How to show the Unit parameter in the signal attrbutes of a constant block?

For the attached Simulink model I created using MATLAB R2021a, how can I show the Unit parameter in the block parameters of the constant block?

There is no "unit" property at the Constant block. What you can do is to define a Simulink parameter object.

A=Simulink.Parameter
A.Value=1
A.Unit='m'

And then in your Simulink model, specify the value of the Constant block as A and you can display "Port Units" in Simulink.

So, how can I have a window like this

Is there a replacement block for a constant block that automatically has a units parameter internally?

And does your solution allow for the unit conversion block to work?

[Fangjun Jiang]

The Inport and Outport block support built-in unit specification. Once both sides have the unit specification, I think the Unit Conversion block can be applied to convert them automatically.
