PCB design

Well, I've spent a long time on this, but I think I'm pretty happy with the layout now. Tomorrow, I'll hopefully resize all the power lines a bit and add some ground planes...



I'm amazed how long PCB design takes... Still, the end result should be good. It's got scart, 2 joysticks, tape in, USB (with about 10 dedicated pins to the atmel which should provide serial, misc I/O and JTAG), PS/2 keyboard, SD card and a bunch of expansion headers offering 14 I/O. Additionally, there's another 4 lines from each of the FPGA and atmel tied together so the atmel can access the SD card via the JTAG which could also be used as general purpose I/O.

Let's hope that when I get this board made it actually works...

PCB designs grow increasingly complex and challenging with each technological advance. PCB design software helps companies meet market demands, facilitate global collaboration, accelerate time-to-market, increase profit margins, and optimize PCB reliability. Thanks a lot.
