h7 ibis file correctness

Hi

can you please check the stm32h743_753_lqfp100.ibs model from the en.stm32h7_ibis.zip archive? I have a problems simulating SI on the rmii interface, most likely because of this output model: io8_i2c_ft.

Right now there is only two ic with direct rmii connection in the simulation and only pin 47 (PB11, io8_i2c_ft_3v3) outputs the absolutly horrible signal. On the other side of rmii is only ksz8081rnb (with correct ibis model)

io8_i2c_ft_3v3

Any other outputs

Please help, you my only hope)

I found another thread with kinda same problem, like i2c, lower output voltage... Problem was fixed with correct ibis file he has provided.

Can you give me a good one too?
