The timing parameters for the dual-redundant core compare logic input control buses,
DCCMINP[7:0] and DCCMINP2[7:0], are implementation-defined. Contact the implementer
of the macrocell you are working with.
15.2.2 Output ports timing parameters
Most output ports have a maximum output delay of 60%, that is the SoC is enabled to use 60%
of the clock cycle.
Table 15-10 shows the timing parameter for the miscellaneous output port.
Table 15-11 shows the timing parameters for the interrupt output ports.
Table 15-12 shows the timing parameters for the AXI master output port.
