Viewing analog results in the
PSpice window
Capture provides a special WATCH1 part that lets you
monitor voltage values for up to three nets in your
schematic as a DC sweep, AC sweep or transient analysis
proceeds. Results are displayed in PSpice.
To display voltage values in the PSpice window
1 Place and connect a WATCH1 part (from the PSpice
library SPECIAL.OLB) on an analog net.
2 Double-click the WATCH1 part instance to display the
Parts spreadsheet.
3 In the ANALYSIS property column, type DC, AC, or
TRAN (transient) for the type of analysis results you
want to see.
4 Enter values in the LO and HI properties columns to
define the lower and upper bounds, respectively, on
the values you expect to see on this net.
5 Repeat steps 1
through 4 for up to two more WATCH1
instances.
6 Start the simulation.
For example, in the schematic fragment shown below,
WATCH1 parts are connected to the Mid and Vcc nets.
After starting the simulation, PSpice displays voltages on
the Mid and Vcc nets.

that you can investigate the behavior.
