| Abstract: | In this paper the design of a portable logic analyzer is based on FPGA chip as the core of data processing and control system,using FPGA on-chip dual-port RAM for data storage, finite state machine to achieve a trigger control and display drive; then LCD12864 module to complete the terminal output graphic display. Moreover, on DE0 Nano FPGA （Altera Cyclone IV） development board the test results show that,the design of low-cost portable logic analyzer can achieve 8 channels logic combination triggering or 4 sequence triggering; also has 8 stage sampling rate preset regulation and the measured signal frequency direct readout. |
