections (net listing). A typical SPICE input file format is as follows: Notes: TITLE STATEMENT CIRCUIT ELEMENTS: Power Supplies / Signal Sources Circuit description/Element Descriptions Model Statement * Comments CONTROL COMMANDS: Analysis Requests Output Requests * Comments .END 1. The first line must be a title line which is usually reflects the file contents. It cannot be omitted. 2. The last line must be the .END statement. 3. You can insert comment lines starting with "*". 2
4. You can use upper or lower case letters. 5. The following subsections explain how to describe elements and use the control commands. CIRCUITS ELEMENTS 1. The general format for describing independent voltage source is Vname N+ N- [DC value] [AC Magn phase] or [SIN V 0 V a freq td df phase] Where The voltage source must start with letter V. N+ and N- are the positive and negative nodes of the source, respectively. Sources can be assigned values for dc analysis [DC value], ac analysis [AC magnitude phase], or transient analysis [SIN]. The ac phase angle is in degrees. The parameters of the sin are given in this order: dc offset, amplitude, frequency, delay, damping factor, phase, respectively. In most cases there is no need to specify td, df, and phase but rather leave SPICE use their default values of zeroes. Other the transient signal generators such as PULSE and PWL are introduced in Experiment 3. 2. An independent current source can be described similarly but using Iname to replace Vname. But note that current flows from a positive node to the negative node. 3. Various dependent sources are defined when needed in Experiments 3 and 4. 4. Passive elements are described by element statements that specify the type-name and terminal connections as follows: Rname N1 N2 value Cname N1 N2 value Lname N1 N2 value 5. Semiconductor devices such as diodes, MOSFETs and BJTs are described by two statements. In addition to an element statement, a model statement is required. SPICE allows varying degrees of circuit element model complexity. In this tutorial we intend to provide basic default model descriptions and more complex model descriptions. Examples will be used to illustrate the differences between the results obtained using hand calculations, default device models and complex device models. By the end of this tutorial we expect that the student will get an appreciation of the advantages of using SPICE complex models. The following subsections briefly described element and model statements for basic semiconductor devices. 3
