FPGA adopts the concept of logical unit array (LCA), which includes the configurable logic module CLB (Programmable Logic block) and output input module IOB (input output block) and interconnect. FPGA is a programmable device. Compared with traditional logic circuits and gate arrays (such as pal, gal, and CPLD devices), FPGA has different structures.

Broadly speaking, FPGA configuration includes programming the FPGA device using the download cable, programming the external EEPROM and flash, programming the FPGA device using MPU, and programming the device using the external EEPROM and flash. FPGA Devices are configured in three categories: Active configuration,

this transceiver has helped us implement clock data extraction units, synchronous character source and synchronous character detection modules, and analog front-end modules. What we need to do is how to configure this transceiver. In addition, an important task of the physical layer is to use the OOB (out of band) signal to identify the device and initialize the device upon power-on. Therefore, the physical layer module is further divided here to obtain the following physical layer diagram. The

1. CPLD or FPGA FPGA is suitable for completing time series logic, and CPLD is suitable for completing various algorithms and combination logic; The timing delay of CPLD is even and predictable, while the wiring structure of FPGA determines the unpredictability of the delay; FPGA is more integrated than CPLD an

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

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
