  • How to not netlist a certain symbol

    Good day! I want to make library that when added to schematic, the instances are not netlisted during spectre simulation. The symbols does not have models and are designed for CDF parameter extraction only. I have a reference LIBRARY with this property but I can not find out how it was implemented. I...

  • Change CDF variables from inside an Ocean script

    I generated an Ocean script from Analog Design Environment | Session | Save Ocean Script. I've been able to run some simulations using this script. But my schematic has a few instances with the same cdf parameter. For example, an inverter has a width and length associated with it. I have multiple...

  • netlist pin order for LVS

    Hi, I'm trying to change the order in which a circuit is netlisted for LVS but I got into problems. I've modified the termOrder in the CDF form accoding to the pin order I want and I've place the following line in ~/.simrc (and also in my cadence working dir): auCdlCDFPinCntrl=t I've...

  • Modify netlist of a block and resimulate (CDL.... CDF....)

    Hello everyone, I am trying to pinpoint a layout error mechanism by modifying the av_extracred view netlist and resimulating the testbench. I have managed to create a manually written netlist as a spectre view before by following this tutorial: http://www.cadence.com/Community/blogs/rf/archive/2009/01...

  • Reading a parametrized cdf parameter

    Hi, I am trying to read the CDF parameters of a FET. My problem is that some of them refer to other CDF parameters via iPar(). So if I do: p1=cdfGetInstCDF(inst)~>parameters v1=car(parameters)~>value Then I get v1="iPar("\width\")", instead of the numerical value. This is fair...

  • CDF data structure 'flattened'

    I have been writing some skill code to extract information from a cell's cdf - but I see a mismatch between the docs and the way some information is stored in the skill code - it seems the simInfo part has all of it's data 'flattened' into a string, and I cannot access the parameters...

  • SKILL expression for CDF display property

    I'm trying to create a function to set whether one of the CDF parameter should show up based on the value of another CDF parameter but I'm not sure how to do that. Can someone point me to the right direction? I tried using iPar but it doesn't work... Say I have two parameter A and B. What...
