In a path from an input port to a sequential cell, the data:

  • Is launched outside the device by a clock on the board.
  • Reaches the device port after a delay called the input delay [Synopsys Design Constraints (SDC) definition].
  • Propagates through the device internal logic before reaching a sequential cell clocked by the destination clock.
