Configuration information including number of normal cell areas and number of spare cell areas arranged in a memory macro and a size of each cell area is extracted from circuit design information, and electrical test results of the normal cell areas and the spare cell areas arranged in the memory macro are collected. Arrangement information corresponding to a collection order of the electrical test results is converted to a two-dimensional coordinate value for two-dimensionally displaying the arrangement information corresponding to a collection order of the electrical test results in a unit of cell area in association with a physical layout of a memory cell in the memory macro based on the configuration information. The collected electrical test results are displayed based on the two-dimensional coordinate value so that the normal cell areas and the spare cell areas can be distinguished.

A scheme for controlling a screen display capable of allowing the addition of new functions such as the note entry and the pointing according to the input events not requested by the application program, and preserving the meaning attributed to the drawings related to the windows even when the window state change is made. The screen display is controlled by transmitting the inputs entered at the input device as input events to an application program, and supplying the display requests made by the application program according to prescribed types of the input events as well as the display requests according to the input events other than the prescribed types to the output device. Also, when the display of the window data is changed, the display of the drawing data is also changed in accordance with a change made in the display of the window data. Drawing data superposes or overlays separate window data.

A scheme for supporting cooperative works capable of reproducing the contents of the past works from the recorded history of the cooperative works accurately, such that the cooperative works can be carried out efficiently and smoothly. In this scheme, the inputs made by each user during the cooperative works are stored in correspondence to input target data indicating input target applications of the inputs as a record of the cooperative works. Then, afterwards, the input target applications indicated by the input target data are re-executed according to the stored inputs to reproduce results of the cooperative works resulting from the inputs which can be presented to each user.

A scheme for controlling a screen display capable of allowing the addition of new functions such as the note entry and pointing according to the input events not requested by the application program, and preserving the meaning attributed to the drawings related to the windows even when the window state change is made. The screen display is controlled by transmitting the inputs entered at the input device as input events to an application program, and supplying the display requests made by the application program according to the prescribed types of the input events as well as the display requests according to the input events other than the prescribed types to the output device. Input events are transmitted to a window server program and then transmitted to a communication relay program which handles input events and output requests from the application program to the window server. Also, when the display of the window data is changed, the display of the drawing data is also changed in accordance with a change made in the display of the window data.
