Abstract
For the purpose of meeting electronic equipments' test demand, the design realized one Logic Analyzer with 64 sample channels and 8 trigger levels based on FPGA. Firstly, this paper realized trigger-cell being of complete trigger functions, including state-triggering, edge-triggering, compulsive triggering and marked triggering, then successfully builded trigger-cells array provided with multilevel trigger functions by using shift registers and user-defined data type-structural signal array. Each trigger-cell in array can be programmable controlled, so complex logical triggering conditions are realized in Logic Analyzer. Currently, the logic analyzer is used in the process of certain electronic equipments of auto test.关键词
