It is a semi-custom circuit in the field of ASIC, which solves the shortcomings of the custom circuit, and overcomes the limitation of the original programmable device gate circuit.Since the

Two articles I accidentally saw in the morningArticleBecause the development of the next version of coolui is about to begin. In order not to be distracted, the blog will not be updated before the next version is completed, however, I really like this article-a new trend that is not noticed by us outside of sight; In the era of deep sub-micron, traditional materials, structures, and even processes are moving towards extreme conditions, and Moore's Law is somewhat stretched. In the era of Deep

Typical FPGA development process and precautions The FPGA design process is the process of developing FPGA Chips Using EDA development software and programming tools. Typical FPGA development processes generally include function definition/device selection, design input, function simulation, comprehensive optimization,

Recently, some FPGA boards (ep4ce30f23c8n) were maintained, and we found that there were a pair of ground-to-ground short circuits for both 3.3v and 1.2v FPGA boards. After removing some chips powered by 3.3v, they were still short-circuited, there is no way to simply remove the FPGA chip. As a result, the short-circuit phenomenon disappears. It turns out that th

FPGA is currently very popular, and various colleges and universities have also opened FPGA courses, but FPGA is not suitable for everyone. What FPGA focuses on is an entry path and what path to accessThat is to say, in the electronic design process, you have to start from the electronic design, and then learn

Label: Ar data sp c time algorithm r Application Programming The essence that spld, CPLD, and FPGA can implement any logic is that any logic can be expressed (or approached) by polynomials ). Polynomials are nothing more than multiplication and addition operations. And exactly, match the door, or match the door plus. FPGA extended architecture: the on-chip programmable system. There are two types: one i

What is an FPGA? FPGA is a field programmable logic array, composed of programmable logic resources (LUT and REG), programmable wiring, and programmable I/O. The basic structure of Xilinx FPGA is the same, but with the development of semiconductor technology, FPGA's logic capacity is more and more rich, faster, embedded more and more hard core, such as: ARM proce

I have been fascinated by the internal resetting of FPGA. I have carefully studied the official data manual over the past two days. I have understood many of my doubts and I feel that I have made some progress ..... I. About POR (power-on Reset) When FPGA is powered on, it first enters the reset mode, clears all Ram bits, and sets user I/O to three States through the internal weak pull-up resistor. The co

FPGA at present very fire, each university also opened the FPGA course, but FPGA not everyone is suitable, FPGA is fastidious is a humanely, into what way, into the electronic design of the Tao, that is, this process, you have to start from the electronic design, and then learn the

I. field programmable gate array (FPGA) features high capacity, strong functionality, and high reliability.CommunicationIt is widely used in the system. Using FPGA to design digital circuits has become one of the main design methods in the field of digital circuit systems.

FPGA and Simulink combined real-time loop series-openingToday, the FPGA development process is bound to involve a process: verification simulation, validation in many cases is done in MATLAB, and most of the simulation of the beginners are using Modelsim simulation software. For example, design a signal filter module, verify that the filter module is in MATLAB design verification, the module design paramete

Ethernet switches are still quite common. So I studied how to use FPGA to achieve Ethernet switch networking perfectly. Here I will share it with you, hoping it will be useful to you. Ethernet networking is one of the fastest growing technologies in the industrial market. Most industrial Ethernet standards use the IEEE 802.3 standard Ethernet protocol. Therefore, these networks can transmit standard network services and real-time data. However, each s

The test module is created in Simulink, the signal is generated by the test module, and then transmitted to the FPGA,FPGA readout before the signal is not processed back to Simulink for display. This is to test that the entire hardware is functioning properly in the ring and is familiar with the entire underlying development process.Create a model to create a Devel

Altera's-6,-7,-8 speed level reverse order, Xilinx speed grade forward sort.Not very strictly, "the lower the number, the higher the speed level" This is the Altera FPGA sorting method,"The higher the serial number, the higher the speed level" is the Xilinx FPGA sorting method.Since then, I have not been able to understand how the speed grade, the only concept is: the same chip can have multiple speeds, dif
