ebfm_log_set_stop_on_msg_mask Verilog HDL Function
The ebfm_log_set_stop_on_msg_mask procedure controls which message types stop
simulation. This procedure alters the default behavior of the simulation when errors
occur as described in the
Table 17–36 on page 17–38 .
ebfm_log_open Verilog HDL Function
The ebfm_log_open procedure opens a log file of the specified name. All displayed
messages are called by ebfm_display and are written to this log file as simulator
standard output.
ebfm_log_close Verilog HDL Function
The ebfm_log_close procedure closes the log file opened by a previous call to
ebfm_log_open .
Verilog HDL Formatting Functions
The following procedures and functions are available in the
altpcietb_bfm_driver_rp.v
. This section outlines formatting functions that are only
used by Verilog HDL. All these functions take one argument of a specified length and
return a vector of a specified length.
Table 17–40. ebfm_log_set_stop_on_msg_mask
Location altpcietb_bfm_driver_rp.v
Syntax ebfm_log_set_stop_on_msg_mask (msg_mask)
Argument msg_mask
This argument is
reg [EBFM_MSG_ERROR_CONTINUE:EBFM_MSG_DEBUG] .
A 1 in a specific bit position of the msg_mask causes messages of the type corresponding to
the bit position to stop the simulation after the message is displayed.
Table 17–41. ebfm_log_open
Location altpcietb_bfm_driver_rp.v
Syntax ebfm_log_open (fn)
Argument fn This argument is type string and provides the file name of log file to be opened.
Table 17–42. ebfm_log_close Procedure
Location altpcietb_bfm_driver_rp.v
Syntax ebfm_log_close
Argument NONE
