signal_max_response_queue_size
signal_min_command_queue_size
signal_fatal_error
Prototype: signal_command_received .
Arguments: None.
Returns: void .
Description: Notifies the testbench that a command has been detected on an Avalon-MM port. The
testbench can respond with a
set_command_wait_time call on receiving this event to
dynamically back pressure the driving Avalon-MM master. Alternatively, the previously
set
wait_time might be used continuously for a set of transactions.
Prototype: signal_error_exceed_max_pending_reads .
Arguments: None.
Returns: void .
Description: Notifies the testbench of the error condition, in which the slave has more than
max_pending_reads pipelined read commands queued and waiting to be processed.
Prototype: signal_max_response_queue_size.
Arguments: None.
Returns: void .
Description: Signals that the maximum pending transaction queue size threshold has been exceeded.
Prototype: signal_min_response_queue_size.
Arguments: None.
Returns: void .
Description: Signals that the pending transaction queue size is below the minimum threshold.
Prototype: signal_fatal_error .
Arguments: None.
Returns: void .
Description: Notifies the testbench that a fatal error has occurred in this module.
