Abstract

The software described in this article is used to convert DAISY DLS (Dynamic Logic Simulator) tabular output files into ASCII character timing charts which are much easier to employ when interpreting simulation runs and determining the functionality of gate array and ASIC (Application Specific Integrated Circuit) designs. This program, which allows detailed timing analysis of chip designs, represents a significant move toward obtaining both a reduced design cycle and higher quality components.

Timing Chart Pulse Width And Edge Analyzer

      The software described in this article is used to convert DAISY
DLS (Dynamic Logic Simulator) tabular output files into ASCII
character timing charts which are much easier to employ when
interpreting simulation runs and determining the functionality of
gate array and ASIC (Application Specific Integrated Circuit)
designs.  This program, which allows detailed timing analysis of chip
designs, represents a significant move toward obtaining both a
reduced design cycle and higher quality components.

      The DAISY work station provides tabular output files which are
employed to interpret simulation runs and to determine the
functionality of a design.  This requires the manual calculation of
timing or edge deltas or pulse widths. Automatic calculation
accompanies the use of the described software program which provides
for conversion of the tabular output files into a more useable timing
chart/signal analysis format, and may be employed either as signal
edge analyzer or timing chart generator.  In the first case, the
program translates the tabular output file into a ASCII character
timing chart, including timing information for all edges.  The timing
information consists of the pulse width for every change in signal
value.  In the second application, the tabular file is converted into
an ASCII character timing chart, with all edges indicated as a row of
'>>>>>> or <<<<<<' depending on whether the edge is a rising or
