Counter with boolean input

[giu95se]

Hi everyone, I'm trying to make a counter that has a boolean input. I would like the counter to work in the following way: the counter has to stop once I have 5 true samples in a row. How can I do?
I am attaching what I have tried to do in vain.

Hi giu,

two easy options:

1. Use an array with 5 elements. With each call of your counter you shift the array by one element and put the new boolean value in first place. When all 5 elements are TRUE then you got your condition found.
2. Use a shift register to count the TRUE values. With each TRUE you count up by one, with each FALSE you reset to zero. When the counter is >=5 then your condition is met…

WIth each iteration the boolean needs to be true with a certain random probability. Use the dice.

The following is similar to the second suggestion above. For illustration I also added a chart. Make sure to study it in every detail.
