André, Unfortunately it is not the only problem with ISE 11.1 - so far we failed to convert the project to that newer version, for this project I'm still using 10.1.03 (last time I checked it was still available at Xilinx)., but generally this is a problem when using non-free, closed source programs like Xilinx WebPack .
When I was starting to use this type of FPGA in 2002 I was choosing between the two major FPGA manufacturers that provided similar performance devices, and the other manufacturer had a 90-day license for their free-as-in-beer software. That meant that there was no guarantee that you will be able to work on your design after that time passed. So I decided to use Xilinx devices as even as they were not able to provide the software under any of the approved FOSS licenses their programs did not have expiration time that could jeopardize your development. Of course there are a lot of other inconveniences when using non-free software for the GPL-ed project, one is related to the simulation of the design. Even we use Icarus Verilog and GTKWave (both under GNU GPL) and Elphel code is also released under the GNU GPLv3, we need a few Verilog models of the device primitives, and these source files are non-free (so we can not re-distribute them) and they are "changed without notice" by the manufacturer. Some of these models of the primitives have problems with Icarus Verilog, so we need to patch them, and try to keep these patches current. I did hesitate to upgrade the project to the 11.x WebPack version - the import/export of the project in the text format is still possible in 11.1, but it is less straightforward to do that and I'm not sure that possibility will remain in the future releases. Additionally when I tried 11.1 version again I noticed a very alarming warning message: WARNING:Security:42 - Your license support version '2010.04' for WebPack expires in 8 days. Xilinx Web site ( http://www.xilinx.com/support/answers/33074.htm ) explains that the software will stay operational after the expiration, only the updates will be disabled, but still it seems that the major competitive advantage this manufacturer had for Elphel projects may disappear in the future. André, please check if you can get a compatible (10.x) version of the software at Xilinx, as of today it is the only that works with our code without tweaking.
