TINA/Spice: simulate flip flop model with TINA

Other Parts Discussed in Thread: TINA-TI, SN74HC574, SN74LV574A

Tool/software: TINA-TI or Spice Models

Hello,

I'd like to use TINA to simulate a D Flip Flop (as SN74HC574) but I don't find this model on TI website.

Is it possible to implement a D Flip Flop model in TINA ?

If no, is there any other simulator that can do this job ?

Thanks for your help and have a nice day,

Regards.

    Matt,

    To request a Spice model for the SN74HC574 please contact your local TI Sales rep or Field Engineer and they can submit a model request for you.

    The free version of TINA available on the TI website does not have built-in D flip-flop model.
    The TINA vendor - DesignSoft - offers versions of TINA that do have a D flip-flop model.
    You could check with them to see if those simulators would fit your needs.

    Regards,
    John

    Hello John,

    Thanks for your fast answer.
    Is there any other spice model for TINA available directly on TI website ?
    I found an alternative part: SN74LV574A which is also a D Flip Flop.

    There is a model (check below)
    Title Category Type Size (KB) Date Views
    SN74LV574A IBIS Model (Rev. B) IBIS Model (Multiple Files) 15 May 2003 8 views

    It seems that the link is not working anymore. Is it possible to use this model in TINA ?

    Thanks a lot for your support,

    Regards.

    Matt,
    Unfortunately TINA does not support IBIS models.
    IBIS models are behavioral models of the device input and output pins. They are not compatible with Spice simulators.

    We don't traditionally provide Spice models of digital parts because Spice is at heart an analog simulator and it isn't an efficient tool to use for digital simulations.
    Having said that, there have been a few exceptions in the past, so to request a model, please contact your local TI sales rep or field engineer and they can submit a model request on your behalf.
    Regards,
    John
