Abstract

PURPOSE:To improve the efficiency of input operation by providing plural time bases on an input picture displayed on a display device and widening the time length of the input of expected value data. CONSTITUTION:An expected value storage part 22 processes an expected value which is inputted on a keyboard 25 or with a mouse 26 by the expected value processing part 23 and stores the result. An expected value display part 24 converts the expected value which is inputted numerically into a waveform by the expected value processing part 23 and displays it. The time bases are provided on the input picture displayed on the expected value display part 24 and the input time length of the expected value data can be widened. Thus, the expected value in a wide time zone can be inputted and the efficiency of the input operation can be improved.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention... The present invention relates to a method for inputting an expected value to automatically compare and match the output result of a logic simulator used for verifying the design of a logic circuit such as an LSI with a predicted expected value.

[Conventional technology]

Conventionally, as a method of inputting expected values for comparison and comparison with the output results of a logic simulator used for verifying logic circuit g designs, one time axis 1 is displayed on the screen of a display device as shown in Figure 5. is displayed, and for multiple signals 2,
I had entered an expected value of 3. [Problems to be Solved by the Invention] In the above conventional technology, the time range that can be input is narrow, and in order to input the expected value to the end for a certain signal, it is necessary to move the screen many times, and each time, Since the screen is recreated and displayed, there is a waiting time for input, and if you want to see the previous input result, you have to move the screen to see it, which makes it difficult to input smoothly. Ta. An object of the present invention is to provide multiple lines of time axes, expand the input time range, and reduce screen movements in order to reduce the number of screen movements and realize efficient input. [Means for Solving the Problems] In order to achieve the above object, the present invention provides 20 lines of time axes on the display screen of a display device for inputting expected values, expands the input time range, and This reduces the number of movements to 1720. [Operation] In the present invention, a plurality of lines (two lines) are displayed on the screen of a display device.
The time axis (line 0) is displayed, and input the expected value of the signal expected as the output according to the displayed time axis.
Since there are multiple time axes, it is possible to enter expected values for a wide range of time periods. [Examples] Examples of the present invention will be described below with reference to the drawings. Figure 1 is a configuration diagram showing an embodiment of the present invention. This embodiment is an embodiment in a workstation 21, and 22 is an expected value storage unit, and the expected value inputted by the keyboard 25 or the mouse 26 is stored in the expected value processing unit 23.
It is processed and stored by . Reference numeral 24 denotes an expected value display section, in which the expected value input as a numerical value is converted into a waveform by the expected value processing section 23 and displayed. Figure 2 shows the input/display processing flow in this embodiment. Step 31 is a process of displaying 20 lines on the time axis as an input screen for inputting expected values, and step 32 is a process of displaying 20 lines on the time axis as an input screen for inputting expected values.
5 (Fig. 1) or the mouse 26 (Fig. 1). Step 33 is the process of reading the signal name, expected value, etc. input using the mouse 26 (Fig. This is a conversion process, and step 34 is a process of displaying the created waveform data as a waveform on the expected value display section 24 (FIG. 1). Figure 3 shows the expected value display section 2.
4 (Fig. 1) is an example displayed on the display device, and 41 is an example of an input display when inputting the expected value manually, and the expected value is input as a numerical value. 42 is an example in which the input expected value is converted into a waveform and displayed. [Effects of the Invention] According to the present invention, as a method for inputting expected values to be compared with logical simulation results, since the time axis is displayed in multiple lines, it is possible to input expected values in a wide range of time periods without frequently moving the screen. Values can be entered, improving the efficiency of input work.
