// Fifo implementation defines:
// If FPGA and XILINX are defined, Xilinx's BlockSelectRAM+ is instantiated for Fifo storage.
// 16 bit width is used, so 8 bits of address ( 256 ) locations are available. If RAM_DONT_SHARE is not defined (commented out),
// then one block RAM is shared between two FIFOs. That means each Fifo can have a maximum address length of 7 - depth of 128 and only 6 block rams are used
// If RAM_DONT_SHARE is defined ( not commented out ), then 12 block RAMs are used and each Fifo can have a maximum address length of 8 ( 256 locations )
// If FPGA is not defined, then ASIC RAMs are used. Currently there is only one version of ARTISAN RAM supported. User should generate synchronous RAM with
// width of 40 and instantiate it in pci_tpram.v. If RAM_DONT_SHARE is defined, then these can be dual port rams ( write port
// in one clock domain, read in other ), otherwise it must be two port RAM ( read and write ports in both clock domains ).
// If RAM_DONT_SHARE is defined, then all RAM address lengths must be specified accordingly, otherwise there are two relevant lengths - PCI_FIFO_RAM_ADDR_LENGTH and
// WB_FIFO_RAM_ADDR_LENGTH.
