10.1 data2mem - I have an embedded design for the Virtex-4 FX12 or FX20 that used to work but no longer works in 10.1

Description

I have an embedded design for the Virtex-4 FX12 or FX20 that used to work but no longer works in 10.1. What can I do to resolve the problem?

解决方案

There was a bug where data2mem would not update the contents of block RAMs if they were in column 0, rows 0 - 8.

To resolve this problem, run BitGen in command line mode on the place and routed NCD file:

1. Open a command prompt in your XPS project's implementation directory.

2. Copy your executable.elf file into the implementation directory.

3. Run> bitgen -bd executable.elf system.ncd mod_download.bit system.pcf

Your bitstream should now contain the correct data.
