Parameter name vs ID in expressions

[Khushi]

Hello

I have an element dependent on some parameter then do I need to use the parameter name or id in the dependency expression.

For example, I have a parameter WIDTH 

<ipxact:parameter parameterId="WIDTH_ID" resolve="user" type="int">
<ipxact:name>WIDTH</ipxact:name>
<ipxact:value>8</ipxact:value>
</ipxact:parameter>
and one of the port left dimension depends on this parameter should I use the parameter name or id in the expression ?

<ipxact:vector>
<ipxact:left>WIDTH-1</ipxact:left>
<ipxact:right>0</ipxact:right>
</ipxact:vector>
 

or

<ipxact:vector>
<ipxact:left>WIDTH_ID-1</ipxact:left>
<ipxact:right>0</ipxact:right>
</ipxact:vector>

Which one is correct ?

Thank you

Your second case is correct. Always the parameterId. You can obviously make the parameterId the same as the name. On the other extreme, some editors, like kactus2, use UUIDs for the parameterId but always show the parameter name in the UI to abstract away the ID referencing details.
