content: Hello, I want to integrate zynq 7z010 SOC on a PCB with Altium Designer. I must générate the soc Zynq 7z010 component and schematic to route it with the necessairy elements but I am new to FPGA on PCB design and I need healp in this step and i will be grateful

content: The Zynq's are all fine pitch BGA with hundreds of balls. Truly you're in at the deep end. Which device package are you planning to use? Whatever, you should be reading UG483 "7 Series FPGAs PCB Design Guide" first before you fire up your design software.

content: Avnet supplies several kits using the Xilinx Zynq. Seewww.zedboard.org. Avnet gives the designs away for these boards including the PCB files which you can copy or use as a starting point for your own design. As mentioned, the PCB layout is not trivial for these parts, many of traces must be equal length and have controlled impedance, clocks of many hundreds of MHz are common, not for the faint of heart. Avnet sells many of these boards as SOMs, so all the hard stuff is done, you just have to design the mother board. I've had good success with many of them, and the new Xilinx Vivado tools are awsome. (BTW I'm in no way affiliated with Avnet.)John

content: There are probably a handful of people on the word, who can help you with that task. To be honest, if I would be one of them, I would kindly send you a contract, and charge you the usual engineering contracting hourly fees. This is like asking someone to paint your house, please.If you have a supplier, contact them. Maybe they give you an appointment with an application engineer at xilinx.

content: Your best hope is to buy a small board containing the Zynq plus decent high-speed connectors and good grounding. These are typically called "mezzanine boards", and you would build a "carrier board" containing your i/o components and connectors for the mezzanine board.If you do not understand why a "high speed connector" and "good grounding" are necessary, you should not be designing a PCB with an FPGA.

content: Quote from: diyaudio on July 30, 2015, 09:29:18 amYes, they are made in a reflow oven. The temperature profiles and the stencils heve to be controlled more accurately. Also, at the end you need an X-ray to check if the soldering is OK. I personally, would use a module from a trusted ODM manufacturer, if I ever need to touch something like this BGA (well at least for a couple of years).
