描述

A FIFO Generator v5.2 core targeting a Virtex-6 Built-In FIFO might fail to generate, with the following error message:

"ERROR:coreutil - XST has returned an error: ERROR:Xst:1631 - Data Corruption(Timing): Required time traversal failed on sequential element U0/gbiv5.bi/v6_fifo.fblk/gextw[1].inst_extd/gchain.gp1[2].gbldl.inst_prim/gf36e1_inst.sngfifo36e1:WREN(FIFO36E1)"

解决方案

This issue will be fixed in the next release of the tools in ISE 11.3. Currently, the only work-around is to target a block RAM-based FIFO.
