Simulink Library Development and Implementation for Vlsi Testing: Matlab Concepts for Vlsi Testing Balwinder Singh

In testing two important factors which are used to check the complexity level of the CUT (Circuit under Test) is COM (Controllability and Observability Measures). Normally for their calculations standard formulas are exist. But these formulas are different for combinational and sequential circuits. Also to carry out calculation manually for all elements in a complex circuits is very tedious job. To resolve this problem user libraries are developed and embedded in to Simulink. Then a GUI (Graphic User Interface) is developed in MATLAB as a front-end for the designed COM calculation models. The final calculated results are saved in the excel file, which works as a data base. In this way a frame work is designed. The Simulink based designed libraries are general purpose type. That is represented by designing some ICSAS-85 benchmark circuits by using custom libraries and results are calculated for them. And further the designed models and libraries can be used as class room teaching.
