Structure and generation method of clock distribution network
Abstract:
The present invention provides a structure of a clock distribution network and generation method thereof. The clock distribution network is distributed in multiple local circuit modules. The clock distribution network comprises a clock tree structure and clock mesh structures, wherein the clock tree structure is distributed at least between or among the multiple local circuit modules and has a root node which is a clock access point of the clock distribution network. The clock mesh structures are distributed within at least one local circuit module at least according to a proportion of clock nodes in the local circuit module, a proportion of sequential circuits connected by clock in the local circuit module, a ratio of a total length of clock routing wirings in the local circuit module to a perimeter of the local circuit module, and a proportion of timing violation paths in the local circuit module.
