apb_monitor

class apb_monitor extends uvm_component

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.

Summary

apb_monitor	Implements an APB bus transaction monitor.
Variables
apb_if	Reference to the APB bus interface
apb_index	Identifies which PSEL line is this monitor connected to.
ap	Analysis port through which to broadcast observed APB transactions.
Functions
new	Conventional UVM component constructor.
build_phase	Instantiates the analysis port.
run_phase	Forks off a forever loop that monitors APB transactions for slave selected by ::apb_index.
report_phase	Presently a stub function.

Variables

apb_if

virtual apb_if APB

Reference to the APB bus interface

apb_index

int apb_index

Identifies which PSEL line is this monitor connected to.

ap

uvm_analysis_port #( apb_seq_item ) ap

Analysis port through which to broadcast observed APB transactions.

Functions

new

extern function new( string name = "apb_monitor",
uvm_component parent = null )

Conventional UVM component constructor.

build_phase

extern function void build_phase( uvm_phase phase )

Instantiates the analysis port.

run_phase

extern task run_phase( uvm_phase phase )

Forks off a forever loop that monitors APB transactions for slave selected by ::apb_index.

report_phase

extern function void report_phase( uvm_phase phase )

Presently a stub function.
