The netlist parameters include node parameters of each node of the static netlist. The node parameters include node connection information and execution cycle information. The nodes of the static netlist include nodes of an integrated circuit design from an input to an output. A split node module analyzes, using the netlist parameters, each node in a cycle and determines if each node is a potential split node, which is a node with a projected sub-proof execution time less than a time limit. A split chain module determines if a split chain exists. The split chain includes a connection between potential split nodes from the input to the output at each execution cycle. A reporting module reports nodes of a split chain in response to determining that a split chain exists.

Various implementations provide filtering for pictures. Several such implementations attempt to reduce artifacts caused by over-filtering in a decoding loop. Certain of these implementations provide multiple loop filters, and select a loop filter based on the result of a deblocking filter. One particular implementation applies a first filter to a picture to produce a filtered picture. A second filter is selected based on a difference between a value of a particular pixel in the filtered picture and a value of a corresponding pixel in the picture. The second filter is applied to the particular pixel in the filtered picture.

The invention proposes a fault-tolerant field-oriented control method of five-phase interior permanent-magnet fault-tolerant linear motor (IPM-FTLM) with two nonadjacent short-circuit phase faults. Firstly, the extended Clark transformation matrix can be obtained according to the principle that magnetic motive force (MMF) keeps constant before and after the two-phase open-circuit faults, the constraint that the sum of healthy phase currents is zero and the adjacent two-phase current amplitude is equal. The back electric motive force (EMF) can be estimated by the transposed matrix. The nonlinear strong coupling system becomes the first-order inertia system when using the internal mode controller, the first-order inertia feed-forward voltage compensator and back-EMF observer, as the motor is with fault. Then, according to the principle that the sum of MMF of the healthy phase short-circuit compensation currents and two phases short-circuit fault currents is zero, the short-circuit compensation voltage can be obtained, and then these voltages add vector-controller output voltages, respectively. The invention not only restrains the thrust force fluctuation caused by two nonadjacent short-circuit phase faults, but also more importantly keeps the same dynamic and steady performance as the normal conditions, and also it has the constant switching frequency of voltage source inverter. 1.
