altuim designer signal integrity

how to put pin in high impedance state ???

whenever the circuit in action :

1st stage : 74hc541(1) well be output and well address M27256 , the 74hc541(2) well be in z-state .
2nd stage : 74hc541(2) well be output and well address M27256 , the 74hc541(1) well be in z-state .

for example if we look at net1 in the illustration

74hc541(1) pin 18 is output
74hc541(2) pin 18 is z-state
M27256 pin 3 is input

i just want to configure altium signal integrity pin direction to simulate the pin direction as Z-state or exclude the pin from check.

altium just has tri/in and tri/out for Hiz pin model .

any idea

thanks

To be honest, I never used the SI feature of Altium before but I think you already have your answer

Technically, both terms HIGHZ and 3-State, depending on the context mean the same thing:
