Abstract (in Japanese) (See Japanese page) 
(in English) Test point insertion methods to reduce the number of test patterns have been proposed for test cost reduction of VLSIs. Test point insertion methods at gate level requires an enormous amount of time to identify signal lines to insert test points for large circuits. Additional multiplexors make them damage timing optimality by logic synthesis. Thus, test point insertion methods at RTL is required. In this paper, we propose a test register allocation method for concurrent testing of functional units in scan testing using RTL test point insertion. Furthermore, we propose a controller augmentation method for guaranteeing the behavior. Experimental results show that our proposed method which is the combination of the test register allocation method and the controller augmentation method reduced the number of test patterns by 17 % on the average for benchmark circuits of high-level synthesis.
