traffic light interfacing with spartan 3 primer
The Spartan-3 board features a traffic light controller utilizing FPGA I/O pins. The traffic light controller card consists of 12 point LEDs arranged in 4 lanes. Each lane is equipped with three LEDs: Go (Green), Listen (Yellow), and Stop (Red)....
Combinational Logic Circuits using Logic Gates
Electronics tutorial on combinational logic circuits that utilize logic gates to create multiplexers, encoders, and solid-state switches.
Combinational logic circuits are fundamental components in digital electronics, characterized by their ability to produce outputs based solely on the current inputs, without any...
LEDs and Switches
The DE2 board features four pushbutton switches, each of which is debounced using a Schmitt Trigger circuit, as shown in Figure 1. The outputs, labeled KEY0 to KEY3, from the Schmitt Trigger are directly connected to the Cyclone II FPGA....
How to design 65nm FPGA DDR2 memory
This article discusses practical techniques for incorporating "correctness by design" in DDR2 interfaces from a Signal Integrity (SI) perspective, utilizing the current generation of available design tools. It analyzes common DDR2 design errors and the trade-offs between various popular design...
Reference designs for Series 1 FPGA Boards
ZTEX USB-FPGA Boards require three different voltages: 1.2V, 2.5V-2.6V, and 3.3V, which must be supplied externally. This can be achieved using Power Supply Modules, Experimental Boards, or a user-specific design. To facilitate development in the latter scenario, three reference power...
