Abstract
A logic simulation method includes causing a physical specification detector to detect physical specifications of an analog circuit (a PLL circuit and a DLL circuit) as a verification object described in a logic library; causing a monitor to monitor whether a signal or setting during a logic simulation satisfies the physical specifications; and causing a warning section to issue a warning when the signal or the setting fails to satisfy the physical specifications.
