Loop index overflow problem

Hi there, I've wrote a little VHDL program in Quartus II. I'd like to separate one big std_logic_vector into small fix-length std_logic_vectors and the compile told me that the index is out...

thats because j stops at 504, and you print j+7

I dont see a p_count + 7 offset anywhere in your VHDL.

You'll find that j actually finishes the loop on 512.

i wrote this,

p := datain(p_count+i_width-1 downto p_count); --i_width=8, so this is my "p_count+7"

p_count:=p_count+i_width;
