2.4.2.5.1. Timing Components

The GPIO IP core timing components consist of three paths.
  • I/O interface paths—from the FPGA to external receiving devices and from external transmitting devices to the FPGA.
  • Core interface paths of data and clock—from the I/O to the core and from the core to I/O.
  • Transfer paths—from half-rate to full-rate DDIO, and from full-rate to half-rate DDIO.
Note: The Timing Analyzer treats the path inside the DDIO_IN and DDIO_OUT blocks as black boxes.
