Detailed Description

Implements an APB bus transaction monitor.

The monitor can snoop transactions for a single slave (i.e. single PSEL) at a time. Observed transactions are passed to subscribers through an analysis port.

The monitor transacrion type, apb_seq_item, is shared with the apb_driver implementation.

Normally the APB monitor is a part of an APB agent.
