And a procedure display unit 42 for displaying the above.

Next, the operation of the simulation apparatus 10 according to this embodiment having such a configuration will be described.

The CPU 12 reads out the operation procedure for creating the component inspection simulation program from the ROM 14. This operation procedure is shown in the flowchart of FIG. 3, and after the model selection of the component is performed (STP1), the inspection program corresponding to this selected model is read from the RAM 16 (STP2). further,
External device control data is extracted from the inspection program via the I / O control data storage circuit 18 and the CRT 2
2 is displayed (STP3 and STP4), and various kinds of simulation setting data are created through the simulation condition creating circuit 20 (STP5). After the desired setting data creation work is completed (STP6), these setting data are registered as a simulation program (STP7) and stored in the RAM 16.

The process of creating the setting data will be described in detail below. The process of creating the setting simulation condition is shown in the flowchart of FIG. First, a predetermined external device 28 registered in the inspection program described above.
Is detected (STP101), and the external device 28 used, for example, A / D, D / A, counter, etc., is detected by the CRT 22.
(See STP102 and FIG. 5). Then, the operator touches the touch panel 36 in response to a required display, and the board presence / absence determining circuit 32 causes the desired board 30 to be displayed.
When it is determined that is connected to the I / O controller 26 (YES in STP103), a ten key is displayed on the CRT 22 and a measurement start timer which is a waiting time is input (STP104).

On the other hand, the I / O controller 26 is provided with a substrate 30.
Is not connected (NO in STP103), the unconnected substrate 30 is stored (STP10).
5) The measurement conditions corresponding to the unconnected substrate 30 are detected (STP106). Then, the measurement time and the like in the measurement conditions are set in the timer unit 34 inside the CPU 12 (STP107), and the process proceeds to step STP104.

Next, the process of creating the judgment simulation condition is shown in the flowchart of FIG. First, the judgment item registered in the selected inspection program is detected (STP201), and this judgment item is detected by the CRT2.
2 (see STP202 and FIG. 7). The operator inputs the determination result by touching the touch panel 36 (STP203), and then inputs the determination start time and the determination result output time (STP204).

Further, the process of creating the control timing is shown in the flow chart of FIG. First, the control condition registered in the selected inspection program is detected (STP301), and when this control condition is displayed on the CRT 22 (STP302), it is determined whether or not the desired board 30 is connected ( STP303). If this board 30 is connected (YES in STP303),
“Connected” is stored (STP304). On the other hand, when the substrate 30 is not connected (N in STP303,
O), "no connection" is stored (STP305), and a timer is input according to the control condition (STP306).

Furthermore, the process of creating bar code conditions is shown in the flow chart of FIG. First, the bar code conditions registered in the selected inspection program are detected (STP401), and the CRT 22 displays "Is the bar code actually connected?" (ST
P402). When the operator touches "Y" (YES),
It is stored that "bar code exists" (STP404). On the other hand, if the barcode is not connected, "No connection"
Is stored (STP405), the emulation of "no bar code" is turned on (STP406), and then the processing time of bar code communication is input (STP407).

Further, the process of creating the printing conditions is shown in FIG.
Is shown in the flowchart. First, the printing conditions registered in the selected inspection program are detected (ST
P501), CRT22 displays "Is the printer actually connected?" (STP502). If the operator touches "Y" (YES), "printer is present" is stored (STP504), while if no printer is connected, "no printer" is stored (STP5).
05), the print time is input by a timer (STP506).

Furthermore, the process of creating communication conditions is shown in FIG.
1 is shown in the flowchart. First, when the communication conditions registered in the selected inspection program are detected (STP601), a display for confirming the presence or absence of the communication substrate 30 is displayed on the CRT 22 (STP602). Here, when the operator touches "Yes", it is stored that the board is present (S
When TP604) and “none” are touched, the communication emulation time is input (STP605).

As described above, after the desired setting data is created, the simulation is executed. Therefore, the execution of the measurement simulation will be described with reference to the flowchart of FIG. 12. After the measurement start timer set based on the flowchart of FIG. 4 has elapsed (S
In TP701, YES), and it is determined whether or not the substrate 30 for measurement is connected (STP702). Board 30
If is connected, the measurement process is performed based on a simulation program similar to the actual online inspection program (STP703), and the measured data is stored as determination dummy data (STP70).
4). On the other hand, if the board 30 is not connected, the stored data is output from the timer unit 34 (STP705), and after the timer has elapsed according to the stored data (STP70).
6) and proceeds to step STP704.

In this case, in this embodiment, the operator
The inspection simulation program can be created only by touching the touch panel 36 in accordance with the contents displayed on the CRT 22 according to the operation procedure read from the ROM 14 by the U 12. At that time, control data for external devices is extracted from the inspection program for parts, and setting data for simulation is created based on this control data. , It is possible to create easily and quickly according to the inspection program. Therefore, compared with the conventional method in which the simulation program is created separately from the inspection program, the operation of creating the simulation program can be simplified and made more efficient.

Moreover, since the simulation program is created in accordance with the inspection program, it is not necessary to individually inspect and confirm the inspection program and the simulation program. As a result, there is an effect that the entire program creation work including the creation time of the simulation program and the above-mentioned confirmation work can be easily performed in a short time.

Further, conventionally, the simulation could not be performed unless the board 30 was mounted on the I / O controller 26. However, in the present embodiment, the presence / absence of the substrate 30 is determined by the substrate presence / absence determining circuit 32, and when the substrate 30 is not mounted, the CPU 12
Desired data is stored in the internal timer unit 34. Therefore, there is an advantage that various simulations can be surely performed off-line regardless of the presence or absence of the substrate 30.

The operator has the first option according to the type and specifications of the parts.
It is possible to create an inspection simulation program for a desired component in accordance with the operation procedure read from the storage means. At that time, control data for external devices is extracted from the inspection program for parts, and setting data for simulation is created based on this control data. , It becomes possible to create easily and efficiently according to the inspection program.
Therefore, as compared with the case where the inspection program and the simulation program are individually created, the work of creating the simulation program can be simplified at once.
