Previously, we introduced how to create a logic analyzer and oscilloscope using RP2040. Today, we will build a logic analyzer using FPGA. Currently, the mainstream architecture of logic analyzers in China is based on FPGA + USB PHY. The combination of the advantages of FPGA and the high accessibility of USB has kept it in … Read more
Whether you are developing microcontrollers or FPGAs, a protocol analysis tool – the logic analyzer, is often used. Unlike oscilloscopes, it can only collect digital signals, with sampling rates typically ranging from hundreds of MHz to GHz, supporting multiple channels for simultaneous sampling. The accompanying software supports parsing dozens of protocols such as I2C, UART, … Read more

Hello, hero! Welcome to the FPGA technology realm. The world of technology is vast, and meeting you is a fate. You can follow FPGA technology to get other interesting resources in the “Adventurous Journey” and “Chivalrous Acts” sections or enjoy a drink and chat together. “Enjoying a drink” enters the IC technology circle, where there … Read more
A Dual-Shoulder Backpack How Difficult Is It? Give It a Try! →_→ Long Press Recognition Circuits synthesized from FPGA are located inside the chip, making it nearly impossible to measure signals using oscilloscopes or logic analyzers. Therefore, manufacturers like Xilinx have invented built-in logic analyzers. In Vivado, this is called ILA (Integrated Logic Analyzer), whereas … Read more
Click the blue text above to follow us The logic analyzer is an instrument that collects and displays digital signals from the test device using a clock, primarily for timing judgment. Unlike oscilloscopes, which have multiple voltage levels, logic analyzers typically display only two voltages (logic 1 and 0). After setting a reference voltage, the … Read more

In a previous article, we introduced a logic analyzer built using a serial port. Today, we will discuss a logic analyzer based on USB2.0+FPGA. Before we begin, let’s introduce a logic analyzer’s host software – sigrok. Without good host software, even if the hardware is built, the experience will not be good. sigrok Here is … Read more
This series will bring systematic learning of FPGA, starting from the most basic digital circuit fundamentals, with the most detailed operational steps and straightforward language descriptions, providing a “foolproof” explanation. This allows students majoring in electronics, information, and communication, as well as newcomers to the workplace and professional developers looking to advance, to have a … Read more
