Abstract: A range-pattern-matching-type DRC-based process hotspot detection is provided that considers edge tolerances and incomplete specification (“don't care”) regions in foundry-provided hotspot patterns. First, all possible topological patterns are enumerated for the foundry-provided hotspot pattern. Next, critical topological features are extracted from each pattern topology and converted to critical design rules using Modified Transitive Closure Graphs (MTCGs). Third, the extracted critical design rules are arranged in an order that facilitates searching space reduction techniques, and then the DRC process is sequentially repeated on a user's entire layout pattern for each critical design rule in a first group, then searching space reduction is performed to generate a reduced layout pattern, and then DRC process is performed for all remaining critical design rules using the reduced layout pattern.

The system also creates a plurality of kernels configured to identify hotspots, where each kernel is constructed using the extracted critical features of the non-hotspot clusters and the extracted critical features from one of the hotspot clusters, and each kernel is configured to identify hotspot topologies different from hotspot topologies that the other kernels are configured to identify.

Abstract: An ECO hold time fixing method fulfills a short path padding in a placed and routed design by a minimum capacitance insertion. In the method, a padding value determination step receives the placed and routed design and is based on a cell library, timing constraints, and a timing analysis report to determine padding values and locations required for each gate of the placed and routed design to output. A load/buffer allocation step is based on a spare cell information, a dummy metal information, and the padding values and locations to achieve the short path padding in the placed and routed design.

Abstract: An accurate process hotspot detection technique based on DRC is provided. In this technique, critical DRC rules can be extracted from a pattern. This extraction can include generating horizontal tiles and vertical tiles in the pattern, and adding directed edges to indicate relations between adjacent tiles in the pattern. Rule rectangles, which can also be generated during the critical DRC rule extraction, describe polygon placement in the pattern with a minimal number of critical DRC rules. The extracted DRC rules can be included in a DRC runset file. DRC can be performed with the DRC runset file on a layout. The DRC results can be filtered using the rule rectangles to identify potential hotspots and to verify actual hotspots.

An initial feasible topology is found. A flow network is created based on the initial topology. Negative cycles are iteratively checked and removed until no more negative cycles.

Abstract: A method for analog placement and global routing considering wiring symmetry performs a layout for a circuit which is described by a netlist having a set of devices and wires. First, the method inputs the netlist, and each device thereof has a design constraint and a corresponding priority. Based on the priorities, it performs a sorting on the devices to establish a constraint library. Then, based on the design constraint and corresponding priority of each device, the method establishes a hierarchical constraint tree. According to the hierarchical constraint tree, the method performs placement of each device, wherein possible shape of each device is represented by a shape curve. For each placement of the device, the method calculates a corresponding cost function. Then, it selects an optimum placement of the device according to the cost functions. The method establishes an RSMT for each wire and then performs an analog routing.

Abstract: A method for enhancing text image is applicable to a digital image containing monochrome text. The method is first to label text pixels and to-be-determined pixels according to grayscales of the image pixels. Then, to identify some mostly-be text pixels, smooth them into text pixels; and look for text edge pixels from the rest of the to-be-determined pixels, and fill the text pixels to enhance contrast of text and background. The zigzags are thus removed and the text clearness is improved.
