| Abstract: | A scheme of function test system for digital circuit boads based on USB bus technology is put forward in the paper. The system adopts AN2131QC chip that is produced by Cypress Company. We adopt ISP chip that is produced by Lattice as the key control portion of the whole system. Custom bus architecture is adopted in the system, at the same time the design of test resources followed modular, standard design idea. The whole system has the follow virtues, such as high reliability, expansibility, testability and so on. |
