In this paper we present an e cient test{vector simulation approach for multiple design error diagnosis and correction. We also compare the quality of test vector simulation and BDDs for this problem and show the competitive performance of the former. Experimental results exhibit the robustness of our approach and con rm the theoretical results.

A Fast Algorithm for Locating and Correcting Simple Design Errors in VLSI Digital Circuits
With the increase in the complexity of VLSI circuit design and the corresponding increase in the number of logic gates on a chip, logic design errors can frequently occur. In this paper we present an eecient approach to Design Error Detection and Correction when a small number of modiications can rectify the design. Our method is based on test vector simulation and Boolean function manipulation...
متن کاملSpice Compatible Model for Multiple Coupled Nonuniform Transmission Lines Application in Transient Analysis of VLSI Circuits
An SPICE compatible model for multiple coupled nonuniform lossless transmission lines (TL's) is presented. The method of the modeling is based on the steplines approximation of the nonuniform TLs and quasi-TEM assumptions. Using steplines approximation the system of coupled nonuniform TLs is subdivided into arbitrary large number of coupled uniform lines (steplines) with different characteristi...
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....
