Running Pole-Zero Analysis in Interactive Mode
In interactive mode, the pole-zero analysis prompts for user input as it runs, enabling the
accurate specification of its input parameters.
Prerequisites
An AC analysis must have been run on the circuit of interest, and that analysis must have
included a .PZ command (to generate a .pz file in the output directory.
Procedure
1. Navigate to the directory containing the output .pz file from the AC analysis.
2. Run:
pz .pz
3. The pole-zero post-processor runs. When prompted, enter arguments for the following:
• -th value
Threshold for pole/zero cancellation
• -cutoff value
Cutoff frequency
• -pindices indice_list -endpindices
List of indexes for pole selection; indices must be in increasing order
• -zindices indice_list -endzindices
List of indexes for zero selection; indices must be in increasing order
The pole-zero processor runs to completion.
Note
Any prompts for which an argument is not provided will take the default answer—
that is, the same as for the -batch mode.
