Abstract

A simulation description generator (SDG) program is described that can be used in very large-scale integration (VLSI) circuit computers to automatically create a summary of VLSI device states which are entered during the course of simulation. The program provides a test case trace which can produce information on actions performed, device states exercised and input data for other software to produce device test programs.

Simulation Description Generator Program

       A simulation description generator (SDG) program is
described that can be used in very large-scale integration (VLSI)
circuit computers to automatically create a summary of VLSI device
states which are entered during the course of simulation.  The
program provides a test case trace which can produce information on
actions performed, device states exercised and input data for other
software to produce device test programs.

      Using source code of a design simulation program, SDG compiles
the source code into a brief description of states that the VLSI
device has entered during the course of simulation.  A state and its
SDG output message is specified by defining what is known as a
"terminal file" for the design simulation procedure which defines the
device state. As the SDG compiles the program, any call to a
simulation procedure is checked against the available terminal files.
If a terminal file for that procedure exists, the contents of the
terminal file are sent to the output of the SDG program.  If no
terminal file exists, SDG attempts to compile the source code
contained in the procedure. Comments in the source code can be sent
to the SDG output file to further enhance the readability of the
output file.

      In addition, the SDG program has the ability to generate
simulation descriptions of source code simulation programs.  These
descriptions can be used to: a) give a brief summary of a long source
