Hi all, I'm about to buy a Pro to replace an existing Spartan 6 design. I'd like to have a 4 digit 7 segment LED display and 8 toggle switches. The LogicStart MegaWing looks just right but I have one problem. I need 6 free pins (not including ground) for 3 instantiated uarts but the MegaWing uses every pin on the Pro so I am out of luck. Does anyone have a recommendation for how I can get my LED display, toggle switches and free pins? I can always connect the display and switched off board but will purchase existing products if possible. Thanks, Mr Minix
I've been working on a HDMI input wing, and have hit what looks to be a potential major snag. The TMDS input requires 50 ohm termination resistors to 3.3V on the differential inputs, at a "suitable distance" from the FPGA's pin. I am assumed that the rising edge is around 0.5ns for a 750Mb/s 1280x720p signal. That gives a 1/4th Transition Electrical Length is about 2cm, and using my trusty scrap of paper the trace from the chip to the top of the wing connector is about 5cm. So I am now worried that if I locate the termination that far from the FPGA it will adversely affect the signal integrity. Can anybody confirm if this worry is well founded or not?
