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.
