SIMULINK MODEL FOR CONTROLL ABILITY AND OBSERVABILITY OF VLSI CIRCUITS

Gurinder Pal Singh and Balwinder Singh

This paper determines the controllability and observability in MATLAB/simulink, which is very easy way for handling complex VLSI circuits. As the complexity of VLSI circuits is increasing, calculations for controllability and observability by mathematical formulas is becoming tedious job for each and every gate in a complex circuit, and further if circuit is sequential then additional mathematical calculations for flip flops are required. To reduce the calculation complexity for user, two custom libraries are created, one for combinational circuits and another for sequential elements. Then a user interactive environment a GUI (Graphic User Interface) in MATLAB is presented, for forcing the inputs from outside of the simulink. Combinational and sequential circuit of each type is modelled with user custom library and controllability and observability of these circuits is verified.
