Abstract

According to an example embodiment of the invention, a hotspot detection method and device for a circuit layout and a computer readable storage medium are provided. The hotspot detection method for the circuit layout comprises the following steps: generating a plurality of sub-jobs for detecting hotspots with potential defects from the circuit layout; each sub-job corresponds to one layout unit ofthe circuit layout and specifies one or more operations to be performed with the layout unit. The method also includes the steps: allocating the plurality of sub-jobs to the plurality of processing devices based on the configuration information of the plurality of processing devices and the type of one or more operations. At least one processing device of the plurality of processing devices is configured with an accelerated processing resource. The method further includes the step of determining one or more hotspots included in the circuit layout based on detection results of the plurality ofsub-jobs by the plurality of processing devices. In this way, a rapid and efficient hotspot detection scheme can be advantageously implemented.

Description

technical field [0001] Embodiments of the present disclosure generally relate to integrated circuits, and more particularly, to a hotspot detection method, apparatus, and computer-readable storage medium for circuit layout. Background technique [0002] The circuit layout (also referred to as the layout for short) is a series of geometric figures transformed from the design and simulation of the optimized circuit, which contains the physical information data related to the device such as the size of the integrated circuit and the topology definition of each layer. IC manufacturers make masks from this data. The layout pattern on the mask determines the size of the device or connection physical layer on the chip. [0003] As the technology node of the integrated circuit manufacturing process decreases, the distance between target patterns in the integrated circuit decreases, and the density of layout patterns corresponding to the target patterns on the mask increases. Some ...
