How to use Flash core cell models

KaniKune

Hello, I'm quite new to use Ultrasim and I'm confused how to take flash core cell model into my test bench.

I produce netlist with Virtuoso GUI which includes transistors I'd like to treat like FG-transistors.

do I use these .appendmodel.. and .model commands in the test bench or should I manipulate produced netlist?

Short example would be awesome.

Thanks, Karri

  • Hi Karri,

    If you're trying to reference your model files, that would just be by using Setup->Model Libraries in the Analog Design Environment, and then specifying the files containing the models. These would then be included.

  • Hi,

     I am able to reference my PDK components, but if I've understood correctly, Ultrasim 7.0.1.076 that I'm using supports "flash core cell" feature, where transistors are treated like they have floating gate. I'm trying to utilize this feature but I'm uncertain where to add these lines which active the feature.

  • There's a chapter on this in the UltraSim documentation (in MMSIM72, it's called "Flash Core Cell Models", Chapter 15) which goes into this in more detail. Have you read it?

    Regards,

    Andrew.
