Make a PWM Driver for FPGA and SoC Design Using Verilog HDL

Make a PWM Driver for FPGA and SoC Design Using Verilog HDL

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.

The Best FPGA Development Boards for New Designers

The Best FPGA Development Boards for New Designers

Here's a rundown of three boards best suited for beginning to intermediate FPGA designers. Some boards cost thousands of dollars, and it’s unrealistic to compare a board of that cost to a board that a hobbyist would likely choose, so this comparison looks at three popular boards in the sub-$90 price point.
