Circuit analysis device allowing more accurate analysis of signal propagation delay in circuit representation of a highly abstract level

摘要

The present invention provides a circuit analysis device including: storage unit having stored therein: connection information about multiple components; delay information including information about the delay time of a discrete component and a chain delay time which is a delay time in the case in which a chain delay effect is generated by a connection with another component about each kind of the multiple components; and chain effect propagating component information including information about kinds of chain effect propagating components which are components for transmitting the chain delay effect, and data processing unit for: referring to the information stored in the storage unit; performing a total delay time calculation process of sequentially adding the delay times of the components along a signal path in the circuit; and if the chain effect propagating component is halfway through the signal path in the total delay time calculation process, examining a connection relation between components that precede and follow the chain effect propagating component and determining a delay time of the component that follows the chain effect propagating component that corresponds to the connection relations.
