Simulation By changing input parameters is not working

[kanurusubhash]

In D- Latch, D-Flip Flop Positive Edge Triggered and D-Flip Flop Negative Edge Triggered experiments on changing the input variables simulation graph is not changing accordingly.

Steps to reproduce:

1. Click(Mouse right click or left click) on the Input component D that is added
2. A popup gets displayed with variable parameters Min Volt, Max Volt, Step Size, Raise time, Fall time, Total time
3. Change any of the parameters and click on OK button.
4. Click on the Simulate button to generate a new graph

Current Result:
No change in the output simulation graph

Expected Result:
A new simulation graph corresponding to changes in the input should be displayed in simulation region.
