Hello,

I want to write a simulink function that returns the index of a specific current simulation time.

For example: let's say I have a total simulation time of 3000 I want a function when simulation time reaches 300 to tell me how many time steps have passed.

Do you want to do this after the sim is complete or while the sim is running?

One way to do this is to put a step counter in the block. This will keep track of the number of times the block is executed. This way, you get the right number of steps, even if the model is using a variable timestep.
