Design Error Diagnosis in Digital Circuits without Error Model
نویسندگان
چکیده
We describe a new method for design error diagnosis in digital circuits, that doesn’t use any error model. A diagnostic specific pre-analysis of the circuit extracts a subcircuit suspected to be erroneous. Contrary to other published works, here the necessary re-synthesis of the subcircuit need not be applied to the whole function of an internal signal in terms of primary inputs, but may stop at arbitrary nodes inside the circuit. As the subcircuits to be redesigned are kept as small as possible, the redesign procedure is simple and fast. Experimental data also show the high speed of the diagnostic pre-analysis.

Simulation-Based Design Error Diagnosis and Correction in Combinational Digital Circuits
This paper describes an approach to design error diagnosis and correction in combinational digital circuits. Our approach targets small errors introduced during the design process or due to specification changes. We incrementally use simulation to identify suspect nets, and then attempt correction based on our error model. We use multiple iterations to handle multiple errors. Experimental resul...
متن کاملDesign Error Diagnosis in Digital Circuits with Stuck-at Fault Model
In this paper we describe in detail a new method for the single gate-level design error diagnosis in combinational circuits. Distinctive features of the method are hierarchical approach (the localizing procedure starts at the macro level and finishes at the gate level), use of stuck-at fault model (it is mapped into design error domain only in the end), and design error diagnostic procedure tha...
متن کاملOn efficient error diagnosis of digital circuits
The rising trend in large scale integration and design complexity has greatly increased the need for efficient design error diagnosis. We present techniques for fast and efficient error diagnosis of digital circuits by eliminating to a large extent the set of false candidates identified by the diagnosis. The elimination of false candidate regions is conducted via distinguishing X’s, flipping of...
متن کاملDesign error diagnosis and correction via test vector simulation
With the increase in the complexity of digital VLSI circuit design, logic design errors can occur during synthesis. In this work, we present a test vector simulation based approach for multiple design error diagnosis and correction. Diagnosis is performed through an implicit enumeration of the erroneous lines in an effort to avoid the exponential explosion of the error space as the number of er...
متن کاملFilter Based Diagnosis for Multiple Design Errors
Both due to the increasing complexity of VLSI circuits and due to the increasing trend to design automation, error diagnosis of digital circuits becomes more and more important. In this paper we present a filter based approach to diagnosis of multiple design errors. Although we present an exact solution to identifying the error location, experimental results show the efficiency of our approach....
