MAX-10 IBIS model issue

Hello team, I am working on IBIS model validation of MAX10 I have observed that the temperature ranges in IBIS file for CMOS and TTL models are same. Ideally, For CMOS temperature which causes th...

Hi,


I think your opinion is right on the different I-V characteristic of TTL and CMOS under different temperature.

However, IBIS model of FPGA is just a behavior model, showing I/O I-V characteristic. You can treat it as a black box, not mean there is real CMOS or TTL component. So it does not totally follow TTL and CMOS characteristics under different temperature.

Also, you can refer to this article: How do IBIS models relate to device speed grades? (intel.com)
