After debugging an FPGA board, it never works properly after power-on. Phenomenon: nstatus indicators are constantly flashing, and the tested LEDs (FPGA gpio) cannot be lit, that is, FPGA is not working properly. Debugging process: 1. After FPGA is powered on, it immediately sets the nstatus configuration stat

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

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

Through the analysis of MATLAB to verify the filtering effect, the audio signal of the superimposed noise signal is output to TXT file. Then use the Matlab language to write the filter module and test module, thr

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

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
