Abstract: Some embodiments provide a method of simulating an electrical circuit that receives a circuit description that has a set of sub-circuits. The method defines several partitions for several sub-circuits. The method then simulates the circuit using the partitioned sub-circuits. In some embodiments, the method ranks the sub-circuits prior to partitioning based on a parent-child relationship that shows how a sub-circuit is instantiated by other sub-circuits. These embodiments partition child sub-circuits first. Some embodiments provide a method of partitioning an electrical circuit that has a set of sub-circuits. For a particular sub-circuit that is instantiated from other sub-circuits, the method duplicates the particular sub-circuit into a first copy and a second copy when one port of the particular sub-circuit is connected to a voltage source in at least one instance and the same port is not connected to a voltage source in at least another instance.

Abstract: Some embodiments simulate a mixed-signal circuit design by adaptively applying multiple simulation engines at various regions of the design at various stages of the simulation. Some embodiments partition the mixed-signal design into multiple regions. Some embodiments classify the regions at different time steps of transient analysis. The regions are classified to indicate whether a region is active or inactive at each such time step. Then when analyzing the active regions, some embodiments adaptively apply different solvers to at least two of the active regions based on criteria associated with the active regions. Additionally, some embodiments perform an adaptive bi-direction analysis of the regions.

Abstract: A communication device (100) having a receiver circuit (110), signal processor circuit (120), controller circuit (130), either embodied by integrated circuits or on a single integrated circuit. The transfer of signals between the circuits is timed so as to minimize the effects of noise introduced into any one of the circuits, particularly the receiver circuit (110). The center of a symbol of a received RF symbol is detected and, through hardware control or software control, the transfer of a data signal generated by the signal processor circuit (120), for example, is permitted to occur only during a period(s) of time determined to have minimal effects on the sampling of a symbol in a received signal by the receiver circuit (110).
