combination of hardware and software. Therefore, the occurrence of a failure depends on the timing, and the reproducibility is low. As a result, there is a problem that it takes time to obtain the information necessary for failure analysis. In addition, the entire system will be analyzed. Therefore, there is a problem that it takes time to analyze the trace result. Therefore, we propose a failure analysis environment consisting of three functions to solve the above problem. They have the following three functions. 1) The proposed environment has a long-time trace function to reliably acquire analysis information of failures with low reproducibility. 2) Bottleneck analysis function that aims to improve the analysis efficiency of trace results, 3) Function that facilitates understanding of analysis information. This failure analysis environment has been applied to six products in sequence from the development of the digital television HR-01 series. And above environment is still being applied to some product development. Also, as an example, the trace capacity was increased from 10MB to 190GB, and the failure analysis time was reduced by 94.8%.
