[Simulink] I want to just switch two values with positive trigger

Hi,

I want to make a simple Simulink model, switching two values with positive trigger, as shown below.

How can I make it? I tried many things, but I could not.

# I want to use only HDL-compatible block.

Best,

Use the trig signal to trig a "triggered subsystem", the trigger type is "rising". Inside the subsystem is a "Not" logical block. Outside, feed the subsystem output to a "Unit Delay" block and then feed it to the input of the subsystem. Set the inital of "Unit Dela" to be 0.

All blocks are from HDL library.
