Patent number: 10467059Abstract: A method for determining timing constraints in dataflow models is disclosed. The method includes receiving node information specifying a plurality of dataflow nodes, as well as coupling between various ones of the dataflow nodes. The method further comprising receiving timing information specifying timing constraints for at least some of the dataflow nodes. Based on the node information, the couplings between the nodes, and the timing information, a timeline dependency graph (TDG). The timeline dependency graph illustrates a timeline, mappings between nodes with side effects to firing times of those nodes on the timeline, and dependencies between nodes.Type: GrantFiled: March 28, 2017Date of Patent: November 5, 2019Assignee: National Instruments CorporationInventors: Patricia Derler, Kaushik Ravindran, Hugo A.

Patent number: 7296246Abstract: The present invention provides a process for constrained clock skew scheduling which computes for a given number of clocking domains the optimal phase shifts for the domains and the assignment of the individual registers to the domains. For the within domain latency values, the algorithm can assume a zero-skew clock delivery or apply a user-provided upper bound. Experiments have demonstrated that a constrained clock skew schedule using a few clocking domains combined with small within-domain latency can reliably implement the full sequential optimization potential to date only possible with an unconstrained clock schedule.Type: GrantFiled: November 5, 2003Date of Patent: November 13, 2007Assignee: Cadence Design Systems, Inc.Inventors: Andreas Kuehlmann, Kaushik Ravindran, Ellen Sentovich
