  • Patent number: 10963618
    Abstract: Electronic design automation systems, methods, and media are presented for multi-dimension clock gate design in clock tree synthesis. In one embodiment, an input list of clock gate types is accessed, and the list is then used in generating a clock gate matrix. A circuit design with a clock tree is then accessed. The multi-dimensional design involves automatically selecting, for a first clock gate of the routing tree, a first clock gate type from the clock gate matrix based on a size and associated area for the first clock gate type to select a drive strength value for the first clock gate in the routing tree. The first clock gate is then resized to generate a resized first clock gate using the clock gate matrix to adjust a first delay value associated with the first clock gate while maintaining the drive strength value.

  • Patent number: 10963617
    Abstract: Aspects of the present disclosure address systems and methods for fixing clock tree design constraint violations. An initial clock tree is generated. The generating of the initial clock tree comprises routing a clock net using an initial value for a parameter that controls a priority ratio between total route length and a maximum source-to-sink route length in each net of the clock tree. A violation to a clock tree design constraint is detected in the clock net in the clock tree, and based on detecting the violation, a rerouting candidate is generated by rerouting the clock net using an adjusted value for the parameter. A target clock tree is selected based on a comparison of timing characteristics of the rerouting candidate with the clock tree design constraint.
