Dual ports means each port can do either write OR read on each port in clock cycle, not both.

--- Quote End ---

I added another process,

ShowResults:Process(Clock,show)

variable i:integer range 0 to 7:=0;

begin

IF rising_edge(clock) and show='1' THEN

D<=ram1(2*i);

S<=ram1(2*i+1);

i:=i+1;

end if;

end process;

acmain<='0' when Z=16 else '1'; --Z is a counter to read 16 elements and then stop activating the first process.acmain is in sensitivity list of first process I listed in first post.

show<='1' when acmain='0' else '0';

So, I activate it when I deactivate the first process , So I can either read or write. However Still unable to infer to memory. What is the best solution for that
