PROCESSOR-SDK-AM64X: IBIS Model Available?

Hello Charles

Thank you for the query.

Did you look for the IBIS mode on the product folder as below

https://www.ti.com/product/AM6442#design-development

We also have an FAQ that provides links to the key collaterals

Hello Sreenivasa,

I looked through those links, and I could not find the IBIS model information that I need, which is:

[Model]        gpio6x

[Ramp]

R_load = 50.00Ohm

|                   typ                 min                 max

|

dV/dt_r     759.567mV/608.821ps 569.138mV/780.708ps    1.099V/248.460ps

dV/dt_f     972.056mV/433.631ps 779.354mV/655.279ps    1.437V/233.958ps

This data (along with the model assignment to pins) is in the IBIS mode. The R_load gives me the impedance and the dt_r and dt_f gives me the rise and fall times.  I use this data in formulas to calculate the full range of constraints for high-speed signals/interfaces.

I noticed that one of the documents has some references to IBIS models from Cadence, but it doesn’t have the specific data I need. 

Does TI provide IBIS models? If not, do you know where I could find them for any of the AM64x processors?

Thank you,

Charles

Hello Charles

Thank you.

Please refer to the model that we provide to customer.

Could you help me understand if you downloaded the model and you are not able to find the information you are looking for?

if yes, i need more information on what type of model you are looking for.
