The clock is the most important and special signal of the entire circuit. Most devices in the system are operated on the hop-on-line of the clock, which requires that the delay deviation of the clock signal be very small, otherwise, the timing logic status may be wrong. Therefore, it is very important to clarify the factors that determine the system clock in FPGA design and minimize the latency of the clock to ensure the stability of the design. 1.1

Not much understanding of the FPGA global Clock, thus reprinted a document:Http://xilinx.eetop.cn/?action-viewnews-itemid-42At present, synchronous sequential circuits are generally recommended for large designs. The synchronous sequential circuit is based on the design of Clock trigger, which puts forward higher requirements for clock cycle, duty ratio, delay and jitter. In order to meet the requirements of synchronous timing design, the design of th

FPGA-based 160-Channel Data Collection System Design Time: 09:50:21 Source: foreign electronic components Author: Wang yongshui, Ren Yongfeng, Jiao xinquan L Introduction With the development of science and technology and the national economy, the demand for electric energy is increasing, and the demand for power quality is also increasing. This poses a challenge to power quality monitoring. The monitoring of power quality usually requires multi-chan

ArticleDirectory Clock offset I. Area Structure Design 1. the folding assembly line can optimize the area of the assembly line design for the pipeline-level replication logic. The method of "folding Pipeline" is the opposite of "disassembling the loop", and is an area and speed interchange method. 2. shared logical resources sometimes require dedicated control circuits to determine which components are input to a specific structure. In some applications, resource input is often m

This network to multi-port module can easily realize the data transparent transmission between network equipment and multiple serial devices.This scheme is based on fpga+w5500. The serial port part uses the serial data to send and receive the hardware accelerator, make full use of the buff and FIFO resources, and greatly improve the data scheduling ability of 16 serial port. At the same time, the network part uses Toe technology's W5500, thus greatly

Application Specific intergrated circuits (ASIC) is an integrated circuit designed and manufactured according to the requirements of specific users and specific electronic systems. FPGA, short for field programmable gate array, is a field programmable gate array. It is a product of further development on the basis of PAL, gal, PLD and other programmable devices. As a semi-customized circuit in the specialized Integrated Circuit (ASIC) field, it not

Most FPGA developers are accustomed to graphical interfaces (GUIs). The GUI approach is easy to learn and provides a one-click process for small projects. However, as FPGA projects become more complex, in many cases GUI tools hinder productivity. Because GUI tools do not provide sufficient flexibility and control over the entire development process. On the other side, the GUI tool itself consumes a large am

The implementation of the Arduino and FPGA interaction, of course, there is no new protocol, or based on serial communication, now learn a serial communication can basically drive most modules, and with a variety of single-chip computer seamless data interaction, Arduino because of its powerful library function support, in the implementation of many things will be convenient many , such as serial communication, Arduino on two lines of code, Verilog at

Description A loop lattice is a matrix in which all the elements are arrows, pointing to adjacent four squares. Each element has a coordinate (row, column), where the upper-left corner of the element coordinates (0,0). Given a starting position (R,C), you can walk along an arrow line between the squares. That is, if (r,c) is a left arrow, then go to (r,c-1), if it is the right arrow then walk to (r,c+1), if it is the arrow then walk to (R-1,C), if it
