8.3.3.1.2 D Flip-Flop/Latch

When used to implement a sequential logic element, the two input signals from the connection mux go to the data (D) and clock (CLK) inputs of the flip-flop or latch, with the output going back to the connection mux. This macro-cell has initial state parameters as well as clock and output polarity parameters that can be configured.

The operation of the D flip-flop/latch follows the functional descriptions below:

  • The clock polarity is configurable and can be set to non-inverted (CLK) or inverted (nCLK).
    • DFF with CLK: CLK is rising edge triggered, then Q = D; otherwise Q does not change.
    • DFF with nCLK: CLK is falling edge triggered, then Q = D; otherwise Q does not change.
    • Latch with CLK: when CLK is Low, then Q = D; otherwise Q remains the previous value (input D has no effect on the output, when CLK is High).
    • Latch with nCLK: when CLK is High, then Q = D; otherwise Q remains the previous value (input D has no effect on the output, when CLK is Low).
  • The output polarity is configurable and can be set to non-inverted (Q) or inverted (nQ).

Table 8-19 and Table 8-20 show the truth tables for the D flip-flop and D latch, respectively.
