| Abstract(in English) | Built-in Self Test (BIST) is one of effective methods for testing today's verylarge-scale SoCs. In BIST scheme, a test pattern generator (TPG), which generates test vector sequences fed to cores-under-test, must be embedded into SoCs. In this paper, we target the testing of SoCs with multimedia cores and introduce a scheme to utilize an image decoder, e.g., JPEG decoder, included in the multimedia cores as an embedded TPG. This scheme does not require additional embedded TPGs, so that it can reduce the hardware overhead of BIST methods. Moreover, we propose a method for generating seeds (or initial values of TPGs) in the case where a JPEG decoder is utilized as a TPG. The proposed seed generation algorithm can generate effective seeds, which are small in data size and can be decompressed to test sequences with high fault coverage. Experimental results show that, compared with a previous BIST method, the proposed method can achieve comparable fault coverage with smaller seeds and shorter decompressed test sequences. |
