The PSpice Optimizer Window 3

Error Gau
g
e Area
The error gauge area has an error indicator and shows
information reflecting the overall condition of the optimization.
The error gauge shows how far the goals are from their target
values. Initially, the indicator displays 100%. As the
optimization proceeds, the error falls as the goals approach their
target values. The PSpice Optimizer displays the RMS of the
normalized value of the goals in the RMS Error field.
If all of the specifications meet the target values exactly, the
error is zero. If the optimization succeeds by finding a solution
that works within the set ranges, but does not meet the target
values exactly, the error represents the combined error of all of
the specifications.
Note
The RMS error reflects only those
g
oals that are
enabled. The error does not include contributions
from constraints, nor does it reflect any
specifications that are disabled.
