Clock distribution networks are synchronous components in digital circuit design, directly affecting system performance, power consumption, and reliability. Small process with high transistor density in the form of semiconductor technology proceeds to nodes, with effective clock delivery increases. This article examines the trade-offs between H-tree and fishbone clock architectures, analyzing their respective impacts on key performance metrics, including skew, power, and latency. The discussion explores how modern EDA tools employ sophisticated algorithms to select optimal clock distribution strategies based on design parameters such as sink count, floorplan geometry, and operating frequency. Integration challenges with other physical design elements are addressed, including macro blockage avoidance, power mesh interaction, and non-default routing rule application. Through a detailed comparison of architectural characteristics and performance effects, the article provides insight into the effective clock-synthesis scheme for modern semiconductor designs.
