Detailed Description

template<typename TYPES = chi::chi_protocol_types>
class chi::scv::chi_trx_recorder< TYPES >

The TLM2 transaction recorder.

This module records all TLM transaction to a SCV transaction stream for further viewing and analysis. The handle of the created transaction is storee in an tlm_extension so that another instance of the chi_recorder e.g. further down the path can link to it.

Constructor & Destructor Documentation

◆ chi_trx_recorder()

template<typename TYPES = chi::chi_protocol_types>

chi::scv::chi_trx_recorder< TYPES >::chi_trx_recorder	(	const char *	name,
		bool	recording_enabled = `true`,
		SCVNS scv_tr_db *	tr_db = `SCVNS scv_tr_db::get_default_db()`
	)

inline

The constructor of the component.

Parameters

name	is the SystemC module name of the recorder
tr_db	is a pointer to a transaction recording database. If none is provided the default one is retrieved. If this database is not initialized (e.g. by not calling scv_tr_db::set_default_db() ) recording is disabled.

Definition at line 125 of file chi_recorder.h.

Member Function Documentation

◆ b_snoop()

template<typename TYPES >

void chi::scv::chi_trx_recorder< TYPES >::b_snoop	(	typename TYPES::tlm_payload_type &	trans,
		sc_core::sc_time &	delay
	)

override

The blocking snoop function.

This type of transaction is forwarded and recorded to a transaction stream named "b_tx" with current timestamps. Additionally a "b_tx_timed" is been created recording the transactions at their annotated delay

Parameters

trans	is the generic payload of the transaction
delay	is the annotated delay

Definition at line 410 of file chi_recorder.h.

◆ b_transport()

template<typename TYPES >

void chi::scv::chi_trx_recorder< TYPES >::b_transport	(	typename TYPES::tlm_payload_type &	trans,
		sc_core::sc_time &	delay
	)

override

The blocking transport function.

This type of transaction is forwarded and recorded to a transaction stream named "b_tx" with current timestamps. Additionally a "b_tx_timed" is been created recording the transactions at their annotated delay

Parameters

trans	is the generic payload of the transaction
delay	is the annotated delay

Definition at line 354 of file chi_recorder.h.

◆ get_direct_mem_ptr()

template<typename TYPES >

bool chi::scv::chi_trx_recorder< TYPES >::get_direct_mem_ptr	(	typename TYPES::tlm_payload_type &	trans,
		tlm::tlm_dmi &	dmi_data
	)

override

The direct memory interface forward function.

This type of transaction is just forwarded and not recorded.

Parameters

trans	is the generic payload of the transaction
dmi_data	is the structure holding the dmi information

Returns: if the dmi structure is valid

Definition at line 763 of file chi_recorder.h.

◆ invalidate_direct_mem_ptr()

template<typename TYPES >

void chi::scv::chi_trx_recorder< TYPES >::invalidate_direct_mem_ptr	(	sc_dt::uint64	start_addr,
		sc_dt::uint64	end_addr
	)

override

The direct memory interface backward function.

This type of transaction is just forwarded and not recorded.

Parameters

start_addr	is the start address of the memory area being invalid
end_addr	is the end address of the memory area being invalid

Definition at line 782 of file chi_recorder.h.

◆ isRecordingBlockingTxEnabled()

template<typename TYPES = chi::chi_protocol_types>

bool chi::scv::chi_trx_recorder< TYPES >::isRecordingBlockingTxEnabled ( ) const

inline

get the current state of transaction recording

Returns: if true transaction recording is enabled otherwise transaction recording is bypassed

Definition at line 232 of file chi_recorder.h.

◆ isRecordingNonBlockingTxEnabled()

template<typename TYPES = chi::chi_protocol_types>

bool chi::scv::chi_trx_recorder< TYPES >::isRecordingNonBlockingTxEnabled ( ) const

inline

get the current state of transaction recording

Returns: if true transaction recording is enabled otherwise transaction recording is bypassed

Definition at line 238 of file chi_recorder.h.

◆ nb_transport_bw()

template<typename TYPES >

tlm::tlm_sync_enum chi::scv::chi_trx_recorder< TYPES >::nb_transport_bw	(	typename TYPES::tlm_payload_type &	trans,
		typename TYPES::tlm_phase_type &	phase,
		sc_core::sc_time &	delay
	)

override

The non-blocking backward transport function.

This type of transaction is forwarded and recorded to a transaction stream named "nb_bw" with current timestamps.

Parameters

trans	is the generic payload of the transaction
phase	is the current phase of the transaction
delay	is the annotated delay

Returns: the sync state of the transaction

Definition at line 579 of file chi_recorder.h.

◆ nb_transport_fw()

template<typename TYPES >

tlm::tlm_sync_enum chi::scv::chi_trx_recorder< TYPES >::nb_transport_fw	(	typename TYPES::tlm_payload_type &	trans,
		typename TYPES::tlm_phase_type &	phase,
		sc_core::sc_time &	delay
	)

override

The non-blocking forward transport function.

This type of transaction is forwarded and recorded to a transaction stream named "nb_fw" with current timestamps.

Parameters

trans	is the generic payload of the transaction
phase	is the current phase of the transaction
delay	is the annotated delay

Returns: the sync state of the transaction

Definition at line 491 of file chi_recorder.h.

◆ transport_dbg()

template<typename TYPES >

unsigned int chi::scv::chi_trx_recorder< TYPES >::transport_dbg ( typename TYPES::tlm_payload_type & trans )

override

The debug transportfunction.

The debug transport function.

This type of transaction is just forwarded and not recorded.

Parameters

trans is the generic payload of the transaction

Returns: the sync state of the transaction
