    Hi, this post isin reference to http://www.cadence.com/community/forums/T/14022.aspx , where i described problems concerning an inductor that had been automatically generated by VPCD tool. Defining the layout of the inductor as a blackBox does not solve the problem, for assura does not recognize pins...

  • How to modify a automatically generated instance.

    Hi, After inductor cell generation (done with Passive Component Designer - PSD) I made DRC check, that found errors in the layout schematic. The problem is that some vias are placed too near to the edge of the polysilicon Patterned Ground Shield - PGD. I tried to remove the vias or correct the layout...

  • Assura Foundry Support

    I've been blogging a lot about Assura recently, so I thought I would continue by talking about rule decks. Inside Cadence, we maintain a database that shows which foundries support which process for which products. This means that we can quickly give you an answer if you are considering using a new...

  • Assura On Steroids

    In a recent post , I hinted at a significant performance improvement in Assura . Our R&D team focused on performance improvements in the 3.2 release, which was shipped last August. Based on our suite of performance benchmarks, we achieved an overall 10x performance boost. This comes from two fundamental...

  • ERC in Assura II

    In my last post I talked about the layout, schematic and netlist ERC capabilities of Assura. "But", I hear you ask, "is it programmable?" One of the characteristics that makes Assura such a natural fit within the Virtuoso custom design platform is that it shares the platform's...

  • ERC in Assura

    A few customers have recently asked whether we can provide schematic-based ERC checks. This is no doubt spurred by a recent product announcement by one of our competitors. No - I'm not going to say who, and I'm not going to provide a link to their product page. We have had layout-based ERC checks...
