Timing parameters
Similarly, all memory, coprocessor, and debug signal expansion signals are defined with
input setup parameters of T
The timing constraints have been adjusted to balance the external timing parameters
with the area of the synthesized core. All inputs are sampled on the rising edge of CLK.
The timing diagrams associated with these timing parameters are shown in Timing
diagrams on page 9-2.
The clock enables are sampled on every rising clock edge:
•
•
All other inputs are sampled on rising edge of CLK when the clock enable is active
HIGH, for example:
•
•
•
Outputs are all sampled on the rising edge of CLK with the appropriate clock enable
active, for example:
•
•
