Building on the skills in behavioral circuit design you established in DP1-2 (and referring back to those Manual sections and Tutorial as needed), in Vivado, create a new module called DFFr containing a behavioral description of a positive (rising) edge triggered D-type FF with an asynchronous active-high reset (rst) input. The module should have inputs: d, clk, rst; and outputs: q, qbar. Hint: An asynchronous reset means one that will force the output to 0 (or possibly some other fixed value, but normally 0) without waiting for a clock edge trigger. In behavioral design, this is straightforward to implement using an if-then test of the reset signal that acts with priority over other, normal (non-reset) circuit functionality. 2. Use the DFFr behavioral skeleton (i.e., incomplete!) code below to implement the DFFr module design. module DFFr( ); input , , ; output reg ; always @ (posedge clk, posedge rst) begin if (expression) begin outputX = ; outputY = ; end else begin outputX = ; outputY = ; end end endmodule
