First In First Out (FIFO, FIFO_DC) - EBR Based
The EBR blocks in MachXO devices can be configured as Dual Clock First In First Out Memories, FIFO_DC. IPex-
press allows users to generate the Verilog-HDL or VHDL along EDIF netlist for the memory size, according to
design requirements.
IPexpress generates the FIFO_DC memory module as shown in Figure 9-28.
Figure 9-28. FIFO Module Generated by IPexpress
The generated module makes use of these EBR blocks or primitives. For the memory sizes smaller than an EBR
block, the module will be created in one EBR block. If the specified memory is larger than one EBR block, multiple
EBR blocks can be cascaded, in depth or width (as required to create these sizes).
