empty
pins.
Port Widths
Symbol Width 8 1–1024
Data symbol width in bits. The symbol width should be 8 for
byte-oriented interfaces.
Number of symbols 4 1–1024 Specifies the number of symbols that are transferred per beat.
Width of the channel port 1 1–32 Specifies the width of the
channel
signal.
Width of the error port 1 1–1024 Specifies the width of the
error
signal.
Width of the empty port 1 1–1024 Specifies the width of the
empty
signal.
Timing Attributes
Ready latency 0 0–8
Specifies the delay between the
ready
and
valid
signals. Refer
to the Avalon Interface Specification for more information.
Number of beats per cycle 1 1–1024 Specifies the number of beats per cycle.
Channel Attributes
Max channel number 1 —
Specifies the maximum number of channels that the interface
supports.
API Streaming Interface (Note 1)
Width of API interface data signal 64 — The width of the data signal.
Width of API return interface data
signal
64 — The width of the return interface data signal.
Note to Table 1–2:
(1) This interface is required only for the Avalon-ST Source BFM with Avalon-ST API Wrapper which is used in mixed language simulations.
