-- Entity: pulse_stamper -- CERN
-- File: pulse_stamper.vhd -- wr-cores/timing
-- Description: a time-tagger which associates a time-tag with an asyncrhonous -- https://www.ohwr.org/project/wr-cores
-- input pulse. --------------------------------------------------------------------------------
-- Author: Javier Serrano (Javier.Serrano@cern.ch) --
-- Date: 24 January 2012 -- unit name : pulse_stamper_sync.vhd
-- Version: 0.01 -- author : Tomasz Wlostowski, based on pulse_stamper by Javier Serrano
-- Todo: Factor out syncrhonizer in a separate reusable block. -- description:
------------------------------------------------------------------------------- --
-- this module allows to time stamp pulses that are synchronous to clk_ref
------------------------------------------------------------------------------- -- domain, so in the domain of the WR time (i.e. tm_tai_i and tm_cycles_i).
-- The generated timestamp is then made available in the clk_sys domain.

-- unit name : fixed_latency_ts_match.vhd
-- author : Tomasz Wlostowski
-- description:
--
-- Module that "fires" (pulse on match_o) when the current TAI time
-- is exactly input timestamped delayed by input latency, i.e.
-- current_TAI_time = ts_tai_i + ts_cycles_i + ts_latency_i
-- The module includes handling of timeout and "missed deadline", i.e. the
-- situation in which current TAI time is already passed the delayed timestamp.
