Abstract
A power domain is automatically generated. A computer performs a function simulation process 9 for evaluating whether or not a designed circuit satisfies a specification, and a clustering process 10 which obtains a power domain by clustering logical blocks in which activation timings are within a range, based on the result of the function simulation process. Since the power domain is obtained by a process performed by the computer, the power domain can be optimized compared to a case when it is obtained by hand (manual work of the designer).
Claims7
A layout method of a semiconductor integrated circuit using a computer, comprising a function simulation process for evaluating whether or not a designed circuit satisfies a specification, and a clustering process which obtains a power domain by clustering respective logical blocks in which activation timings are within a range, based on a result of the function simulation process, the both processes being performed by the computer.
A program causing a computer to execute a function simulation process for evaluating whether or not a designed circuit satisfies a specification, and a clustering process which obtains a power domain by clustering logical blocks in which activation timings are within a range, based on a result of the function simulation process.
