Abstract :
An algorithm is found for the time-domain analysis, of large-scale mixed analog/digital analysis of large-scale mixed analog/digital circuits. First, a set of basic IC functional blocks with their macromodels are defined. Then the concept of generalized node and the method of deriving generalized node equations of circuits are given. Finally, a selective trace iterative method used at the generalized node level to solve the generalized node equations is discussed. Four examples and their simulated results obtained using MIXMOD, which was developed with the authors´ algorithm, are given
