Chapter 5: Avalon-ST Monitor 5–3
Application Program Interface
May 2011 Altera Corporation Avalon Verification IP Suite User Guide
Application Program Interface
This section describes the API for the Avalon-ST Monitor.
Assertion Checking
Assertion checking methods enable and disable protocol assertions that are used to
ensure protocol compliance. For example, the
enable_a_no_data_outside_packet
method enables the assertion that verifies that no data is transmitted between the
assertion of the
endofpacket
and the next
startofpacket
signals. If a violation is
found, an error message is displayed on the console running the simulation. Error
flags also are displayed in the waveform viewer. By default all assertions are enabled.
However, depending on the parameterization of a the Avalon-ST interface, some
assertions are automatically disabled. For example, you might have to disable some
assertion checking to avoid generating error messages when injecting protocol errors
to test the Avalon-ST component’s error handling capability. The names of all
methods that implement assertions begin with
set_enable_a
. By default, if your
testbench includes the Avalon-ST monitor, the checking function is enabled. You can
disable checking with the
DISABLE_ALTERA_AVALON_SIM_SVA
macro.
set_enable_a_empty_legal()
set_enable_a_less_than_max_channel()
set_enable_a_no_data_outside_packet()
Prototype:
set_enable_a_empty_legal().
Arguments:
Boolean
.
Returns:
Void
.
Description: Enables an assertion that ensures
empty
is 0 except when
endofpacket
is
asserted and that
empty
is always less than the number of symbols in a
packet.
Prototype:
set_enable_a_less_than_max_channel().
Arguments:
Boolean
.
Returns:
Void
.
Description: Enables an assertion that ensures that the value of the
channel
signal is
less than the maximum number of channels.
Prototype:
set_enable_a_no_data_outside_packet().
Arguments:
Boolean
.
Returns:
Void
.
Description: Enables an assertion that ensures
valid
data is not transferred outside of
a packet when the interface uses packet transmission.
