R Design Trade-Offs Design Trade-Offs A few system-level design trade-offs were required in order to provide the Spartan-3E Starter Kit board with the most functionality. Configuration Methods Galore! A typical FPGA application uses a single non-volatile memory to store configuration images. To demonstrate new Spartan-3E FPGA capabilities, the starter kit board has three different configuration memory sources that all need to function well together. The extra configuration functions make the starter kit board more complex than typical Spartan-3E FPGA applications. The starter kit board also includes an on-board USB-based JTAG programming interface. The on-chip circuitry simplifies the device programming experience. In typical applications, the JTAG programming hardware resides off-board or in a separate programming module, such as the Xilinx Platform USB cable. Voltages for all Applications Related Resources The Spartan-3E Starter Kit board showcases a triple-output regulator developed by Texas Instruments, the TPS75003 specifically to power Spartan-3 and Spartan-3E FPGAs. This regulator is sufficient for most stand-alone FPGA applications. However, the starter kit board includes DDR SDRAM, which requires its own high-current supply. Similarly, the USB-based JTAG download solution requires a separate 1.8V supply.
