Abstract

In this paper, a design for debug (DFD) method that reuses test resources is proposed to reduce the debug cost in post-silicon validation. With the proposed method, the trace buffer is shared for embedded cores to capture the signatures of each core concurrently by reusing a test access mechanism. In this case, the depth of the trace buffer allocated to the core is reconfigurable and variable according to debug scheme. The experimental results indicate that the proposed DFD significantly reduces the debug time when the trace buffer is shared by cores in various debug cases.
