Parenthesis error on my assign command for my output (dataflow level)

assign    F=((A&B)(~|)(C|D))^((C|D)(~&)((~)A(~|)C));

I have no idea why I get this error:

Error: (vlog-13069) C:/Users/JsnK/Desktop/New folder/circuit1_dataflowlvl.v(6): near "(": syntax error, unexpected '('.

Here is a schematic : http://prntscr.com/ld9n7a

Solution

  • Move the inversions outside of the parentheses:

    assign F = ~((A&B) | (C|D)) ^ ~((C|D) & ~( ~A | C));
