HDL-A is an analog version of the Hardware Description Language which is suitable for structural and behavioral descriptions and simulations of digital, analog, and mixed-signal circuits and systems. This paper presents an automatic testprogram generator (ATPRG) for fault diagnosis of analog/mixed-signal integrated circuits. The ATPRG is developed under the Mentor Graphics design system environment, where the units under test (UUT's) are modeled in HDL-A and simulated by Accusim, and AMPLE (Advanced Multi-Purpose Language) in Mentor Graphics Design system environment is used to define and execute the generation process automatically. To increase the reliability and quality, the generated testprograms mill be verified and validated, A verification process checks if the testprograms are generated correctly and if the generated testprograms can effectively locate fault(s), The testprograms are validated by emulating the UUT's. The actual test can be run in a fully automatic mode, or interactively.
