Abstract
A user device receives a request to perform an automatic clock insertion operation for an integrated circuit; retrieves location information regarding a group of components, of the integrated circuit, that use a clock signal; deploys a clock mesh based on the location information regarding the group of components; and inserts drop points into the clock mesh; deploys a particular buffer for a particular drop point; maps a component, of the group of components, to the particular buffer; generates a clock box for the particular buffer, where dimensions of the clock box are based on a location of the component; deploys an H-tree for the clock box, where dimensions of the H-tree are proportional to the clock box dimensions; connects the H-tree to the component; and displays or stores clock mesh information, information regarding the group of buffers, information regarding the H-tree, and the location information regarding the group of components.
