- Check that all the interface clocks have been connected and are toggling, and that the core is
not held in reset (that is,
reset_n
is Low).
- Ensure interfaces are enabled (using the AXIS_ENABLE register).
- If
s_axis_din_tready
output is Low ensure that a CTRL
input
and a DIN_WORDS
input have been applied, and that the
interfaces have been enabled over the AXI4-Lite parameter
interface.
- If there is no output from
DOUT
(that is, s_axis_dout_tvalid
is permanently Low) after a full block has been input on CTRL
,
DIN_WORDS
and DIN
, check that an input has
been applied over the DOUT_WORDS
interface.
- Check that the AXI4-Stream waveforms are being followed.
- Check core configuration.
