Why is the fail flag in the EMIF Traffic Generator 2.0 not asserted when the WORM mode is enabled, and a data mismatch is encountered?

Description

When the TG_LOOP_COUNT register is greater than 1 and the Write Once Read Many (WORM) mode is enabled, the Traffic Generator Fail (TGF) flag is not asserted when a data mismatch is encountered due to a problem in the Intel® Quartus® Prime Pro Edition software version 20.4.

Note that the WORM mode is disabled by default.

Resolution

The problem has been fixed in the Intel® Quartus® Prime Pro Edition software version 21.1 .
