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.
However, when the output is a double data rate input/output (DDIO)
signal, both edges of the input clock signal (positive and negative) trigger
output transitions
clock and the input clock buffer affect the output DCD.
