Description
BFM procedures
init_axilite_if_signals
- This function returns an AXILITE interface with initialized signals.
- All AXILITE input signals are initialized to 0
- All AXILITE output signals are initialized to Z
- awprot and arprot are initialized to UNPRIVILEGED_NONSECURE_DATA

Description
axilite_write
This procedure writes data to the AXILITE interface specified in axilite_if
- The protection setting is set to UNPRIVILEGED_NONSECURE_DATA in this procedure
- The byte enable input is set to 1 for all bytes in this procedure
- When the write is completed, a log message is issued with log ID id_for_bfm

Description
axilite_write
This procedure writes data to the AXILITE interface specified in axilite_if
- When the write is completed, a log message is issued with log ID id_for_bfm

Description
axilite_read
This procedure reads data from the AXILITE interface specified in axilite_if,
and returns the read data in data_value.

Description
axilite_check
This procedure reads data from the AXILITE interface specified in axilite_if,
and compares it to the data in data_exp.
- If the received data inconsistent with data_exp, an alert with severity
alert_level is issued. - If the received data was correct, a log message with ID id_for_bfm is issued.
