摘要： PURPOSE:To prevent a malfunction, etc., from being overlooked, by executing a monitoring designation to an element which desires to monitor a variation of an output signal, executing a simulation, and outputting an alarm message, when a variation has been generated in a designated signal. CONSTITUTION:A test data 112 gives a procedure, a condition and an instruction of a test which is executed to a model data 111, and at every test item, an observing instruction of an input test pattern and an output pattern is executed. A monitor designating data 113 executes an instruction to an element which does not derive a signal value, but desires to monitor only a signal variation point. An output pattern 141 is a result of a signal value of the element which has been brought to an observing instruction at the time when a simulation has been executed to the model data 111 by the input test pattern of the test data 112. Also, an alarm message 142 is outputted, when a variation of a signal has been generated in the element which has been instructed by the monitor designating data 113, when the simulation is being performed in the same way.

摘要： PURPOSE:To obtain a method of building a diagnosing algorithm which enables highly accurate diagnosis of various objects to be diagnosed. CONSTITUTION:In a method of building a diagnosis algorithm, values pertaining to a plurality of parameters for diagnosis are measured for a group of objects to be diagnosed divided into those normal and abnormal in character and measured values about parameters for diagnosis undergoes a statistical processing. The plurality of parameters for diagnosis predected to be effective parameters are extracted from the group of parameters for diagnosis based on the processing results and a diagnosis level is determined to judge the propriety of the characters of he objects to be diagnosed based on measured values about the effective parameters for diagnosis extracted. This enable highly accurate diagnosis for various objects to be diagnosed thereby making it possible to build highly reliable diagnosis algorithm for the various objects to be diagnosed.

摘要： PURPOSE:To generate a test program for the whole of a printed board efficiently and precisely by expanding an IC to a gate level in addition to printed board network information. CONSTITUTION:A test program editing processing part 741 inputs printed board network information 721, a library 722, and IC network information 723 to generate, edit, and output the test program 727 for the whole of the printed board. A test execution processing part 744 tests the printed board 610 to be tested according to the program 727. Then, when the test pattern of an IC is not registered in the IC library 722, the information 721 and information 723 are inputted in a step 260 to generate a deficient test pattern, which is registered in the library 722. Thus, the deficient test pattern is generated in the step 260 and registered in the library 722, so test patterns of all ICs are extracted from the library 722 in a step 720 without any omission.

摘要： PURPOSE:To execute a correct simulation and to execute easily the simulation of a product even when the feed-back is included in a multiple way by hoisting an individual flag to the element in which events propagate at every initial event. CONSTITUTION:A graphic input system 50 developed for inputting a design result inspecting device 100 is used, and the system 50 is composed of a large- sized computer 51, an input device 52, a graphic display 53, a disk 54 and a program 55 for processing the graphic. The graphic data preserved at the disk 54 are inputted to the large-sized computer 101 of the device 100 when the design result is inspected, and a program group 150 having a simulation model forming program 151, a simulation executing program 152, etc., is connected to the computer 101. An individual flag is hoisted to the element which the event propagates at every initial event, and even when the feed-back is included in the multiple way, the correct simulation can be executed.

摘要： PURPOSE:To check a control board efficiently and reduce the trouble of check by using a model to check design result of a controller and obtaining the history of input/output signals as a test pattern and checking the control board after production on a basis of this pattern. CONSTITUTION:A design result checking device 300 of a checking device 20 generates models of the control board and a controller object, which are designed before production of the control board, by software and accesses models in accordance with test procedures to obtain various responses. Further, the test pattern is extracted and is stored in a disc memory 500. A control board checking device 400 extracts the history of input/output signals of a control board 600 to be checked after production. An input signal is given to the control board 600 as a test input pattern, and it is checked whether the response coincides with a test output pattern, namely, an output signal or not. Thereafter, it is checked whether the control board is produced correctly or not on a basis of check results.

摘要： PURPOSE:To substantially reduce the number of elements selectively operated and to reduce the simulation time by automatically setting initial condition only for the element group which relates to the element of which output results are required. CONSTITUTION:A control panel monitoring device 20 is composed of design results a monitoring device 100 and a products monitoring device 200 and also an M/T 300 which connects these two devices. Also a pattern input system 50 of the device 100 consists of a mainframe computer 51, an input device 52, and a graphic display 53. Since it is possible to automatically set the initial condition only for the element group which relates to the element whose output results are required to be monitored, the object of simulation can be limited. Namely, operation at each time is necessary while establishment of initial value is only one time, therefore processing time will be reduced by limiting the object of operation. Thus, the number of elements to be selectively processed will be reduced and simulation time will be substantially shortened.
