the PSpice Optimizer
To compute standard component values based
on the most recent optimization
1
From the Edit menu, select Round Calculated.
The PSpice Optimizer replaces the parameter values with
the standardized values only if the new values remain within
the specified limits. If so, the optimizer automatically
calculates new performance values (based on derivative
data) using the new parameter values, and displays an ‘
e’ in
the upper right-hand corner of each specifications area to
indicate that the performance measure is an estimate.

Results
Performance results are not written to the optimization file until
you deliberately initiate a save operation.
To save optimization results to the current
optimization file
1
From the File menu, select Save.
By default, the PSpice Optimizer writes the results and the
latest optimization settings to a file named
design_name .opt. If you started your design from a
schematic, this file already exists. If not, the optimizer
displays the Save As dialog box and you must enter the
name of a new file.
To save optimization results to a new or different
file
1
From the File menu, select Save As.
2
Enter a new file name.
3
Click OK.
If an optimization file with this name already exists, the
PSpice Optimizer requests confirmation to overwrite the
file.
