How can I acquire waveform expression using a trace in ViVA?

Reinice

Hi All,

Good Day. I 'am trying to get the information from a selected trace on the graph. For example I have a trace AVDD and when I send "/AVDD" to a calculator, it's equivalent expression is value(getData(“/AVDD” ?result “tran”) “Cload” 2e-12) as shown in the buffer part of the calculator GUI. How can I acquire value(getData(“/AVDD” ?result “tran”) “Cload” 2e-12) using a trace(ex. "/AVDD") to get this information using SKILL?

My main goal is how can I acquire "value(getData(“/AVDD” ?result “tran”) “Cload” 2e-12)" after or during an analysis executes and/or finishes using SKILL and/or OCEAN?

btw, I want to do this in batch mode(ocean session).

Thanks and Regards,

Reinice

  • Reinice,

    I think I already explained that there's no way to get an expression from a selected waveform other than sending it to the calculator - i.e. there's no SKILL API to get the expressions from a window or the selected waveforms.

    You can use the expression in a script though. I still don't think I entirely understand what you're trying to do or why the expression doesn't work for you.

    Regards,

    Andrew.
