1. Flow of signals carried by FPGA at the board level. Generally, the strip of a Board follows the signal stream. from one side to the other side, it may be bent, but it will not return. FPGA pins are allocated. This principle should also be followed to avoid wiring, such as crossover and surround. 2. FPGA internal bank. Be familiar with the internal distri

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

There are a lot of resources in the library. Here we will also make a brief record. If you work in the future, you will need to use previous knowledge for future reference. I will also give a brief introduction to books.

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

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

For example, many manufacturers provide the design of the ASIC Gate array, but the above lead layer design can be defined according to customer design to achieve custom logic, this kind of ASIC refers to the main generation.FPGA is a programmable array, the use of a lookup table str

-clock pin, which is the ILA logic.In S6, it is recommended that the global clock output only connect to the clock pins, otherwise it is difficult to cause cabling problems easily. The constraint of adding clock_dedicated_route can reduce this error to alarm and continue to run layout and cabling. It is important to note that this constraint does not force the CLK_WE signal to pass through BUFG, but rather tells the tool to ignore such non-optimized clock resource usage issues. You can see throu
