Transaction Monitoring
Transaction monitoring is carried out through the transaction collector module. The
transaction collector collects the transactions, encapsulates them into descriptors, and
inserts the transactions into queue. The API provides the mechanism to query the
transactions in queue and disposes them as they are processed. By default, the
transaction collector module is disabled. You must define the
ENABLE_ALTERA_AVALON_TRANSACTION_RECORDING Verilog macro to enable this feature.
This macro is required to ensure backward compatibility and to avoid breaking
existing test cases.
get_transaction_channel()
Prototype: set_enable_c_transfer().
Arguments: Boolean .
Returns: Void .
Description: Enables a coverage point that ensures test coverage of a valid signal is
asserted correctly for different channels. It is disabled when the ready or
valid signals are not supported.
Prototype: set_enable_c_transaction_after_reset().
Arguments: Boolean .
Returns: Void .
Description: Enables a coverage point that ensures test coverage for transaction on the
first cycle after reset.
Prototype: set_enable_c_valid_non_ready().
Arguments: Boolean .
Returns: Void .
Description: Enables a coverage point that ensures test coverage for valid signal when
ready is deasserted. It is disabled when the readyLatency is greater than
0.
Prototype: get_transaction_channel() .
Arguments: None.
Returns: STChannel_t .
Description: Returns the channel identifier for the most recently removed transaction.
