Figure 9-60. PFU-based Distributed ROM (Sync_ROM) for LatticeECP/EC and LatticeXP Devices
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 the to enable the output registers in the IPexpress
configuration.
The various ports and their definitions for the memory are included in Table 9-16. The table lists the corresponding
ports for the module generated by IPexpress and for the primitive.
Table 9-16. PFU-based Distributed ROM Port Definitions
Users have the option of enabling the output registers for Distributed ROM (Distributed_ROM). Figures 8-43 and 8-
44 show the internal timing waveforms for the Distributed ROM with these options.
