ID:18538 Invalid width combination for mixed width dcfifo. The valid width ratio for mixed width dcfifo are 1, 2, 4, 8, 16 and 32 when device family is set to Stratix 10.

CAUSE: You specified width values of the fifo megafunction; however, the width values have an illegal combination. This error usually occurs when you instantiate a megafunction directly in a text file rather than using the IP Parameter Editor.

ACTION: Modify the design and use the width values that have a legal combination. To avoid receiving this message in the future, Intel recommends using the IP Parameter Editor.
