Simulink modeling solution needed

Hi

I got struck in one of the simulink model design. prob is like this.... I get some series of constant values from a signal, it will be compared with some constant[for ex. 1.1]. if true, a counter is decremented[first initialized to zero] and that counter value is compared with 2nd threshold value[for ex. -10]. if threshold is reached i.e -10 or more, i need to reset the whole set up to 0 starting from decrement counter.

all the design should be done in simulink only. thanks in advance

Use the "Discrete-Time Integrator" block from library Simulink>Discrete. It has an option to allow external reset.

Use the "Compare to Constant" block to compare your signal with a constant. Also, use the same block to compare the counter with -10 and then trigger the reset of the Integrator.

Or use a Unit Delay block, start off with this demo model, rtwdemo_counter.mdl.

what if the signal is a series of constant numbers. ?

It will be same.
