get_read_data_phase()

This blocking task gets a read data phase previously created by the create_read_transaction()

task.

Note

The get_read_data_phase() sets the RREADY protocol signal at the appropriate time

defined by the data_ready_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 read transaction with start address of 0 and assign

// it to the local read_trans variable.

read_trans = bfm.create_read_transaction(0);

....

// Get the read data phase for the read_trans transaction.

bfm.get_read_data_phase(read_trans, 0); //Note: array element 0.
