1. Optional signals.
2. For dual port EBR primitives a trailing ‘A’ or ‘B’ in the signal name specifies the EBR port A or port B respectively.
3. For FIFO RAM mode primitive, a trailing ‘R’ or ‘W’ in the signal name specifies the FIFO read port or write port respec-
4. For FIFO RAM mode primitive FULLI has the same function as CSW(2) and EMPTYI has the same function as CSR(2).
5. In FIFO mode, CLKW is the write port clock, CSW is the write port chip select, CLKR is the read port clock, CSR is the
