3.3. Parameters

Table 9.  Configurable Parameters
Parameter Legal Values Description
Bits per symbol 1–32 These parameters determine the width of the FIFO.

FIFO width = Bits per symbol * Symbols per beat, where:
Bits per symbol is the number of bits in a symbol, and
Symbols per beat is the number of symbols transferred in a beat.

Symbols per beat 1–32
Error width 0–32 The width of the error signal.
FIFO depth 1–32 The FIFO depth. An output pipeline stage is added to the FIFO to increase performance, which increases the FIFO depth by one.
Use packets Turn on this parameter to enable packet support on the Avalon® -ST data interfaces.
Channel width 1–32 The width of the channel signal.
Avalon® -ST Single Clock FIFO Only
Use fill level Turn on this parameter to include the Avalon® -MM control and status register interface.
Avalon® -ST Dual Clock FIFO Only
Use sink fill level Turn on this parameter to include the Avalon® -MM control and status register interface in the input clock domain.
Use source fill level Turn on this parameter to include the Avalon® -MM control and status register interface in the output clock domain.
Write pointer synchronizer length 2–8 The length of the write pointer synchronizer chain. Setting this parameter to a higher value leads to better metastability while increasing the latency of the core.
Read pointer synchronizer length 2–8 The length of the read pointer synchronizer chain. Setting this parameter to a higher value leads to better metastability.
Use Max Channel Turn on this parameter to specify the maximum channel number.
Max Channel 1–255 Maximum channel number.
