In the embedded development and debugging, logic analyzer is a good aid for developers to finish tasks like breakpoint, triggering and tracking. The design of a 16-channel logic analyzer is based on Verilog HDL and FPGA chip. The design also has a multi-stage sampling rate, and applies a logic signal threshold voltage of 0.25 to 4V range of the logic level of the input signal by the age of 16-level changes.
