Lattice Semiconductor
Ports such as Out Clock (OutClock) and Out Clock Enable (OutClockEn) are not available in the hardware primi-
tive. These are generated by IPexpress when the user wants to enable the output registers in the IPexpress config-
uration.
The various ports and their definitions for memory are as per Table 10-16. The table lists the corresponding ports
for the module generated by IPexpress and for the primitive.
Table 10-16. PFU-based Distributed ROM Port Definitions
Users have the option to enable the output registers for Distributed ROM (Distributed_ROM). Figures 10-46 and
10-47 show the internal timing waveforms for the Distributed ROM with these options.
