It is well known that people have defined three basic logical relationships: AND, OR, NOT, which can be combined to form NAND, NOR, XOR, XNOR five logical relationships. All logical relationships in digital systems can be realized using the basic three logical relationships (similar to how decimal numbers can always be represented using 10 digits … Read more
Spirit stones arrange the universe, secrets hidden in logic gates.Two-dimensional matrices convey profound principles, the art of mechanisms reveals its power. In the late-night scripture hall, candlelight flickers as Liu Ru Yan and Elder Liu Mo Ran sit around an ancient wooden table, deeply studying the ancient texts of the Immortal Alliance’s mechanism hall. “Master, … Read more
This note records my learning process of FPGA, briefly documenting some knowledge points that may not be very clear or are worth recording for future reference. If the content of the notes happens to help you, I am very happy! 1. What is a Digital Circuit In life, there are two concepts: digital signals and … Read more
Analog Signal refers to information represented by continuously varying physical quantities, such as temperature, humidity, current, voltage, etc. Its value changes continuously and can take an infinite number of different values within a certain time range. Digital Signal has discrete, non-continuous values and is commonly represented by 1 and 0 in binary. In digital circuits, … Read more
From the perspective of underlying hardware, this article analyzes how the CPU recognizes and reads code. The content is so fascinating that after reading it, I felt that many things I learned suddenly connected together. I wanted to share it with everyone. Let’s first talk about semiconductors. What is a semiconductor? It is something that … Read more

4.1 FPGA Implementation of AND and OR Logic This section will design an AND and OR interface as shown in Figure 1.1, primarily implementing the logic AND and OR functions. The AND and OR interface includes 3 modules: clock stimulus, reset stimulus, and the AND and OR module. Figure 1.1 Block diagram of the AND … Read more
