Fast calculation of analog circuits' feasibility regions by low level functional measures
S. Zizala, J. Eckmuller, Helmut Gräb · 2002
In this paper we present a new approach for fast calculation of analog circuits' feasibility regions. We use low level functional measures to assure the basic functionality of the considered circuit. These are approximated to give a fast estimate of the region, in which non-pathological behavior of the circuit is guaranteed. As this approximation can be complex, a method to reduce this complexity is proposed. With an example it is shown that this method reduces the originally specified definition region by 70%. Furthermore we show that using the feasibility region as a definition region for circuit-modeling significantly increases the accuracy.
