....register (LFSR) and the response analyser as a multiple input signature register (MISR) A built in logic block observer (BILBO) is a register which can operate both as a test pattern generator and a signature analyser. However, the disadvantage of using BILBOs is the large area and delay penalty [Wag96]. An advantage of using the BIST technique is that tests are performed at speed. The technique also has a lower test application time compared to the scan technique. Since the BIST technique does not require any special test equipment, it can be used not only for production test, but also for ....

....them, full or partial scan based techniques [15, 16] are commonly used. However, the area and delay overheads incurred in scan based designs are not always small. High test application time is also an area of concern in such designs. More recently, DFT techniques at the RTL have been proposed [3, 7, 17, 18]. These approaches selectively apply a DFT enhancement to a circuit ignoring possible benefits from a judicious application of a combination of these techniques. For example, the DFT approaches in [3] and [7] are based solely on test multiplexer addition and partial scan, respectively. We are, ....

....performs computation on data applied on data primary inputs. The controller sequences the normal flow of execution on the datapath. Even if the datapath is fully testable when considered in isolation, particularly if generated using a High Level Synthesis for Testability tool (see [1] and [2] for a survey) its testability can be strongly affected after connection to the control part. As a matter of fact, the controller implements only the normal flow of execution (system mode) As a consequence, the set of actual words on the control signals and the next state logic may limit the ....

....of some characteristics of the circuit, like performance and area. In order to mitigate these consequences, it has been proposed in the early 90 s to take into account testability at the beginning of design flow, namely during HLS. A survey of HLS for testability techniques can be found in [1], 2] A favorable step in HLS for solving testability problems is the register allocation binding phase. During this step a sufficient number of registers is determined for storing behavioral variables, and variables are assigned to accordingly. The large number of achievable solutions and the ....

....the number of primitive elements in the circuit is reduced, thus making the problem size more tractable. In recent years, various behavioral and architectural schemes have been proposed to generate easily testable sequential circuits. These techniques may target BIST, scan or sequential ATPG [2]. However, while targeting a circuit for testing, the behavioral description is not available in many cases. Solving the problem at the gate level suffers from the problems mentioned above. Hence, in order to get the testability advantages of a higher level of abstraction, the RTL merits ....

....RTlevel method was presented to generate self testable RT level data paths, using allocation and automatic test point selection to reduce the sequential depth from controllable to observable registers. A comprehensive survey of the behavioral and RTlevel test synthesis techniques can be found in [36]. Like the behavioral synthesis for testability techniques summarized above, all the existing RT level techniques are scan based and cannot generate testable data paths without the use of scan. C. Testability of Sequential Circuits The dependencies of the FF s of a sequential circuit are ....

....Test problems that cannot be fixed by lower level optimizations alone require additional design iterations, leading to increased design cycles. Thus, the benefits of high level design cannot be fully realized unless consideration of testability is also integrated into the high level design process [1]. A behavioral description contains an algorithmic specification of the design s functionality, and may contain little or no information about the design s cycle by cycle behavior or structural implementation. Behavioral synthesis tools typically compile a behavioral description into a suitable ....
