The new simulation tool also comes with a couple of new interactive simulation experiments. The first one to be described here is the Signal injection plug-in as seen below.
It couldn’t be simpler to use. Simply load the model you want to experiment with, click the ‘add signal’ button, and choose parameter and signal type. Immediately the signal will be displayed in the graphing window and can be moved about with the mouse allowing you to directly see the influence this has.
For the sine (or square wave) signal type it is possible to change the angular frequency by holding down the CTRL key and moving the mouse.
Here a video demonstrating this feature:
