Due to a problem in the Intel® Quartus® Prime Pro Edition software version 20.4 and earlier, you may see the EMIF Traffic Generator 2.0 (TG2) incorrectly assert the fail signal when the TG2 is configured such that TG_USER_WORM_EN = 1, TG_RETURN_TO_START_ADDR = 1, TG_ADDR_MODE = random or random-sequential, and TG_WRITE/READ_REPEAT_COUNT > 1.
This problem occurs because the random address generator does not wait for the read/write repeats to finish on the last iteration of the loop before resetting the address, which causes an incorrect comparison in TG2.
This problem is fixed starting with the Intel® Quartus® Prime Pro Edition software version 21.1.
