Abstract: The honeycomb-like rapid embedded system platform (HLRESP) is a kind of general-purpose platform based on field programming gate arrays (FPGA). It has a modularized and honeycomb-like structure. According to the feature of HLRESP, design for testability methods based on boundary scan technology are applied to the board level and system level design. The structure of boundary scan chain can be configured flexibly. Boundary scan test as well as in-system-programming(ISP) for programmable logic devices can be implemented. This gives facilities to test and debug the HLRESP, and development period of the system can be effectively shortened.
