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.

ebfm_display Verilog HDL Function
The
ebfm_display
procedure or function displays a message of the specified type to the simulation
standard output and also the log file if
ebfm_log_open
is called.
A message can be suppressed, simulation can be stopped or both based on the default settings of the
message type and the value of the bit mask when each of the procedures listed below is called. You can call
one or both of these procedures based on what messages you want displayed and whether or not you want
simulation to stop for specific messages.
• When
eb fm_log_set_suppressed_msg_mask
is called, the display of the message might be
suppressed based on the value of the bit mask.
• When
ebfm_log_set_stop_on_msg_mask
is called, the simulation can be stopped after the message is
displayed, based on the value of the bit mask.

Syntax
Verilog HDL: dummy_return:=ebfm_display(msg_type, message);
Argument
msg_type Message type for the message. Should be one of the constants
defined in Table 18–36 on page 18–41.
message The message string is limited to a maximum of 100 characters.
Also, because Verilog HDL does not allow variable length
strings, this routine strips off leading characters of 8’h00 before
displaying the message.
Return always 0 Applies only to the Verilog HDL routine.
