I$\text{'}$m trying to create a random delay but for some reason it only works every other time.

My code:

always @$($posedge clk or posedge reset$)$ begin

if $($reset$)$ begin

delay$\_$counter $<=0$;

random$\_$calculated $<=0$;

end else if $($state $==$ WAIT$\_$DELAY$)$ begin

if $(!$random$\_$calculated$)$ begin

delay$\_$counter $<=(($random$\_$seed $\%($DELAY$\_$MAX $-$ DELAY$\_$MIN $+1))+$ DELAY$\_$MIN$)*$ CLK$\_$FREQ;

random$\_$calculated $<=1$;

end else if $($delay$\_$counter $>0)$ begin

delay$\_$counter $<=$ delay$\_$counter $-1$;

end

end else begin

random$\_$calculated $<=0$; $//$ Reset flag in other states

end

end

$//$ Pseudo$-$random number generator $($LFSR$)$

always @$($posedge clk or posedge reset$)$ begin

if $($reset$)$

random$\_$seed $<=16$'hACE$1$;

else if $($state $==$ IDLE$)$

random$\_$seed $<=$ random$\_$seed $^$ timer; $//$ Add variability

else

random$\_$seed $<=\{$random$\_$seed$[14$:$0],$ random$\_$seed$[15]^$ random$\_$seed$[13]\}$;

end
