TMS320C6655: IBIS model

Hi Kyle, 

Thanks but I'm not sure I understand what you sent me here. The link you gave me here leads to a page where I can download two exe files: 

KeyStoneISerDesIBISAMIModels-1.0-windows-installer.exe

MatlabRunTimeCompiler-v7p9-windows-installer.exe

I need ibis files and not exe files. 

Thanks, 

Ohad

Ohad,

This is the IBIS model:

TMS320C6655/57 CYP IBIS Model (revision 1.2)

The EXE you point to is an installer for IBIS AMI.

Regards,
Kyle

Hi Kyle, 

I'm now trying to assign that ibis model o the Sigrity Aurora SW and it seems to be mismatched - I get an error that the ibis is not ok. 

Could you tell what is the error with that ? 

Or at least send me an updated correct file. 

Hello Ohad,

What is the exact error that you are seeing.  Note that the IBIS model includes this text:

That is the error I get whenever I try to load the Ibis file for the DSP. 

I don't see that error with all other ibis models for other devices.

Hello Ohad,  

That error is not very helpful.  We double checked and are able to load/run a simulation using the IBIS file successfully using Hyperlynx simulator.  Can you check with your tool vendor on what the issue might be?

Regards,

Kyle
