changing output from two always blocks

[Altera_Forum]

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.

The error you mention is from having two always blocks, as it says. Maybe post your code here. That will make it easier to answer your question.
