You might want to consider a new name - Zynq is Xilinx's flagship family of FPGA/ARM SoCs. With Xilinx being a pretty large corporation I'd be surprised if they don't immediately try to defend their trademark.
Now if you were Dell coming out with a Zynq line, that would be a different story.
Lawyers are as hungry these days as anyone else. They need to pick a new name, or at least a new domain name. It's a terrible name for SEO, if for no other reason.
If I were Xilinx and reading this thread. I'd be preparing the lawyers already. Just my two cents.
You should really consider renaming the product. Even if you don't want do, your product is going to loose the Google game, it will never popup when people will Google "Zynq", "Zynq planning", "Zynq trial", "Zynq API", etc... and if it does, Xilinx will sue you as soon as they notice.
I've worked for a startup before, whose name was systematically getting auto corrected by Google (it was too close to another word and was interpreted as a typo) and it made it really hard for people to find it even when they were specifically looking for it. In retrospective, they should have changed name. Don't do the same mistake we did.
Obviously that's not the feedback you were anticipating, so sorry about that. ^^
