outline INTRODUCTION AN ILLUSTRATIVE EXAMPLE THE MATCHING PHASE THE REPLACEMENT PHASE MATCH-AND-REPLACE ECO ENGINE EXPERIMENTAL RESULTS CONCLUSION
INTRODUCTION Functional ECO has been an indispensible technique in modern VLSI design flow. An engineering change order (ECO) approach that aims at rectifying the design problems after synthesis and optimization.
THE MATCHING PHASE rectification pairs : – A group of pairs are rectification pairs if and only if replacing all no in these pairs with their ng makes the original and the golden circuits turn into functionally equivalent.
THE MATCHING PHASE Cut function : – A Cut function in a circuit Cir,represented as CFCir(CUT), is a modified output function of Cir which its input signal are moved from the PIs of Cir to the cut CUT.
