What are Digital Circuits? Digital circuits are electronic circuits that operate on discrete, binary signals. Unlike analog circuits, which work with continuous signals, digital circuits deal with signals that have only two possible states: high (1) or low (0), also known as true or false, respectively. These binary signals are represented by different voltage levels, with a high signal typically corresponding to a voltage close to the circuit’s supply voltage, and a low signal near Read more…

What are CPLDs? Complex Programmable Logic Devices (CPLDs) are integrated circuits that consist of multiple programmable logic blocks interconnected by a global interconnect matrix. CPLDs are designed to implement simple to moderately complex digital logic functions and are characterized by their fast pin-to-pin speeds, low power consumption, and ease of use. CPLD Architecture The architecture of a CPLD typically consists of the following components: Logic Blocks: CPLDs contain multiple logic blocks, each consisting of a Read more…
