Hello community, 

 

I am working with different ibis model of STM32H7, however, this is the only one that's giving me an error in my Altium Designer – could you have a look at it?

 

The file is stm32h723_730_733_lqfp144.ibs

 

Kind regards,

Javier.

Hi, thanks a lot for your suggestion and for taking the time to help.

In the end, I managed to resolve the issue, but it turned out to be unrelated to the IBIS model or the Altium import tool. The root cause was actually somewhere else in the setup.

Hello @JavierGonzalez and welcome to the community;

 

I don't think there's a problem with Ibis; rather, it's the Altium import tool. Usually, the models are tested with HyperLynx, please look at AN4803.

To solve the Altium issue, I recommend you to limit the length of reference names to 62 characters or fewer.

 

I hope this help you to solve the issue.

 

Thank you.
