An FPGA is a crucial tool for many DSP and embedded systems engineers. However, the learning curve when getting started can be fairly steep. This project introduces the Quartus II and ModelSim software suites as well as a background on FPGA design flow for system on chip development. The development board used was a Terasic DE1-SoC, which has the Altera Cyclone V SoC chip. This IC contains an FPGA and an integrated ARM Cortex A9 as a hard processor system.
