Hi,
I need some advices for my RTL design.
Is there any differences about timing performance between these two coding style below?
Does the second coding style have a better timing performance?
1)
wire [511:0] A, B, C;
assign C = A&B;
2)
wire [511:0] A, B, C;
wire [255:0] C1;
assign C1 = A[255:0] & B[255:0];
wire [255:0] C2;
assign C2 = A[511:256] & B[511:256];
assign C = {C2,C1};
Thanks
Son
