    Spectre has a pole-zero analysis. I don't know if it is in 4.4.5 however.

  3. pz is new in IC5033.

    Are there application notes on using spectre PZ with ocean (or aptivia etc...) to do root-loci ?

    You can use pzPlot() in OCEAN. I think it gives an error however:
    32720266 Closed P1:687146 - Warning if pzPlot is used in calculator

    \o *Error* Expression pzPlot(?plot 'zeros
    ?freqfilter 1e+10) evaluated
    \o to t.

    I have also requested a pz button in the calculator:
    32715568 Closed P2:686834 - Want pz button in calculator

    Both are set to backlog.
