September 2013

execute_read_addr_phase()

This task executes a master read address phase previously created by the

create_read_transaction() function. This phase can be blocking (default) or nonblocking,

defined by the transaction operation_mode field.

It sets the ARVALID protocol signal at the appropriate time, defined by the transaction

address_valid_delay field.

// Declare a local variable to hold the transaction record.

axi_transaction read_trans;

// Create a read transaction with start address of 0 and assign

// it to the local read_trans variable.

read_trans = bfm.create_read_transaction(0);

....

// Execute the read_trans transaction.

bfm.execute_transaction(read_trans);
