Abstract
A method and program for designing an electronic circuit, especially a clock tree and a sub-clock tree, within a set of sinks with given target arrival time windows, preferably on an integrated circuit. The clock tree and the sub-clock tree are preferably connected through one or multiple fixed circuits which must not be altered, cloned or removed. Several alternative implementations of the at least one logic structure are built and for each of the several alternative implementations data is stored. A set of configurations is built, each configuration comprising a combination of the one or several alternative implementations and each configuration satisfying the target arrival time windows at the complete set of sinks. A configuration is selected according to an evaluation of the data, preferably latency data, for constructing the configuration. No manual interaction is needed and a configuration with minimum latencies is provided.
