--- /dev/null
+SimpleLTInitiator1/SimpleLTTarget1
+----------------------------------
+
+- LT Initiator/Target model using the base (standard) tlm socket
+- Added support for DMI in SimpleLTTarget1
+
+SimpleLTInitiator1_DMI
+----------------------
+
+- uses DMI transactions, the DMI structure is using the DMI-hint
+ to check if a DMI request would make sense.
+- uses a single transport_dbg transaction at end_of_simulation()
+
+SimpleLTInitiator2/SimpleLTTarget2
+----------------------------------
+
+- LT Initiator/Target model using the convenience tlm socket
+- Target and Initiator model use the REGISTER_DEBUGTRANSPORT macro to register
+ a transport callback to the socket
+- Added support for DMI handling, callback registration with
+ REGISTER_DMI
+- SimpleLTTarget2 does not register the transport_dbg callback, so that
+ we are able to test this case in bus_dmi.
+
+SimpleLTInitiator2_DMI
+----------------------
+
+- uses DMI transactions, but ignoring the DMI hint
+- uses a single transport_dbg transaction at end_of_simulation()
+
+SimpleLTInitiator3
+------------------
+
+- LT Initiator model using the convenience tlm socket
+- Initiator model uses the endEvent of the socket to wait until the
+ transaction is finished
+
+SimpleLTInitiator3_DMI
+----------------------
+
+- based on SimpleInitiator3, uses DMI (without DMI hint)
+
+SimpleATInitiator1/SimpleATTarget1
+----------------------------------
+
+- AT Initiator/Target model implementing the AT protocol
+- one call of nb_transport for each timing point in the protocol (BEGIN_REQ,
+ END_REQ, BEGIN_RESP and END_RESP)
+
+SimpleATInitiator2/SimpleATTarget2
+----------------------------------
+
+- AT Initiator/Target model implementing the AT protocol with timing annotation
+- only a call of nb_transport for the start of a phase (BEGIN_REQ and
+ BEGIN_RESP)
+- end of a phase is notified via timing annotation (t argument)
+
+CoreDecouplingLTInitiator
+-------------------------
+
+- LT Initiator using 'Core Decoupling'
+
+ExplicitLTTarget
+----------------
+
+- LT Target that uses explicit timing (calls wait)
+- added support for debug transactions
+
+ExplicitLTTarget
+----------------
+
+- AT Target, only registers nb_transport
+
+SimpleBus
+---------
+
+- Simple bus model
+- Runtime switcheable between LT and AT (can only switch if no transactions
+ are pending)
+- No limitation on number of pending transactions (all targets that can return
+ false must support multiple transactions)
+- added support for DMI and debug transactions
+- LT mode:
+-- Forward nb_transport calls to initiator/targets
+-- Only one active request/response phase
+- AT mode:
+-- Incoming transactions are queued
+-- AT protocol is executed from a different SC_THREAD
+-- A target is notified immediately of the end of a transaction (using timing
+ annotation). This is needed because the initiator can re-use the
+ transaction (and the target may use the transaction pointer to identify the
+ transaction)
