AR# 33446
MIG v3.2, Virtex-6 FPGA RLDRAMII - "ERROR:Bitgen - Could not find programming information" occurs for the XC6VLX760-FF1760 device
Description
When generating a bitstream for the MIG v3.2 RLDRAMII design targeting a XC6VLX760-FF1760, the following error is output in the .bgn report:
ERROR:Bitgen - Could not find programming information for I/O standard DIFF_HSTL_II_T_DCI drive=-1, slew=*, master=*. The programming of the output buffers will not be correct.
Solution
This error can be safely ignored and does not affect the behavior of the RLDRAMII design in hardware. This is a false error reported by the tools and will be resolved in ISE Design Suite 11.4.
