Today I received a question where the user was looking for an Integrator block with variable upper and lower limits that could be specified from signals. I was happy to simply answer: There's a solution for that!

In order to help users finding the information they need, we have a bank of technical solutions published on our website. These solutions are created by technical support engineers when they answer a question. If they think that someone else in the world might have a similar questions, they publish it.

So I went to the support section of our website and searched for variable limits integrator:

The first result I found is the following solution:

How can I create an Integrator block with variable limits in Simulink?

When looking at the details, I realized that I created this solution myself a few years ago, not long after I joined MathWorks. It uses the state port of the Integrator block with a few Logical Operator and Relational Operator blocks to make an integrator with variable limits:
