I'm new to verilog so please forgive any ignorance:i'm using the vga_adapter module which for the purpose of this question just requires an x and y value I use two always blocks to do the math and get the values i want: reg [7:0] x0,y0 and reg [7:0] x1,y1 from always block 1 and 2 respectively, how would I code something such that the vga_adapter gets x0,y0 if write_en = 1, or else x1,y1
Hi Bobdoe,Use If else statement like bellow . if (write_en) begin temp1<= x0; temp2<= y0; end else begin temp1<= x1; temp2<= y1; end Best Regards Vikas Jathar Intel Customer Support – Engineering (Under Contract to Intel
Would i put this in a third always block, because from my understanding thats the only way if statements will work? if so, won't I get : Error (10028): Can't resolve multiple constant drivers, due to x1, x0, y1, y0 being in two different always blocks.Thanks for you help.
