ROUTE SEARCH METHOD, TIMING ANALYSIS METHOD, WAVE ANALYSIS METHOD, SIMULATION APPARATUS FOR ELECTRONIC CIRCUIT AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a technology for constant and high-precision performance of a simulation for an operation verification of a designed electronic circuit. SOLUTION: Each route search means 14-16 equipped by a route search apparatus 12 searches routes while distinguishing the routes targeted for a search or selecting one route among more than one route (or combining the routes) with referring to a predetermined condition group, respectively. Accordingly, the number to be extracted is suppressed at a minimum without eliminating any route to be considered. A simulation means 13 performs the simulation for a timing analysis, a pulse width check and the like by using a result of route searches through the means 14-16.
