How do I make a user-defined square wave generator in simulink model?

I want to make a user defined square wave generator for simulink model( instead of using pulse generator).

But I don't know which formula should I use. I am asking for help.

Thanks in advance.

Hi @Rakib

Perhaps you can try this one:

tau = 20;           % period of the square wave
Ts = tau/(2^10);    % 2^10 samples per period
[u, t] = gensig('square', tau, 2*tau, Ts);

plot(t, u, 'linewidth', 1.5), grid, ylim([-1 2])

Actually, I want to make it for simulink model. And this way doesn't work!
