DCD Measurement Techniques
DCD is measured at an FPGA output pin driven by registers inside the
corresponding I/O element (IOE) block. When the output is a single data
rate signal (non-DDIO), only one edge of the register input clock (positive
or negative) triggers output transitions
present on the input clock signal or caused by the clock input buffer or
different input I/O standard does not transfer to the output signal.
