Abstract
The invention discloses a layout dividing device which can be applied to the designing of an IC layout so as to solve the problems that the layout can not be divided or the division causes damage to graphs and devices in the layout. The layout dividing device carries out identification on the graphs and the devices in the layout at dividing boundaries, and forms indivisible signs on the graphs or the devices on dividing lines so as to avoid damage during division; and the divided layout can also be reintegrated as required, thereby making up for the deficiency of the traditional layout dividing technology.
Description
Technical field
The present invention relates to a kind of integrated circuit diagram designing technique.
Background technology
Along with the continuous expansion of IC design scale, the area of domain constantly increases, and we usually hope and can cut apart domain, reduce the domain scale.The invention provides a kind of device of cutting apart domain; Can a bigger domain be divided into some; Aspect a lot of, can greatly improve layout design efficient; Work such as layout design rules inspection and reparation just can realize that many people repair simultaneously through this method, and the domain after the reparation can synthesize again.
Summary of the invention
The technical matters that the present invention will solve provides a kind of device of cutting apart domain, can be divided into some to domain.
For solving the problems of the technologies described above, the device of cutting apart domain of the present invention adopts following technical scheme to realize that this device comprises figure decision means, device decision means and domain partition member.When domain is cut apart; At first use figure decision means and device decision means; Figure and device to being on the cut-off rule are judged, the figure and the device that are on the cut-off rule are done indivisible sign, avoid cutting apart figure and device are brought destruction; To being in figure and the device within the cut zone fully, figure decision means and device decision means can be made divisible sign.Next do dividing processing by the domain partition member, produce the domain make new advances, shielded figure and device are also placed in together on the cut-off rule being in simultaneously, produce a shielded public domain.
Adopt the device of cutting apart domain of the present invention; It can shield to figure or the device that is on the cut-off rule; Avoid domain is produced destruction; When the needs domain is synthetic again, can also be synthetic again all domains that split, for layout design in many aspects parallel processing great facility is provided.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation:
Fig. 1 is a domain segmenting device structural drawing.
Fig. 2 is a figure decision means structural drawing.
Fig. 3 is a device decision means structural drawing.
Fig. 4 is a domain partition member structural drawing.
Embodiment
As shown in Figure 1, the device of cutting apart domain of the present invention comprises figure decision means, device decision means and domain partition member.When domain is cut apart; At first use figure decision means and device component, the figure and the device that are on the cut-off rule are judged, can do indivisible sign the figure and the device that are on the cut-off rule; Avoid cutting apart domain is brought destruction; Figure and device to being in fully within the cut zone are done dividing processing by partition member, produce the domain make new advances, are on the cut-off rule shielded figure and device simultaneously and put together; Produce a new domain, finally be partitioned into plurality of sub domain and a shielded public domain to a domain.
Specify figure decision means among the present invention below in conjunction with embodiment, the implementation method of device decision means and domain partition member.
As shown in Figure 2, the input of figure decision means comprises, domain title, domain cut zone and graphic attribute.Pattern selector is realized jointly that by figure selecting functional part and two information gathering parts the parameter of giving the figure selecting functional part here comprises the domain title, selects zone and graphic attribute.Selected figure is input to figure and chooses in the information gathering parts, and is masked as the figure that can cut apart, and unchecked figure is put into figure and do not chosen the information gathering parts, and is flagged as protected figure.
As shown in Figure 3, the input of device decision means comprises, domain title and domain cut zone and device attribute.The device selector switch is realized by device selection function part and two device information collecting parts jointly, comprises the domain title for the parameter of device selection function part here, selects zone and device attribute.Selected device is admitted to device and chooses the information gathering parts, and is masked as the device that can cut apart, does not choose device to put into device and does not choose the information gathering parts, and be masked as protected device.
As shown in Figure 4, the output that is input as four information gathering parts of domain partition member comprises that figure chooses information gathering parts, figure not to choose information gathering parts, device to choose information gathering parts and device not to choose the information gathering parts.The domain partition member is realized by creating domain functional part and locomotive function parts; Before domain is cut apart; Create two new domains by creating the domain functional part; Choose information gathering parts and device to choose the domain after one of the common generation of information gathering parts is cut apart in figure by the locomotive function parts, do not choose information gathering parts, device not to choose the new domain of the common generation of information gathering parts, generate and cut apart the shielded public domain in back by locomotive function parts and figure; Domain is divided into some the most at last, and wherein not selected figure and device are put into same shielded public domain all the time.
The above is merely preferred embodiment of the present invention, only is illustrative for the purpose of the present invention, and nonrestrictive.
Claims (4)
1. a device of cutting apart domain comprises figure decision means, device decision means and domain partition member, it is characterized in that; When domain is cut apart, at first use figure decision means and device decision means, figure and device are judged; Figure and device to being on the cut-off rule are done indivisible mark; Avoid domain is brought destruction, the figure and the device that are in fully within the cut zone are done dividing processing by partition member, produce the domain that makes new advances; Also can put together simultaneously, produce a shielded public domain being on the cut-off rule shielded figure and device.
