FIFO Shift Register

[downerdce]

I think this should be a pretty easy question...

I want to have a random number populate into an array using shift registers. The thing is, I want the array to be a fixed size and then for the value to go into the top, shift everything down and drop the bottom value. I can't seem to figure out how to fix the size of the array.

code attached, help appreciated!

I figured it out...

just use array subset to grab the n number of values from the top you want and push them out to shift register.
