-// =head1 SYNOPSIS
-// Bus Functional Model (BFM) for a Avalon Streaming Source
-//-----------------------------------------------------------------------------
-// =head1 DESCRIPTION
-// This is a Bus Functional Model (BFM) for a Avalon Streaming Source.
-// The behavior of each clock cycle of the ST protocol on the interface
-// is governed by a transaction. Transactions are constructed using the
-// the public API methods provided and are then pushed into a dispatch
-// queue, either one at a time or as entire sequences. Response transactions
-// are popped out of a separate response queue and inform the client of
-// statistics such as back pressure latency.

-// This module will dump diagnostic messages to the console during

-// verbosity_pkg. For a given setting, message at that level and all

-// causes all messages to be dumped, while VERBOSITY_FAILURE restricts
-// only failure messages and those tagged as VERBOSITY_NONE to be
-// dumped.
-// The different levels are:
-// =over 4
-// =item 1 VERBOSITY_NONE
-// Messages tagged with this level are always dumped to the console.
-// =item 2 VERBOSITY_FAILURE
-// A fatal simulation error has occurred and the simulator will exit.
-// =item 3 VERBOSITY_ERROR
-// A non-fatal error has occured. An example is a data comparison mismatch.

-// =head1 NAME
-// altera_avalon_st_monitor
-// =head1 SYNOPSIS
-// Bridge with Avalon Bus Protocol Assertion Checker
-//-----------------------------------------------------------------------------
-// =head1 DESCRIPTION
-// This module implements Avalon ST protocol assertion checking for simulation.
-// The component acts as a simple repeater with Avalon bus signals
-// passed through from the sink to source interface.
-// The instantiated altera_avalon_st_monitor snoops all passing Avalon
-// bus signals and performs assertion checking and measures coverage on
-// Avalon Streaming protocol properties.
-// Transactions in transit may also be captured in a transaction buffer and
-// extracted from the monitor via the API.
-// The macro ALTERA_AVALON_SIM_SVA is defined to disable SVA processing
-// The macro ENABLE_ALTERA_AVALON_TRANSACTION_RECORDING must be defined to
-// enable transaction monitoring

-// =head1 SYNOPSIS
-// Bus Functional Model (BFM) for a Avalon Streaming Sink
-//-----------------------------------------------------------------------------
-// =head1 DESCRIPTION
-// This is a Bus Functional Model (BFM) for a Avalon Streaming Sink.
-// The behavior of each clock cycle of the ST protocol on the interface
-// is governed by a transaction. Received bus cycles are captured as
-// transactions and pushed into a response queue. Clients query received
-// transactions by popping them off the queue one by one and extract
-// information using the public API methods provided. Back pressure to
-// a driving source is also applied using the API method set_ready.
