SM320C6701 IBIS Simulation

Other Parts Discussed in Thread: SM320C6701, TMS320C6701

For the SM320C6701 IBIS model c6701cer.ibs I am missing Signal SDCLK.

Signal exists for TMS320C6701(sprm019.ibs) model but this DSP has a different housing. What CLK signal shall I use for the IBIS Simulation instead?

    Alexander,

    This is an older  model, and I cannot comment on why this signal is missing.

    However, you can look at the sprm019, and see that SDCLK is using the macro UOT212.

    Any signal in the CER IBIS using the UOT212 macro will yield similar results.

    I can request package parasitics for this pin.  However, this may take some time, or is not possible due to age of the package models.

    It would be reasonable to use a pin that is near the same position on package.

    Since SDCLK is pin T9, I would recommend using T14 (INUM1).  This should have very similar parasitics as T9, and uses same macro model.

    Regards,
