The m_axis_video tready signal can be asserted
before, during or after the cycle in which the TPG core asserted m_axis_video_tvalid.
The assertion of m_axis_video_tready might be
dependent on the value of m_axis_video_tvalid.
A slave that can immediately accept data qualified by m_axis_video_tvalid, should pre-assert its m_axis_video_tready signal until data is received.
Alternatively, m_axis_video_tready can
be registered and driven the cycle following VALID
assertion.
Recommended: To minimize latency, your custom
core's slave interface should drive READY independently, or preassert READY.
