摘要: A system includes a non-transitory computer readable medium configured to store instructions thereon. The system further includes a processor connected to the non-transitory computer readable medium. The processor is configured to execute the instruction for comparing a size of a via pillar structure of a first layout pattern of a plurality of layout patterns with a size of a via pillar structure of a second layout pattern of the plurality of layout patterns, wherein each of the plurality of layout patterns meets an electromigration (EM) rule. The processor is further configured to execute the instructions for replacing, in a layout design, the first layout pattern with the second layout pattern in response to the size of the via pillar structure of the second layout pattern being less than the size of the via pillar structure of the first layout pattern.

摘要: An integrated circuit design method includes receiving an integrated circuit design, and determining a floor plan for the integrated circuit design. The floor plan includes an arrangement of a plurality of functional cells and a plurality of tap cells. Potential latchup locations in the floor plan are determined, and the arrangement of at least one of the functional cells or the tap cells is modified based on the determined potential latchup locations.

摘要: A method performed by at least one processor includes: accessing a layout of an integrated circuit (IC), where the layout comprises a first cell coupled to a metallization unit and the metallization unit includes one of a first via pillar (VP) structure and a single-via stacking structure; determining whether the layout meets a timing constraint; and performing, in response to the layout being determined as failing the timing constraint, an engineering change order (ECO) operation by replacing the metallization unit with a second VP structure.

摘要: In examples described herein, methods for via pillar placement and an integrated circuit design including a via pillar are described. In some instances, a path within an integrated circuit or proposed integrated circuit design can be identified as having negative slack. In such instances, in particular where the path includes a fanout to input pins of receivers, a via pillar can be inserted at a location prior to fanout of the path. The via pillar can be inserted, for example, proximate to the fanout, but between the fanout and an output pin of a driver that is connected to the path.
