Abstract

PURPOSE:To easily and speedily simulate a designed circuit by displaying elements together with data which are required for the simulation and changing the display state of the elements according to the values of the data. CONSTITUTION:The classifications of the delay values of the respective elements and display conditions regarding display colors by the classifications are set in a display format setting part 5. A display format control part 6 reads the conditions and also reads delay values of the respective elements of the circuit out of a data storage part 3 at the same time, and then passes the set display conditions and the delay values to a display control part. The display control part 2 which have received the data displays a circuit diagram and the delay values of the elements, element by element, at a display part 1 with information from a circuit coordinate information part 4 and changes the display colors of the displayed elements according to the classifications of the set delay values. Consequently, the circuit diagram to be simulated is displayed at the display part 1 so that the necessary delay values are displayed by the elements and the display colors are made different according to the numerals of the delay values.

2. Description of the Related Art FIG. 3 is a block diagram showing a configuration of a conventional circuit display device. In FIG. 3, 1a is a circuit display unit for displaying a circuit diagram, 2a is a circuit diagram display control unit for displaying a circuit diagram on the circuit diagram display unit 3, and 3 is a data storage unit for storing data necessary for circuit simulation. 10 is a character display unit for displaying character data, 11 is a circuit diagram control unit 2
It is a central control unit for controlling a and displaying character data on the character display unit 10 using the data in the data storage unit 3 as a database.

When simulating the designed circuit, the character display section 10 displays data required for the simulation, and the data displayed on the circuit display section 1a corresponds to each element of the circuit to be simulated. The data displayed is searched, and the circuit displayed on the circuit display unit 1a is simulated using the data.

[0004]

Since the conventional circuit display device is configured as described above, when the designed circuit is simulated, the data necessary for the simulation is stored in a file, a database, etc. containing the data. Referring to, the data corresponding to the element of the circuit is selected from the state (character display unit 10) displayed as a character string in a place different from the place where the circuit diagram is displayed (circuit display unit 1a). There was a problem that it had to be searched and it was very troublesome.

The present invention has been made in order to solve the above-mentioned problems, and the data for simulation of a designed circuit is displayed corresponding to each element of the circuit, and the designed circuit is displayed. The objective is to enable simple and quick simulation of.

[0006]

The circuit display device of the present invention stores data for storing data for simulation, and position information of the position of each element of the circuit and the corresponding data. Circuit diagram coordinate information storage means, display format setting means for setting the display state of each element of the circuit, and data stored in the data storage means in the display state set by the display format setting means. And a display control means for controlling to simultaneously display a circuit and data corresponding to each element of the circuit.

[0007]

In the displayed circuit, each element is displayed together with the data necessary for the simulation, and the display state of the displayed element changes depending on the value of the data.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a circuit display device according to one embodiment of the present invention. In FIG. 1, 1 is a display unit that displays a designed circuit diagram, 2 is a display control unit that controls the display unit 1, 3 is a data storage unit that stores delay values that are data required for simulation, and 4 is a A circuit diagram coordinate information section 5 for storing position information of each element and a delay value corresponding to the element for displaying on the display section 1 is a display format of each element on the display section 1 depending on the range of the delay value. Is a display format setting unit, and 6 is a display format control unit that controls the display color of the element according to the display format set by the display format setting unit 5 and the display of the delay value.

FIG. 2 is a screen view showing the display unit 1 of the circuit display device of FIG. In FIG. 2, 7 is a condition display section showing the display colors of the elements set in the display condition setting section 5 and their divisions, 8 is a display of delay values which are element data for simulation, and 9 is a display color. A strange element is shown. In this circuit display device, first, the display condition setting unit 5 sets the display conditions of the delay value of each element and the display color for each of the sections. Next, the display format control unit 6 reads the condition, simultaneously reads the delay value of each element of the circuit from the data storage unit 3, and passes the set display condition and the delay value to the display control unit 2.

The display control section 2 to which the data is passed displays the circuit diagram and the delay value of each element on the display section 1 based on the information from the circuit coordinate information section 4, and the set delay value is set. The display color of the element to be displayed is changed according to the category. As a result of the above, the circuit diagram to be simulated is displayed on the display unit 1 with the delay values necessary for the simulation being attached beside each corresponding element, and
Depending on the set condition (displayed on the condition display unit 7), the display color of the element is changed and displayed according to the value of the delay value. For example, in FIG. 2, the element 8 having a different display color has a delay value of 1.1, and is therefore displayed in the display color of 1.0 to 2.0 shown in the condition display section 7.

Although the display color of the element is changed in the above embodiment, the thickness of the line or the line type such as the solid line and the broken line may be changed instead of the display color. The same effect can be obtained by changing the display color of the signal line, the thickness of the line, and the line type instead of the element. Further, although the circuit display device has been described in the above embodiments, the above functions may be realized by software in a CAD system such as a large computer, a workstation, a personal computer.

[0012]

As described above, according to the present invention, data necessary for simulation is displayed in the vicinity of the element of the displayed circuit diagram, and the display state of the element is changed according to the size of the data. Therefore, there is an effect that data of each element for simulation can be easily obtained, and a designed circuit can be easily and quickly simulated.
