SYNTEST: an environment for system-level design for test

The authors describe the design and implementation of SYNTEST, a system for the design of self-testable VLSI circuits from behavioral description. SYNTEST consists of several algorithmic synthesis tools for scheduling, testable allocation, and optimum test points selection. A key feature in SYNTEST is the tight interaction between the system tools: the scheduler, the allocator, and the test tool. The system uses a technology library for optimizing the original structure. All tools interact with each other as well with the user through an X graphical interface. This provides a better design environment and allows for more designer intervention.<
