  • Input power of a subcircuit

    Hi, I'm simulating with an envlp + pss simulation a rectifier and I would like to estimate the power that goes in input to a subcircuit that implements it. The input voltage of the subcircuit is constant and the current is given by a constant plus an alternating contribution. I tried the following...

  • Re: OCEAN simulation used for envlp analysis

    Thanks for your answer! The version of icfb is 5.1.0, the sub-version 5.10.41.500.5.96! If I generate the netlist in an OCEAN script, in the file input.scs there is not the clockname, as shown in the following lines: " envlp envlp harms=1 stop=200u errpreset=conservative readic="enc.fc"...

  • OCEAN simulation used for envlp analysis

    Hi, I have a problem executing envlp analysis through OCEAN scripts. If I try to execute the simulation with the graphic interface, all is ok, but saving the script and executing it, an error stops the envlp simulation. The error is: " Error found by spectre during envelope following analysis `envlp'...

  • Re: How to plot device parameters from transient sims.

    Hi haiko, Thank you for your response. Unfortunately it does not answer my question. Let me try to be more specific: I already know how to open results, view and plot voltages and currents in ocean and analog artist. I want to plot the small signal parameters of the BSIM4 model of some transistors during...

  • How to plot device parameters from transient sims.

    Hello, I would like to plot gm, gds, cgs, cgd, etc. as a function of time in my spectre transient sims using analog artist. How do I do this? Thanks, Eric.
