Unlike the IC pseudocomponents, NODESET provides
only an initial guess for some net voltages. It does not
clamp those nodes to the specified voltages. However, by
providing an initial guess, NODESET symbols may be
used to break the tie (in a flip-flop, for instance) and make
it come up in a desired state. To guess at the bias point,
enter the initial guess in the Value text box for the VALUE
property. PSpice attaches a voltage source with a 0.0002
ohm series resistance to each net to which an IC symbol is
connected.
These pseudocomponents are netlisted as PSpice .IC and
.NODESET commands. Refer to these commands in the
online OrCAD PSpice A/D Reference Manual for more
information. Setpoints can be created for inductor
currents and capacitor voltages using the IC property
described in Setting initial conditions
on page A-378.
