Dear Github DMCA Team:

This firm represents Xilinx, Inc. (“Xilinx”) in connection with certain intellectual property matters. Xilinx
is a leading semiconductor, software, and hardware company with over $2.3 billion in annual revenues
(fiscal year 2014). Additional information about Xilinx, its products, and its corporate history is provided
at Xilinx’s website, www.xilinx.com. Xilinx’s offerings are founded on and used in connection with
numerous pieces of copyrighted material and trade secrets, including proprietary source code.

Xilinx recently learned that certain of its proprietary and copyrighted source code, passphrases, and
software “keys” have been made available on your website at https://github.com/hdlwriter/hdl_decrypt.
The copyrighted information appears to have been submitted by GitHub user “hdlwriter.”
I have a good faith belief that use of the copyrighted materials described above on the
infringing web page is not authorized by the copyright owner, or its agent, or the law. In fact, Xilinx has
taken substantial steps to protect this information, and is highly concerned by the presence of this
material on your website.

Therefore, we request that you immediately remove the entirety of the material posted detailed above.

I have read and understand GitHub’s Guide to Filing a DMCA Notice. Further, I swear, under penalty of
perjury, that the information in this notification is accurate and that I am authorized to act on behalf of
