README - a brief documentation on the package (student version) Jan. 2015 by Guoyong SHI: [email protected]

This circuit parser provides an interface to MATLAB so that students can directly use MATLAB for circuit simulation.

This package contains the following files: Makefile parse.lex parse.y parse_func.h[.c] Symbol_Table.h[.c] MNA_Matrix.h[.c] main.c -- the Linux OS driver

You should have installed CYGWIN (or a Linux equivalent) to compile the flex-bison programs and run makefile. You should also have installed a version of MATLAB on Windows or Linux.

The programs "parse.lex" and "parse.y" are compiled in CYGWIN by running "make".

Then in MATLAB, run the mex compiler as follows: mex -DMATLAB mex_parse.c parse_func.c Symbol_Table.c MNA_Matrix.c

To run the parser in Linux, compile as follows:

make parse
make runparse

Depending on your need, the reader is expected to add more C-programs.

The basic funtionalities are

"parse_func.h[.c]" provide the parsing functions that interfacing from the parser "parse.y" and the symbol tables;

"Symbol_Table.h[.c]" manages the symbol tables.

"MNA_Matrix.h[.c]" manages the matrices resulting from parsing a netlist.

This package is incomplete and only provides a code skeleton for continuing development. The details on the necessary components will be introduced in the course.

For more information on this package, please consult TA or instructor.
