I have a simulink model that I copied from another model. I did some changes and when I run the model, the broken chain appears in the powerGUI block and it says "Disabled library link: powerlib/powergui". Model works though (much slower than the original model). No error happens when this link is disabled. I can then either run it again disabled or restore the link and run it but after compiling it disables the link again.
How can I prevent this from happening? Should I worry about this? Is this the reason why my model is much slower than the original one?
Note: When running the model without the powergui, error comes up notifiying that this block is required.
