<p>I got a <a href="http://www.celeritous.com/estore/index.php?main_page=product_info&cPath=1&products_id=129">USB JTAG Programmer</a> from Celeritous. And it took me the whole day to setup it in Linux. It seems that there is a <a href="http://forums.xilinx.com/xlnx/board/message?board.id=OtherSilicon&thread.id=76">bug</a> in Xilinx ISE Impact 10.1.</p>
<p>Now, verification times will be much shorter!!</p>
