Assignment 1a

• Due: Monday September 16, in class
• Write a Java program to
  1. read a Spice file circuit definition (ignoring all non-component definition elements) from a local file. The name of the file should be a parameter to the program.
  2. output component-by-component English description of circuit to standard output. In other words use the object created by
     new FileOutputStream( (new FileDescriptor).out )
     (assuming you've done an import java.io.*; first)
     or System.out.println().
     One line per (recognized) component is expected.
  3. Read and Output only the following components (for now):
     1. resistors (3.1.1)
     2. capacitors (3.1.4)
     3. inductors (3.1.7)
     4. voltage sources (with no distortion) (3.2.1)
     5. current sources (with no distortion) (3.2.1)
     The number in [brackets] refers to the section of the Spice 3 Manual where this element is formally defined.
• Deliverables:
  1. clear text file with exact requirements.
  2. java program file(s)
     - must compile !
     - must run cleanly through javadoc
  3. java test program file(s) (including test data files )
     It is expected that you test your program with approximately 10 test data files, at least 2 of which should be your own.
  4. text file or paper copy of log
• To be delivered on 1 floppy in class with paper log (if applicable)

• small circuit
• Resistive network with dependent sources
• 741 Op-Amp
• Wheatstone Bridge
• Large subcircuit library

• The Spice Club site, in particular in the ready to Simulate subsection of the Tools as well as in the Model library .
• The PSpice site.
