WebGenerates the Unconstrained Paths report that lists unconstrained setup, hold, recovery, and removal timing paths in the design. An unconstrained path is one that the Timing … WebMay 29, 2013 · Code: assign {cout,sum} = A_reg + B_reg + cin; then register the sum output. Code: always @ (posedge clk) begin sum_reg <= sum; end. Now if you run DC synthesis tool, it should not report any unconstrained path. The reason is that your adder does not have registered input and output.
