get_read_addr()

This nonblocking function returns the actual address addr of a particular index in a read

transaction. It is used in a monitor test program as a helper function to return the address of a

byte of data in the monitor memory. If the corresponding index does not exist, then this function

returns false; otherwise, it returns true.
