SPICE Output Decoder

The next program decodes a SPICE output file and produces four postscript files. The files are:

• signal.ps, the input signal without noise.
• noisy.ps, the input signal with noise.
• out.ps, the output signal.
• line.ps, the output signal with dotted lines representing tripped fuses.

The program comes with a Makefile, so compilation can be performed simply by typing make on the command line. The core program is called spdec. It is invoked by a shell script which extracts the critical features from the single input file into separate files, ready for spdec to process them. Therefore, decoding is done by invoking the shell script:
