Simulation analysis device and simulation analysis manner

摘要

PROBLEM TO BE SOLVED: To provide a simulation analyzing device which facilitates the specification of an analytic node for investigating cause, easily generates a circuit diagram of an analytic path, and shortens a verification time. ;SOLUTION: When the node at the start point of an analysis is specified, a 1st retrieval device 13 retrieves an element including the node for output and the input node of the element. Then a waveform display device 14 displays the waveform of signal information at the retrieved node by retrieving the signal information from a 1st data base 19. At the same time, a circuit display device 16 generates and displays the circuit from the start point of the analysis to the retrieved element. A selecting device 17 selects a node in a coming analytic route from display devices 14 and 16. Nodes except the selected node are deleted from the display devices 14 and 16 and the stage right before the selected node is retrieved and passed to the display devices 14 and 16 under the control of a controller 18.;COPYRIGHT: (C)1999,JPO
