Plotting pole/zero results

Grover
Grover over 15 years ago

I often use the pole/zero analysis in Virtuoso GXL (6.1.3), and it works great, but the way to plot the poles and zeros is quite inconvenient. After each simulation, I have to click somewhere in the Results tab, select "Direct plot -> Main form", click "pz", set options, and click "Plot" before the results appear.

Obviously, it's quite annoying to do all this after each simulation run, while the normal AC analysis just pops right up. Is there a way to make the pole/zero plot appear automatically?

(perhaps equally annoying, is that Virtuoso also always opens another copy of my schematic. I usually work with ADE in one window and the schematic in another, but when I click "Main form", it opens another copy of the schematic in a new tab in ADE. Is there a way to stop this? This also happens when I choose "Print", e.g. for a pole/zero list or detailed operating points.)

    Wow, thanks! This makes my life a lot easier :-)

    But still, do you have a solution for the second issue I mentioned? Now that I can automatically plot poles and zeros this is less important, but it still happens when I want to check e.g. the detailed operating point. Is it because I have one window with ADE and another with Schematic, and they are not aware of each other?
