Latest Patents
Among his latest patents, Qian Cai has developed methods for synchronized transient-envelope and event-driven simulation of electronic circuits. In one embodiment of this invention, a method is disclosed that includes simulating an analog component of a circuit over a first simulation time period with a first envelope simulation. The method adaptively switches from simulating the analog component with the first envelope simulation to a transient simulation over a second simulation time period. This adaptive switching occurs in response to the envelope simulation accuracy falling below a predetermined level or when expected digital transitions may occur.
Another significant patent is the synchronized envelope and transient simulation of circuits. This method involves partitioning a circuit into multiple blocks, performing simulations of different types for radio-frequency and non-radio-frequency blocks, and synchronizing these simulations at specific time steps to generate output waveforms for the entire circuit.
