Abstract :
Along with the requirements of application, the mixed-signal circuit - LCD driver/controller has more output pins and gradation voltage levels, which makes the verification and test difficult. This paper builds a system-level verification platform for LCD driver/controller circuit, in this module we convert the simulation file for behavioral simulation to test patterns for auto test machine, and we can also use this simulation file to verify out controller circuit design. Some new technology for high precision test of LCD driver/controller and the structure of LCD tester are also described in this paper.
