Perhaps this is it, perhaps it's not just the signal integrity, the EMC, the mechanical constraints or for that matter how it's going to fit into the case It's all of it. In actual production environments and industry, PCB design and signal integrity issues like impedance mismatch are done and checked using software like PADS and Allegro. If you haven't already read it, hottconsultants.com/techtips/pcb-stack-up-1.html provides a very good overview of tradeoffs among stackup choices various numbers of layers – vicatcu Jan 17 at 19:35 So long as you pay attention to trace impedance, signal return paths, and all of the other usual signal integrity things then you can really do anything with the stackup. PCB design isn't playing with coloured lines to join the dots. Of course, some stackups make it easier to do I have done several PCIe designs and what I do is this:. I' m currently designing the PCB that has to be limited to 2 layers and I have a few problems I would like to share with you: 1) The split Ground Plane thing. Keep clock traces as straight as possible. But using multiple FPGA implies multichip design and there are several issues which need to be taken care. Because today's high density CMOS High-Speed PCB Layout Design Guidelines for Signal Integrity Improvement. When designing the PCB, contradictory goals of power delivery with high integrity and bi-directional signal integrity need to be balanced. By simultaneous I/O design planning and FPGA placement by both the teams important objectives like meeting of overall timing (both FPGA in-chip and on board), meeting of PCB signal integrity constraints, less number of PCB layers and less PCB area can be achieved. Printed circuit board (PCB) layout design becomes more complex for high-speed system design with high frequency and higher device pin density. I know I have to separate analog Others say that it is better if the analog and the digital signals are just running across separate areas, using a common Ground Plane and they also claim that a split Ground Plane causes a lot of signal integrity problems instead of solving them. A successful high-speed board must effectively integrate the devices and other elements while avoiding signal transmission problems associated with high-speed I/O standards. The thicker the PCB, the more vias become transmission-line stubs that degrade signals because they can radiate interference and cause signal reflections. The FPGA I/O design and placement of FPGA on PCB. Several of these issues can be .
