We are pleased to announce that SystemVision Cloud now supports import of SPICE subcircuits and individual .model statements as a way to specify a model for use in SystemVision.  Simply choose the Create New Component > From SPICE menu when you are editing a design.
Watch this short video to see a demonstration.

This new capability gives you a convenient new way to leverage SPICE models that are available from many component suppliers.  Here is an example of an Infineon LED driver component test circuit, as seen in the above video:

Disclaimer: Please note that this facility is focused on "standard" SPICE formats and does not attempt to provide support and/or compatibility for several proprietary constructs found in some PSpice® or LTspice® models.  You will see best results from models that are targeted at the generic subset of SPICE formats.

Proprietary Infringement?

If I create a new model, say, by copying the Spice net list from a manufacturer's datasheet, am I sure to be protected from any IP infringement claims?


You are responsible for content that you post, including any content that might infringe someone's IP.  

Data posted on manufacturer websites, however, is typically provided to the public for the purpose of making use of the manufacturer's parts, so IP issues are usually not a problem.  If in doubt, contact the manufacturer.

downloading models from the cloud

I work for a company that has SystemVision, can I download models from the cloud that don't seem to be in my current systemvision library or can I request the models from Mentor.  How do I get some of the new models found in systemvision cloud that are not in my library.

You can just copy/paste all of our open-source models ...

That may be the easiet way for you to include SystemVision Cloud models into SystemVision Desktop, for now. We are working on a better mechanism for this. But for now you can simply:

  1. In SystemVision Cloud, right-click on a model either on a schematic or in the component browser, and choose "View/Copy Model"
  2. Select all of the VHDL-AMS text and copy it
  3. Open a simple text editor on your computer and paste it there. Save the file with the same name as the model entity: "model_entity_name.vhd"
  4. On some versions of SystemVision Desktop, you can just drag and drop this file icon onto an open schematic and it will create a new symbol, and place that model into your project .hdl directory. Alternatively, you can use any method you currently use to add models to your SystemVision Desktop libraries.

Hope that helps.


Import Your SystemVision Cloud Design Into DxDesigner

Perhaps a more convenient way for you to access these libraries is to use the import tool.  See this blog for details.

Import Your SystemVision Cloud Design Into The PADS PCB Environment

This describes how to use this import tool for PADS, but it works for any version of DxDesigner that is able to run scripts.  The downloading of this tool automatically installs the latest version of the online model libraries, any custom models that you have created online (either as VHDL-AMS code or using the datasheet tools), and sets everything up for you to simulate locally with SystemVision desktop.

Let us know if you have any difficulties!
