Patent/Application # US 7,856,347
Simulation of models wihtin a distributed environment is facilitated. A model is partitioned based on clock domains and communication between partitions on different processors is performed on synchronous clock boundaries. Further, data is exchanged across the network on latch boundaries. Thus management aspects of the simulation, such as management asssociated with the global simulation time, are simplified.
Title Symphony: A Simulation Backplane for Parallel Mixed-Mode CO-Simulation of WLSI Systems
An integrated simulation paradigm in which parallel mixed-mode co-simulation is accomplished by integrating sequential simulators in a software simulation backplane.
Patent/Application # US 2010/0332202
Parallel simulation of general time-domain circuits that are represented by non-linear/linear differential algebraic equations is accomplished by partitioning them into smaller subcircuits via a novel combination of the companion form representation of the given circuit and efficient node splitting, during Newton Raphson iterations, at any time point.
Title Flowmaster Announcements
Flowmaster is a product which accommodates parallel co-simulation and has been available for many years. The uploaded document is just one example of a Flowmaster solution from 2008. The URL links to Flowmaster's history of product announcements on their web site - sifting through the announcements shows the co-simulation was known more than 1 year prior to the instant priority date.
