WebDraw a representative circuit of the synthesized hardware based on the following procedural blocks. Draw all circuits using only 1-bit clocked flip-flops and 2-input primitive logic gates. Assume a,b,c are 1-bit reg. Circuit 1: always @ (posedge clk ) begin b = a; c = b; end Circuit 2: always @ (posedge clk ) begin b <= a; c <= b; end Circuit 3: WebAfter the wire keyword, you must either give an identifier (the name of a wire), or a [ (in case of a multi-bit wire), or specify whether the wire is signed or unsigned (default). Instead you have used a reserved keyword reg. You can't have a signal that is both a wire and a reg.
