function void
svt_xactor::inform_notify_cb_exec

( string name , svt_notify notify )

Callback issued for every svt_notify which supports callback based notification tracking.

This method issues the inform_notify callback.

Overriding implementations in extended classes must call the super version of this method.

name - Name identifying the svt_notify if provided, or identifying the transactor if the inform_notify is being issued for the 'notify' field on the transactor.

notify - The svt_notify instance that is being provided for use. This field is set to null if the inform_notify is being issued for the 'notify' field on the transactor.

function bit
svt_xactor::is_cov_complete

( int kind , ref string report )

Check on the coverage status as recognized by the coverage callbacks.

kind - The kind of report being requested. -1 reserved for 'generic' report.

report - Short textual report describing coverage status.

protected function bit
svt_xactor::is_valid_cfg_type

( svt_configuration cfg )

Expected to return a 1 if the supplied configuration object is of the correct type for the transactor. Extended classes implementing specific transactors will provide an extended version of this method and call it directly.

protected function bit
svt_xactor::is_valid_chan

( int chan_id )

Returns a 1 if the specified channel ID is within the range used by the transactor.

protected function bit
svt_xactor::is_valid_xact_type

( int chan_id , svt_sequence_item_base xact )

Returns a 1 if the supplied transaction object is of the correct type for the channel with the specified ID.

protected task
svt_xactor::main

( )

VMM main method.

Superseding tasks
	svt_broadcast :: main

protected function void
svt_xactor::monitor_chan

( svt_channel chan , string xact_type , string chan_name , bit display_as_note = 0 )

Monitors the provided channel, reporting all PUT and GOT activity.

chan - Channel that is to be monitored.

xact_type - String representing the channel transaction type.

chan_name - String indicating the channel name.

display_as_note - Bit indicating whether reporting should occur as a NOTE (display_as_note = 1) or VERBOSE (display_as_note = 0) vmm message.

protected function void
svt_xactor::monitor_chan_activity

( svt_channel chan , string xact_type , string chan_name , svt_channel :: notifications_e chan_activity , bit display_as_note = 0 )

Monitors the provided channel, reporting all channel activity of the type indicated by chan_activity.

chan - Channel that is to be monitored.

xact_type - String representing the channel transaction type.

chan_name - String indicating the channel name.

chan_activity - vmm_channel enum value indicating which channel activity is to be tracked. Currently only supports monitoring of PUT and GOT activity.

display_as_note - Bit indicating whether reporting should occur as a NOTE (display_as_note = 1) or VERBOSE (display_as_note = 0) vmm message.

virtual function void
svt_xactor::monitor_xactor_chan

( int chan_id , bit display_as_note = 0 )

Monitors the indicated transactor channel, reporting all PUT and GOT activity.

chan_id - Channel identifier within the range used by the transactor.

display_as_note - Bit indicating whether reporting should occur as a NOTE (display_as_note = 1) or VERBOSE (display_as_note = 0) vmm message.

function void
svt_xactor::new

( string suite_name , string name = "svt_xactor_inst", uvm_component parent = null )

CONSTRUCTOR: Creates a new instance of the svt_xactor class.

suite_name - Identifies the product suite to which the xactor object belongs.

name - Instance name of this object.

parent - Parent for this object.

function void
svt_xactor::pre_abort

( )

UVM pre_abort callback

Superseded functions
	uvm_component :: pre_abort

function void
svt_xactor::reconfigure

( svt_configuration cfg )

Updates the transactors configuration with data from the supplied object. This method always results in a call to change_dynamic_cfg. If the transactor has not been started calling this method also results in a call to change_static_cfg.

function void
svt_xactor::recycle_timer

( ref svt_timer timer )

Method to add this timer to recycled_timer, which is a queue of recycled timers. Timers should only be recycled if the client is sure that the timer is no longer in use, and only if the timer was created via a call to get_recycled_timer.

timer - The timer to be recycled. Passed as a ref so it can be set to null before return.

function void
svt_xactor::set_instance

( string inst )

Sets the instance name associated with this transactor.

inst - The new instance name to be associated with this subenv.

protected function void
svt_xactor::start_cb_exec

( )

Called by main to allow callbacks to initiate activities. This callback is issued during main so that any processes initiated by this callback will be torn down if reset_xactor() is called.

This method issues the start callback.

Overriding implementations in extended classes must call the super version of this method.

protected function void
svt_xactor::stop_cb_exec

( )

Called to allow callbacks to suspend activities.

This method issues the stop callback.

Overriding implementations in extended classes must call the super version of this method.

svt_err_check attribute
svt_xactor::err_check = null

Local svt_err_check instance that may be specific to the transactor, or otherwise shared across a subeystem (e.g., subenv).

svt_event_pool attribute
