execute_read_data_phase()
This task executes a read data phase (beat) previously created by the create_slave_transaction()
task. This phase can be blocking (default) or nonblocking, as defined by the transaction record
operation_mode field.
The execute_read_data_phase() task sets the RVALID protocol signal at the appropriate time
defined by the transaction record data_valid_delay field and sets the transaction_done field to 1
to indicate the whole read transaction has completed.
Example
// Declare a local variable to hold the transaction record.
axi4_transaction read_trans;
// Create a slave transaction and assign it to the local
// read_trans variable.
read_trans = bfm.create_read_transaction(0);
....
// Execute the read data phase for the read_trans transaction.
bfm.execute_read_data_phase(read_trans, 0); //Note: array element 0
