Websequential circuit, our DFT method augments the sequential circuit with thru functions so that the sequential circuit becomes acyclically testable. The rest of the paper is organized as follows. In Section II, we define R-graph as a representation of sequential circuits and introduce a new concept of testability called acyclic testability ... WebCombinational vs. Sequential Logic Combinational logic no feedback among inputs and outputs outputs are a pure function of the inputs e.g., seat belt light: ... Basic D Flip Flop // Basic D flip-flop module basic_D_FF (q, d, clk); output q; input d, clk; reg q; // Indicate that q is stateholding
