Technical field
The present invention relates to EDA design field more particularly to a kind of methods that domain lattic point problem is repaired in online stratification.
Background technique
Virtuoso(IC design software) be Cadence(eda software supplier) circuit released, domain sets
Meter tool.Layout design personnel can make full use of this tool, and the technology library for relying on each technique manufacturer to provide completes various domains
Design.After completing domain body design, it is understood that there may be lattice point mistake leads to not check by drc.In order to solve domain figure
Shape, instance, mosaic etc. be not in lattice point, and the problem of (design ruler check) can not be checked by drc, domain is set
It needs to carry out in meter to carry out lattice point reparation to problematic domain.Currently, realizing such modification operation, traditional way mainly has
3 kinds:
1: the tool carried using laker
1) the lattic point problem reparation that the included tool of laker can not carry out stratification needs when there are the lattic point problem of stratification
Designer intervenes manually, is checked one by one, and design risk is brought, and efficiency is also suppressed.
2) there is a problem of with virtuoso industry mainstream tool interaction, need repeatedly to carry out work, the mistake such as to import and export
Journey is more loaded down with trivial details, low efficiency, also error-prone.
Due to there is excessive manpower intervention, careless mistake can be inevitably introduced, whole process is time-consuming and laborious, and accuracy cannot also protect
Card, limits the efficiency of layout design.
2: the method for repaired by hand
Manual method carries out lattic point problem reparation, maximum problem, be need to expend time of magnanimity under efficiency is very low could
It completes.And the reason due to carrying out lattic point problem reparation manually, introducing careless mistake that inevitably can be artificial, lead to drc problem, even
It is lvs (layout versus schematic) problem, even more needing to expend the regular hour goes misarrangement, and whole process is extremely
Time-consuming and laborious, accuracy also cannot be guaranteed, and significantly limit the efficiency of layout design.

4) unit for having lattic point problem is deleted, this element is re-called, and guarantees that placement direction position is basic consistent with original image.
The realization step of whole process is more cumbersome, and is related to more repetitive operation.Slightly neglect, will introduce
DRC, LVS problem.
2.2 manpower interventions are excessive
Since entire repair process is extremely loaded down with trivial details, data volume is very big, it is likely that the case where not repairing there are some figures needs
When repeatedly carrying out calibre inspection, it could finally eliminate and finish.When layout data is larger, carrying out calibre inspection will consume
Take a large amount of time.Simultaneously as manpower intervention is excessive, when operation, inevitably introduces artificial fault, causes to generate new drc,
Lvs problem.Because project is substantially at the node later period, very big pressure can be brought to project team, in some instances it may even be possible to the delay time at stop
Point.
2.3 file locking
When file, which exists, to be locked, the permission write to file can not be obtained, the modification operation of domain can not be carried out.Need designer
Manually by the way of order line, the position of lock file is found step by step, and deleted.Whole process is more loaded down with trivial details, works as lock
Determine file it is more when, one by one search delete can take considerable time.
3: the method that GDS is imported using cadence virtuoso software
1) use virtuoso software, import or export GDS data when setting DBUPerUU value and " Snap To
Grid " option can carry out the reparation of lattic point problem, but simultaneously, it has certain problems, in importing or export process
In, the unit of parametrization can be tied, such as the standard block of pcell or parametrization, cause other users carry out reference and
It when change, has certain problems, can not easily carry out the modification and re-using of parameter.
