Diva Extract

archive

Hi All, I'm a university student currently learning to use Cadence Tools.I'm trying to write Extract Rules for Diva - just for the parasitc resistances and capacitances.So I thought that the measureResistance command will be enough...but it just takes out the resistances without connecting them and for the capacitances- I wanted to use the multiLevelParasitic command (before that I've defined the outLayer for the measureResistance) but there are no capacitances in the extracted view... I'm sorry if the question is stupid but I'm learning this since 2 months and I don't have much time left to finish this project... Thank you in advance Best regards kremi

  • If you read the documentation on Diva (/doc/divaref/divaref.pdf if you can't find it in cdsdoc), this is quite clearly described in the documentation for measureResistance, particularly in the section "Cross Coupling and Fringe Capacitance" in the "Extracting Parasitic Resistance (PRE)" chapter.

    You simply specify an output layer for the measureResistance command, and then use these as the inputs to multiLevelParasitic instead of the original layers - that way multiLevelParasitic knows about the resistance information and how the layer has been split up to accommodate the resistors.

    Regards,

    Andrew.
