  • Publication number: 20190148290
    Abstract: Exemplary embodiments for various via pillar structures include one or more first conductors in a first interconnect layer of a semiconductor stack interconnected with one or more second conductors in a second interconnect layer of the semiconductor stack. The one or more first conductors and/or the one or more second conductors within the first interconnect layer and the second interconnect layer, respectively, can traverse multiple directions. In some situations, this allows multiple interconnections to be utilized to interconnect the one or more first conductors and the one or more second conductors. These multiple interconnections can reduce resistance between the one or more first conductors and the one or more second conductors thereby improving performance of signals flowing between the one or more first conductors and the one or more second conductors.

  • Patent number: 10289797
    Abstract: Aspects of the present disclosure address improved systems and methods for local cluster refinement during clock tree synthesis for integrated circuit designs. In accordance with some embodiments, the methods for local cluster refinement may include pin move refinement and local reclustering. With pin move refinement, pins are moved from clusters that fail to satisfy design rule constraints to nearby clusters that satisfy design rule constraints. With local reclustering, groups of neighboring clusters that fail or nearly fail to satisfy design rule constraints are dissolved and corresponding pins are regrouped to form new clusters that satisfy design rule constraints.

  • Patent number: 10216880
    Abstract: Methods and systems of optimization of and Integrated Circuit (IC) design disclosed herein result in a power efficient clustering of circuit devices. The methods may depart from the conventional geometric clustering using a nearest neighbor approach when wiring flops to local clock buffers. To reduce the number of clock-gaters, the methods in one embodiment use a grouping of flops wired to a common clock-gater to form nodes, which are then wired to the local clock buffers based on a load-balancing process. In another embodiment, the methods use a local cleanup process to rewire the nodes between neighboring clock buffers to further reduce the amount of clock-gaters.

  • Publication number: 20190027088
    Abstract: A display is provided. The display includes a display panel and a timing controller. The timing controller controls the images displayed on the display panel according to a display driving signal from a host and the display driving configuration of the display panel. The timing controller determines whether there is an error in the display driving signal, and calculates an error count. The timing controller determines whether the error count is lower than a predetermined threshold. If so, the timing controller controls the display panel to display the display images normally according to the display driving signal. If not, the timing controller reports a display error signal to the host, so that the host dynamically updates the display driving configuration.
