Known Issues

-(Xilinx Answer 45744) ISE 13.4 Coregen FIFO Generator v8.4- Not able to open core documentation in coregen.

- In the FIFO Generator GUI, after importing an XCO file (Independent clock, distributed memory configuration) into a Virtex-4 CORE Generator project, if the FIFO type is changed to "Independent Clocks, Built-in FIFO" in page 1, page 2 does not correctly offer the Read Clock Frequency and Write Clock Frequency options as it should.

- CR 467240

- AR 31379

- When using Common Clock Built-in FIFO configuration with asynchronous reset for Virtex-6 FPGA, correct behavior of the FIFO status flags cannot be guaranteed after the first write.

Workaround: To work around this issue, synchronize the negative edge of reset to RDCLK/WRCLK.

For more information and additional workaround see Answer Record 41099.

- The FIFO Generator GUI is allowing the user to select the FULL Threshold Assert Value lesser than EMPTY Threshold Assert Value for AXI FIFO.

- CR 613264

Workaround: To work around this issue, select FULL Threshold Assert Value greater than EMPTY Threshold Assert Value
