Hi,

Does anyone has MSP430F2418 IBIS Model?

Thanks!

    Unfortunately there are no hardware simulation models available for the MSP430. IBIS models are only used for signal integrity simulation on signal lines (termination etc.). Because MSP430 outputs are relatively slow, IBIS files will not help much and we do not have any data on this. IBIS is mainly used for signal simulations on high speed back plane bus systems.

    Just checking to see if things have changed.  Are there are IBIS models available for the MSP430 family?

    Brandon,

    One reason to create IBIS for the MSP430 would be to assist in determining the required input protection circuitry.

    IBIS helps because it shows the I-V curve for the protection diodes as you go above VDD and below VSS.

    Spec says you need to limit current to < 2mA,  so if you're switching a 12V input you need to factor this into the voltage divider.

    Where would I find the IBIS model for MSP430F5508IZQE device?

    By Brandon's logic, this part should have an IBIS model because it has high-speed I/O - namely USB 2.0 controller.

    I find it ill-advised that TI would suggest to someone to not simulate critical nets on when doing a layout. And it is short-sighted to assume that an MSP430 might not be part of a larger complex system that might interact with critical routes.

    All digital parts supplied by an IC manufacturer should have a simulation model. Let the user decide if they need it or not!
