Setting up analyses

Output variables
Certain analyses (such as noise, Monte Carlo, sensitivity/
worst-case, DC sensitivity, Fourier, and small-signal DC
transfer function) require you to specify output variables
for voltages and currents at specific points on the
schematic. Depending upon the analysis type, you may
need to specify the following:
• Voltage on a net, a pin, or at a terminal of a
semiconductor device
• Current through a part or into a terminal of a
semiconductor device
• Adevice name
If output variables or other information are required,
select Output File Options in the Monte Carlo/Worst Case
dialog box and enter the required parameters.
Voltage
Specify voltage in the following format:
v[modifiers](<out id>[,<out id>]) (1)
where <out id > is:
<net id> or <pin id>(2)
<net id> is a fully qualified net name (3)
<pin id> is <fully qualified device name>:<pin name>(4)
A fully qualified net name (as referred to in line 3 above)
is formed by prefixing the visible net name (from a label
applied to one of the segments of a wire or bus, or an
offpage port connected to the net) with the full
hierarchical path, separated by periods. At the top level of
hierarchy, this is just the visible name.
A fully qualified device name (from line 4 above) is
distinguished by specifying the full hierarchical path
followed by the device’s part reference, separated by
period characters. For example, a resistor with part
reference R34 inside part Y1 placed on a top-level
