MAX 10 IBIS model

Hello all,

I am working on Intel MAX 10 FPGA ibis model,

model name -lvttl_rio_d4s2

I am unable to find Timing specifications for this 3.3V LVTTL model in datasheet ,

For simulation purpose I need rise and fall time of this model

Can someone please guide me, where would I find more details regarding that.

Thank you,

Shweta

    Hi,

    ​

    MAX 10 datasheet contains the following information about I/O Timing in Table 58, which may be helpful to you.

    Best Regards,

    Mengzhe

      Hello Mengzhe,


      Actually, we were searching for rise time and fall time specifically. we also went through the whole document but didn't get anythin related to this specific model number. (model name -lvttl_rio_d4s2)

      It would be a great help if we get the fall and rise time for 3.3LVTTL.

      Best Reagards,

      Shweta

    Hello,
    IBIS file has rising and falling waveforms, unfortunately only with 50 ohm load.
