Hello, While I certainly do not condone piracy, and I believe Xilinx should be compensated for their hard work, sometimes it can be handy to run ISE without limitations on the range of targetable devices and without having to go through the rather annoying 30-day evaluation license generation. For the purpose of disabling the license checks, install ISE 14.7 (20131013) and make sure to create a ~/.Xilinx/Xilinx.lic (can be empty). With a hex editor, open /opt/Xilinx/14.7/ISE_DS/ISE/lib/lin64/libSecurity.so (md5: ba5974651af72b9296f76e40bc432679) and at offset 0x3EABA, which is the epilogue of Sec_Checkout, replace the two bytes 89 D8 with B0 42 (mov al, 0x42). The new md5 will be 3d29e8d3c00ea2bb5beb406bcb9df95d.

'FLEXlm is the most popular license manager used in the software industry. FLEXlm is best. There is a crack, a crack in everything That's how the light gets in. This article was inspired by the tutorial by SiuL+Hacky on how to crack XprismPro 1.0. The above program ran on Linux, but my target ran on Windows 95/NT. The aim of this tutorial is to expand on some of the ideas in the first tutorial and to detail the differences encountered on the PC.

This effectively bypasses te license verification, and restrictions on targetable devices will be lifted. --rwr KJ, 17:29 น.

Piracy: the act of reproducing someone's else (art) work without permission 2. Copyright infringement: unauthorized used of a copyrighted material. License: set of permission granted by the licensor to the licensee to use a product. By doing what you are doing you are certainly not promoting piracy, since there's no reproduction of any artwork in your 'advise'.

On the contrary you are suggesting you have more rights than the ones the licensor (Xilinx) gave you in the license. (I recall you that you accepted the license the very same moment you decided to use their software).

The reason why Xilinx issues the license the way it does and copyrights their products that way is because they consider that 'running ISE without limitations' is affecting negatively their business and they want to protect it. If you really believe you have the rights to 'run ISE without limitations' you can post your name and address so that any Xilinx representative here on the group may get in touch with you and kindly explain what are your rights and what are theirs. Or maybe you can simply give them a call and see what they think. That being said, I strongly discourage anyone in this group to follow such practices and stand against such advices. OTOH if the OP wants to work hard on a GPLed toolchain for fpgas in order to really be able to *run it without limitations*, I'd be more than happy to promote and contribute to that effort. Al Tomas D., 15:29 น. Dear all, agreeing with alb, this is a license breach issue and not promotion of pirating acts.

I agree; there is no other point to be made here; accepting a license for a licensable work is a binary decision. > OTOH if the OP wants to work hard on a GPLed toolchain for fpgas in > order to really be able to *run it without limitations*, I'd be more > than happy to promote and contribute to that effort. It would be great to see such an effort that many of us would contribute. If you are looking into a logic synthesis open-source project with a lot of potential, I would suggest YOSYS () by Clifford Wolf.
