Net "VGA_B[0]", which fans out to "VGA_B[0]", cannot be assigned more than one value

Hi guys. What do you mean by the error? Error (12014): Net "VGA_B[0]", which fans out to "VGA_B[0]", cannot be assigned more than one value Error (12015): Net is fed by "GND"

Error (12015): Net is fed by "VGA_Controller:u1|oVGA_B[0]"

Please help. Thanks.

    I would search your RTL for VGA_B and see if it's being assigned more than once. This typically happens when you have a net assigned by multiple assign statements or if you are coding up a register you have two parallel assignments to the same reg net.
