Problem in using stm32h IBIS model

Hello everyone,

I am facing issues while performing Signal Integrity analysis using STM32h IBIS model.

Currently i am analysing Signal Integrity for I2C signals where i am configuring my MCU I2C signal levels to 3.3V, but when simulated i am getting 2.4V at the I2C pins.

If i perform the same test by configuring my MCU I2C signal levels to 1.8V, i am getting 1.8V at the I2C pins.

Can anyone help me out in solving this problem.

Model used for the analysis is attached below. I am using stm32h743_753_tfbga100.ibs.
