rectangular-image transaction with two lines, +# then a malformed header followed by a clean retry. +# - Checks: The FSM must emit the packed rectangular-image header in the same +# field order the RTL exports from the spec-defined repeated-byte header, +# forward the exact programmed number of data words, assert frame `TLAST` +# only on the final line, and recover cleanly after a malformed header word. +# - Timing: The source holds each beat until `sAxisTReady` rises so the checks +# reflect the FSM's actual per-beat acceptance rather than idealized traffic. + +import os + +import

bug-prone surface is its packet-state logic rather than a set +# of static parameters. +# - Stimulus: Drive raw CoaXPress stream, control-ack, event, and heartbeat +# words using spec-shaped packet prefixes and trailers where the current RTL +# can consume them, plus malformed-field and link-drop sequences. +# - Checks: The lane must emit the right config/data/heartbeat payloads, pulse +# `ioAck` and `eventAck` at the correct points, preserve payload `TUSER` +# bits, and reset cleanly after malformed packets or `rxLinkUp` loss. +# - Timing: The bench samples every output pulse cycle-by-cycle because the DUT +# exposes only master-side pulse semantics with no backpressure input. + +import cocotb + +from tests.common.regression_utils import run_surf_vhdl_test +from
