Which model in an ibis model file should I use?

Currently I am trying to use ibis model for simulation. I found ibis model file provided by STMicro and try to use them. But I could not figure out which model pointed by model selector I should use.

For example, there are 24 candidates of the model for PA0. But I don't know which one for my project.

Actual .ibs files is like below.

Thanks.

[Pin] signal_name     model_name      R_pin   L_pin   C_pin

...

6 PA0 io8p_wsudq_ls_ft_v33 61.160E-3 1.8629E-9 10.243E-15

    Hello,

    Actually the choice of the needed submodel depends on your use case. Below you can find some clarifications about the models:

    IO speed: speed00: low speed, speed01: medium, speed10: high, speed11: very high

    pd: pull down, pu: pull up

    Best regards,

    Thank you for your help. You helped me a lot and solve what I could not understand. I thought the electricity property should depend on actual setting on MCU and I didn't know what "SPEED" or "PD" mean. ​
