Abstract
A simulation environment is disclosed wherein both analog and RF signals are simulated in a single flow by a mixed-domain simulator. The simulator includes a simulator kernel with an analog solver and an RF solver to allow both analog- and RF-type of signals to be solved in an interrelated fashion. The simulator may also include a partitioner that divides the circuit into various RF and analog modules to be solved. User input may control the partitioning process, but the simulator may refine the partitions or generate sub-partitions to provide a higher probability of convergence.

21. A method of simulating a circuit, comprising:
-
reading a description of the circuit that includes a list of components in the circuit and the interconnections between the components, the circuit including both a first set of nodes and components responsive to time-domain signals, including analog signals that are not modulated, and a second set of nodes and components responsive to time-frequency domain signals, which include RF signals, which are modulated; and in a single simulation flow, simulating the time-domain representations of signals, which are not modulated, on the first set of nodes using a first set of non-linear equations and simulating the time-frequency domain representations of signals, which are modulated, on the second set of nodes using a second set of non-linear equations; the single simulation flow including interrelately solving the first set of non-linear equations, and the second set of non-linear equations, until convergence. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
