Hi Hojae,
I believe the block that you are looking for is "Clock" or "Digital Clock" where the output of the block is the current simulation time. The primary difference between the two blocks is that the "Digital Clock" block outputs the current simulation time at a rate that is specified by the user whereas the "Clock" block results in a continuous output. In your application, I believe you require the block to output the current simulation time at the rate of 0.1. The following are the documentation links for both the blocks:
The figure below shows the output of both the blocks:
I hope this addresses your question.
