چکیده
Activity in Sequential Logic Circuits Jos e Monteiro, Srinivas Devadas Department of EECS, MIT, Cambridge Bill Lin IMEC, Leuven Abstract We describe a computationally e cient scheme to approximate average switching activity in sequential circuits which requires the solution of a non-linear system of equations of size N , where the variables correspond to state line probabilities. We show that the approximation method is within 3% of the exact ChapmanKolmogorov method, but is orders of magnitude faster for large circuits. Previous sequential switching activity estimation methods can have signi cantly greater inaccuracies.
