Hi Sudha,

We do not have a spice model available for this device. What do you want to simulate here? If it is just the arethmetic functionality, then you can use the Controlled Source Wizard to implement this.

You can find more details in this video on how to do this: training.ti.com/how-use-controlled-source-wizard-tina-titm-simulator

Hi Nikhil, I cannot find the MPY100 or MPY634 in the link you provide here. Can you help provide a link to get the TINA model of this device? If you cannot find one, can you help provide some method how to use the Controlled Source Wizard to implement this? Thank you very much.

I also have the same request.

Thanks and regards,

I need to add the MPY634 into my library. If you can send me the link for the same, that is highly appreciated.

Hi Charles,

You can use the controlled source wizard to implement arbitrary functions using voltages and currents. Please refer to the following video for details. You can use this to implement the basic functionality of these ICs.

Hi Sudha,

I was able to dig up an old macro model for the MPY364 that we created a few years ago, you can find the original thread here e2e.ti.com/.../438832 . As Nikhil mentioned, it's built using controlled sources so feel free to modify, customize it and expand it to MPY100. I have attached the macro model and a test bench from the thread.MPY634_TB.TSC

Dear Sir/Madam,

I have this multiplier from a circuit. I would like to know how to add this to the library so that when I search for the multiplier, I should retrieve it.

Thank you in advance.

Regards,

Hi Sudha,

Your attachment did not come through. Can you attach it again. I would just create a folder structure on your local computer and store the TSM/TSC files in the structure. In order to insert a TSM file, use the Insert >> Macro functionality. For TSC, just double click on the TSC file to open it in TINA-TI.
