7.5.11. BFM Log and Message Procedures

These procedures provide support for displaying messages in a common format, suppressing informational messages, and stopping simulation on specific message types.

The following constants define the type of message and their values determine whether a message is displayed or simulation is stopped after a specific message. Each displayed message has a specific prefix, based on the message type in the following table.

You can suppress the display of certain message types. The default values determining whether a message type is displayed are defined in the following table. To change the default message display, modify the display default value with a procedure call to ebfm_log_set_suppressed_msg_mask.

Certain message types also stop simulation after the message is displayed. The following table shows the default value determining whether a message type stops simulation. You can specify whether simulation stops for particular messages with the procedure ebfm_log_set_stop_on_msg_mask.

All of these log message constants type integer.

DEBUG:
EBFM_MSG_INFO

Specifies informational messages, such as configuration register values, starting and ending of tests.

1

Yes

No

INFO:
EBFM_MSG_WARNING

Specifies warning messages, such as tests being skipped due to the specific configuration.

2

Yes

No

WARNING:
EBFM_MSG_ERROR_INFO

Specifies additional information for an error. Use this message to display preliminary information before an error message that stops simulation.

3

Yes

No

ERROR:
EBFM_MSG_ERROR_CONTINUE

Specifies a recoverable error that allows simulation to continue. Use this error for data comparison failures.

4

Yes

No

ERROR:
EBFM_MSG_ERROR_FATAL

Specifies an error that stops simulation because the error leaves the testbench in a state where further simulation is not possible.

N/A

Yes

Cannot suppress

Yes

Cannot suppress

FATAL:
EBFM_MSG_ERROR_FATAL_TB_ERR

Used for BFM test driver or Root Port BFM fatal errors. Specifies an error that stops simulation because the error leaves the testbench in a state where further simulation is not possible. Use this error message for errors that occur due to a problem in the BFM test driver module or the Root Port BFM, that are not caused by the Endpoint Application Layer being tested.
