IC validation board design suggestion

Ashutosh Nahar

Hi,

Any one can please suggest me the guideline/suggestions regarding IC validation board design?
The board need to have RGMII, RMII, SPI and USB etc.

I want to keep all provision on the board so that it should be not mistake after tape out .

Thanks
Ashutosh

    Hi Ashutosh,

    If you are building an IC board for evaluation, it is important to provide all the provisions to test each of the pins for the IC you are testing and create easy ways to change pin settings. In addition, if you are testing for certain protocols, there must be an convenient way for you to access the signal lines with your test equipment, so the types of connectors you use (for example, header pins, SMAs, or cages for plug-in modules like a USB receptacle). Lastly, you should optimize the board layout, especially if it is for high-speed protocols, so that you can determine the most accurate representation of the IC's performance as opposed to degradation that is potentially affiliated with sub-optimal board design.

    Which device are you validating? Typically we have EVMs available on TI.com to evaluate our ICs, along with User's Guides for guidance.to validate the IC.

    Thanks,

    Michael

    hi Michel ,

    Thanks for your reply.

    Actually we need to validate the SoC. For that purpose we are making one board.
    I want to ask you further that if my soc have GPIO pins (one particular bank) which either i can use as RMII or RGMII or SPI .
    So how i need to design board? Should i use 2-3 mux so that I can able to connect each end design for each interface or Should I create One particular board for one particular interface.

    Till now, I never designed Validation board so your experience help a lot.

    Thanks
