Digital Discovery's high-level block diagram is presented in Figure 2, below. The core of the Digital Discovery 2 is the Xilinx® Spartan®-6
FPGA (specifically, the XC6SLX25-2 device). The WaveForms application automatically programs the Discovery’s FPGA at start-up with a
configuration file designed to implement a multi-function test and measurement instrument. Once programmed, the FPGA inside the
Discovery communicates with the PC-based WaveForms application via a USB 2.0 connection. The WaveForms software works with the
FPGA to control all the functional blocks of the Digital Discovery, including setting parameters, acquiring data, and transferring and storing
