LogiCORE FIFO Generator v2.1 - How do you disable FWFT for an independent clock FIFO?

Description

General Description: 

How do you disable FWFT for an independent clock FIFO?

Solution

When using the independent clock FIFO, FWFT is supported and must be enabled by selecting Registered Outputs with Read Latency 0, as indicated on page 5 of the datasheet (note 2). 

 

FWFT can be enabled only if Registered Outputs AND Read Latency is 0. If the Read Latency is not 0, FWFT should not be placed in FIFO indepedent clock mode.
