Tutorial
In this tutorial, you will use PSpice A/D to simulate a simple,
mixed analog/digital circuit. You will then use Probe to analyze
the output by:
• simultaneously displaying analog and digital traces along a
common time axis, and
• displaying digital data values and features unique to mixed
analog/digital circuit analysis, such as identification of
digital nets inserted by PSpice A/D.
