DescriptionRAM tracing using a Xilinx Spartan From Digilent.jpg |
The DSi board has about 50 tiny wires soldered to it, exposing all RAM pins (and other useful things, like power and SPI) to the row of headers. The FPGA (Digilent Spartan 3 with USB2 add-on) is ready to trace the bus. The BNC connector at the lower-right is an external clock input, so I can slow down the DSi in order to make it possible to stream the RAM traces without running out of USB bandwidth. |
