01 JTAG (Joint Test Action Group) is an international standard testing protocol (IEEE 1149.1 compliant) primarily used for internal chip testing. Most advanced devices now support the JTAG protocol, such as DSPs and FPGAs. The standard JTAG interface consists of four lines: TMS (Test Mode Select), TCK (Test Clock Input), TDI (Test Data Input), and … Read more

Source: FPGA Resource Hero In the process of FPGA development and learning, a critical step is the board download implementation. Achieving hardware “hard realization” is crucial, and generally, the JTAG interface is more commonly used. Therefore, many experts must have encountered issues with the JTAG interface malfunctioning or being damaged and unusable. Recently, I faced … Read more
1. Design Overview This design implements a multi-channel UART/SPI communication system, capable of one-to-many communication. The system can operate in UART mode or SPI mode. The reason I chose this topic is mainly that my current laboratory needs to write a fast communication system based on UART. This topic can help solidify my previously learned … Read more
