| Research Abstract |
We developed a test method and its testable design methods for digital to analog convertors(DACs) implemented in SoCs(System-on-Chips) by measuring supply current. Also, we evaluated the testability of the test method and area overhead of the testable design methods. The results show us that a DAC in an SoC can be tested with a smaller number of test vectors by our supply current test method than a functional test one and the area overhead is not so large.
