IntroductionThe AXI protocol is probably a protocol that we often encounter in our usual circuit design, and it's a good deal, and we'll be familiar with this section.At first glance, the AXI protocol signals are numerous, dazzling and easy to Fameng. But in fact its basic idea is very simple. Just grasp the following points:1,valid/ready protocolThe Axi protocol is a typical bus protocol based on the Valid
Digital Integrated Circuit Design-15-DPI (continued)Introduction
For SV, both constructing test incentives and simulating parallel behavior of hardware, DPI is very convenient. The last time we introduced how to import and call the C function through "import" in SV.
In this section, we use a simple example to illustrate how C functions call SV tasks and function

3.1 experiment 7: digital tube circuit drive
If you have studied single-chip microcomputer, do you know more or less about digital tubes?
Circuit Design: This is a very big concept, from the voltage intensity can be divided into strong electric circuit design and Weak Current Circuit Design; from the design tool can be di
RequirementsThe operating process of the digital circuit is briefly simulated, and the potential (simplified to L and h) is realized by C # WinForm.Logical part of thinking
The circuit is a graph structure, based on C # characteristics, Design node Class (node) and wire Class (Wired), and is generic.

A relay is an electronic co
Summary of simple digital clock designIn the information age, the concept of time is deeply rooted, so mastering the design of digital clock has certain epoch significance, and using Multisim to design digital clock for discrete components can greatly improve the quality of
The world is a digital reading after reading "The World is digital" Let me be more surprised, our lives are full of numbers, we live in the digital life, however, some numbers in the simple listen to nothing special, but "the world is Digital" in the book with vivid examples
Modern integrated op amps (op amp) and instrumentation Amplifiers (In-amp) offer a number of benefits to design engineers compared to discrete devices. Although many clever, useful and attractive circuits are provided. This is often the case because a hasty assembly of the circuit ignores some very basic problems, causing the circuit to fail to achieve its intend
PLC uses a ladder chart language that is extremely similar to the circuit diagram of the relay. If PLC is used to transform the relay control system, it is a shortcut to design a ladder chart based on the relay circuit diagram. This is because the original relay control system has been used and tested for a long time and has been proved to be able to complete the
1) MCU reset pin circuit design, general use of RC mode, please calculate the basis of RC selection value;2) The current circuit board design for 5V to 3.3V mode, Chip asm117-3.3, trouble to give the current circuit board power supply formula advantages and disadvantages, po
This article combined with my personal experience, through a simple example, to illustrate some of the characteristics of analog circuit design, I hope to engage in analog circuit design related direction of the students have some help.Theoretical knowledgeAnalog circuit nee

, physical structure and Moore's law interpretation, which makes me understand the basic structure of the computer, deepened the understanding and understanding of the computer. After introducing us to bits, bytes and information representations, this chapter gives me an idea of what I have never known before, such as the red liquid of a thermometer or the mercury column being simulated: the liquid expands or contracts proportionally with temperature changes, so that the temperature produces a s
use decimal? That's why people can understand it because high and low levels are not ideal for rectangular waves, only 1 and 0 are stable by high and low levels. 10, the current circuit is not able to accurately quantify, and the level is not ideal high and low jump change. The first use of the tube, with paper tape punch record data. Now the basic Integrated Circuit sub-TTL and CMOS two kinds. The most ba
Pay attention to the following basic items for the current loop:
1. If you use strip, try to bold it.
If the Grounding Connection on the PCB is to be considered, the design should be as rough as possible. This is a good rule of thumb, but you must know that the minimum width of the ground wire is the valid width from this point to the end. Here the "end" refers to the farthest point from the power connection end.
2. Ground loop should be avoided
After reading the book "The World Is digital", I deeply realized that the direction of future development will be digitized, and there are many unknown problems in this field waiting for us to explore. This book is very suitable for us now, as a soft courtyard students, this book let me know a lot of hardware, programm
