How to increment a value every second with periodic resets to zero in Simulink?

I need to simulate a 'Heartbeat' function in Simulink, create an input variable x with value starting from 0, then increment x by 1 every second, simutaneously output a variable y every second, which is equal to x . Once x reaches 100, reset x to zero and repeat the increment cycle. How to program 'MATLAB Function' block with input x and output y to realize the 'Heartbeat' function? Or any other ways?
