....only valid within a limited range of design points. In this paper we present an alternative to the expression based approach, based on an exact representation of determinants as a graph or determinant decision diagram (DDD) a concept which was introduced to the linear circuit analysis domain in [10, 11, 12]. Instead of calculating the circuit output explicitly, the Laplace expansion of the circuit matrix minor is modeled in a DDD, which is discussed in section 2. This setup needs to be done only once for a given circuit topology, and is similar to the MTDD approach followed in [12] In section 3 we ....
....1 includes results for . maze circuits, which are networks with an impedance between each pair of nodes; RC ladder circuits, like the illustrative circuit ladder002 in Figure 1. These circuits have tridiagonal matrices, which renders the DDD setup a linear function of n as is explained in [11]; and opamp like circuits of increasing complexity. Note that for some maze circuits, SADAMAC did not generate any results. Term generation was limited to a fixed number of terms per coefficient, with an exception for the complex 741 circuit, for which only a few coefficients were ....

....which increases the CPU time for MTDDD construction. 6. Conclusions A new graph based approach, based on Multi Terminal Determinant Decision Diagrams (MTDDD s) is presented to semi symbolic analysis of analog integrated circuits. MTDDD s are inspired by the success of BDD s [8] DDD s [4 5], and MTBDD s [9] A computer program that implements the proposed approach has been developed and tested on a set of benchmarks. Experimental results have demonstrated that the MTDDD approach exploits the expression sharing and sparsity, while considering naturally both symbolic parameters and ....
