Hi, I need to implement a timer in simulink. The timer will have a square wave signal at its input with varying pulse width. What I want is, it should save the data in workspace in a 2-D Array format, with first column showing number of pulses and second column containing the respective time duration of the pulse. How can I implement it?

It might be easier if done in MATLAB. You want the result in MATLAB base workspace anyway. a is your input pulse, Out is the result, here time is assumed to be 1,2,3,...
a=[0 0 1 1 0 1 1 1 1 1 0 0 1 1 1 0];
df=diff([0 a 0]);
b=find(df==1);
c=find(df==-1);
e=c-b;
Out=[b;e]';

Then the code in my answer provided the solution, right? Right now, the first column is the time stamp of the rising edge. If you want the count of the pulse, change the last line to be: Out=[1:length(b);e]'
