Abstract

The invention discloses an editing method supporting independent revocation and independent reworking on each design, and is used in the field of EDA design. When a large amount of design is opened at the same time, different windows have independent operating records. By means of the editing method, independent revocation and independent reworking can be carried out according to contents of the currently-edited windows, and the effect that what you see is what you get is achieved.

Description

A kind of support independently cancelled and the edit methods of reforming each design

Technical field

Cancelling (Undo) is edit methods basic in eda tool with (Redo) operation of reforming.The invention belongs to eda tool design field.

Background technology

In eda tool, user will operate frequently, carries out much orders, and some amendment may be also improper sometimes, at this time needs the amendment before cancelling, and this just needs destruction operation.And if find after cancelling design or bad to need redo operation.Cancelling with reforming is two very basic orders in eda tool.

In IC design, because circuit is hierarchy type design, therefore user tends to open multiple designs after starting an eda tool simultaneously.Each design needs to modify, and this amendment conventionally all interts and carries out.Such as after design A is modified, current editor has been switched to design B, now again B is revised.Then again current editor is switched to A.If now see that the amendment in A is improper, user need to carry out destruction operation so.First traditional destruction operation is to cancel nearest operation, because nearest operation is carried out B, therefore the amendment of B is cancelled, but current that see is A, want the effect that reaches desired, need to carry out repeatedly destruction operation, also brought less desirable effect simultaneously, the amendment of B has also all been cancelled, and at this time because B window is because be not current editor, user may can't see the impact of the generation of this behavior at all.Redo operation is also the same effect.That is to say that this to cancel with reforming be that all amendments are carried out for the overall situation.

Summary of the invention

The present invention proposes cancelling and rework method of a kind of What You See Is What You Get.Cancel with redo operation all for the content of current editor, and the overall situation not.That is to say, after design A is modified, current editor has been switched to design B, now again B is revised.Then again current editor is switched to A.If now see that the amendment in A is improper, user carries out destruction operation so, and in A, nearest amendment is cancelled, and amendment in B remains unchanged.Redo operation is also the same effect.

Brief description of the drawings

Fig. 1 opens two design A and B

Fig. 2 creates a rectangle in design A

Fig. 3 creates a rectangle in design B

Fig. 4 carries out destruction operation in design A

Fig. 5 carries out destruction operation in design B

Fig. 6 carries out redo operation in design A

Fig. 7 carries out redo operation in design B

Concrete implementation step:

In conjunction with a practical operation, with explanation implementation step, operating process step is as follows:

1) open two design A and B.

2) A is set to current editor, and A is made an amendment, for example, create a rectangular object;

3) B is set to current editor, and B is made an amendment, for example, create a rectangular object;

4) A is set to current editor, carries out destruction operation, the rectangle being now just created in A disappears;

5) B is set to current editor, carries out destruction operation, the rectangle being now just created in B disappears;

6) A is set to current editor, carries out redo operation, now the rectangle in A reappears;

7) B is set to current editor, carries out redo operation, now the rectangle in B reappears.

Claims

1. in an electronic design automation software, under multiwindow edit pattern, can independently cancel and the edit methods of reforming each design.Its feature is as follows:

(1), while carrying out destruction operation, only cancel the amendment of carrying out last time in current editor;

(2), while carrying out redo operation, what carried out the last time of only reforming in current editor cancels;

2. the claimed combination with feature 1,2;
