I am trying to implement a Repeating Sequence block that can be reset to its initial state based on a condition. I've attempted to use a Resettable Subsystem as this works with a Sample Based Pulse Generator, but it does not provide the same behavior for the Repeating Sequence. Anyone have any possible solutions? I need to be able to create a signal that can repeatedly ramp up and ramp down, but only start and be reset when a given condition is met, which is why I gravitated towards the Repeating Sequence block.

If you look inside the mask of the "Repeating Sequence" block, you will see it is built on top of the 1-D lookup table.
To achieve what you want, you can use an Integrator block with external reset. The input is 1 so the output is basically the simulation time t. The output is reset by
  1. The output is great or equal to the period of your repeating sequence, or
  2. Whatever condition you desire
Feed this output to a 1-D lookup table, where you specify your repeating sequence data.

Adjusted the fixed step size and it solved the problem, thank you!
