Creating parametric diagram

[DesperEAdo]

I would like to create a parametric diagram in order to calculate system perfomance indicators. In my example processing time. What I have done so far:

On a BDD I've created a block "Software" with a composition relationship to 3 subparts. Software owns a value property with the maximum processing time and each of the 3 subparts own a value property for the individual processing time. The block software has a composition relationship to 2 contraint blocks. One sums up the processing time the other checks if the maximum processing time is exeeded. Both contraint blocks own the contraint parameters and the contraint expression in OCL.

Now I want to create a parametric diagram by connecting the value properties from "Software" and it's subpart to the constraint properties. With the EA function "sychronize structural elements" it is possible to show up the constraints but without parameter ports. Unfortunately it is not possible to add the block's values to the parametric diagram.

Any idea how to proceed?
