  • IBIS model simulation

    I am designing a Data acquisition system with a Texas instruments ADC, Inamps and a ST micro electronics micro controller. I am getting spice models for my inamps, differential amplifiers etc. so that I could do SPICE simulation. I wish to see the output of my ADC if I am providing an input signal with...

  • Is it possible to parameterize a Multi Bit wire with vector expressions?

    Is it possible to parameterize a Multi Bit wire with vector expressions? Also can you parameterize the number of instances in a instance defines with an iterative expressiion? I'm trying to create a schematic that you can reconfigure the number of internal devices via a parameter.

  • Complex wire labels with iterated instances

    Hi all, I'm working with the CIW version 5.10.41 and came across with the following problem when doing schematics (Virtuoso schematic composer) for a full custom mixed signal design: Let's assume that I have a 3 bit bus going into an instance (I), and I need 8 of these instances all together...

  • Thing You Didn't Know About Virtuoso: Redux

    After a long break, I'm going to try to venture back into the blogosphere, starting off nice and easy--by cheating... You see, Virtuoso IC 6.1.5 came out at the end of January, and one of the changes made to the Schematic Editor is that many of the handy dockable assistants featured in IC 6.1 are...

  • Problems Importing OA Design from Virtuoso into Encounter

    Hello, While trying to perform place and route using Encounter I'm "encountering" errors importing my design from Virtuoso. When I try to import the design, I get the following: Reading tech data from OA Library 'NCL' ... FE units: 0.001 microns/dbu, OA units: 0.001 microns/dbu...

  • Using OA for netlisting

    Hello, I want to use OpenAccess to do my own netlisting. Accessing connectivity data is no problem. Is there a way to access CDF information like attribute mapping, port sequencing and model type ? Regards
