Fig. 2 is the robotization generator high-level schematic functional block diagram of the DRC file of one embodiment of the invention.
Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Embodiment one
As shown in Figure 1, the invention provides a kind of robotization production method of DRC file, comprise step S1～step S5.
Step S1, will based on same design technology and need same a kind of DRC code of reusable semi-conductive different designs technology level write one can repeat to call grand in.
Preferably, described repeat to call grand obtains two variate-values, and described variate-value is respectively numbering and the corresponding process inspection parameter value of technology level.
For example, can set up following grand (macro) that repeats to call:
#defmacro?min_width($<layer>,$<value>)
INT$<layer><$<value>ABUT<90SINGULAR?REGION
#end_macro
Wherein, min_width represents grand title, and layer represents the numbering of technology level, and value represents the process inspection parameter value corresponding to the numbering of this technology level.
Follow-uply be written as #macro min_width (AA when in the DRC file, needing call macro min_width, 0.06), wherein the numbering of technology level (layer) is AA, corresponding process inspection parameter value (value) is 0.06, call this grand min_width after the result be INT AA＜0.06ABUT＜90SINGULAR REGION.So just can realize based on same design technology and need the calling of same a kind of DRC code of reusable semi-conductive different designs technology level, can be so that all slip-stick artists' code form be all consistent, particularly for some more complicated based on same design technology and need the literary style of same a kind of DRC code of reusable semi-conductive different designs technology level, make mistakes easily, after adopting originally can repeat to call grand, can reduce error rate greatly.
Further rapid, step S1 can, described repeat to call grand obtains the numbering of described technology level by a recursive call document, described recursive call document comprise process layer time Base Serial Number, stop three variablees of numbering and numbering space-number.
For example, can set up following recursive call document:
#loop(1,$2-,1)
M#=M#i?OR?M#dum
#end_loop
Wherein, loop (1 ， $2-, 1) 1 in,, 1 represents Base Serial Number, termination numbering and the numbering space-number of technology level successively, $2-is that the sum of technology level deducts 2, if the technology level of semiconductor add up to 10, then the termination of corresponding technology level is numbered 10-2=8.Follow-up when the DRC file calls above-mentioned repeat to call grand, this grand recursive call document that further calls present embodiment obtains the numbering of the technology level of following 8 different metals:
M1=M1i?OR?M1dum
M2=M2i?OR?M2dum
M3=M3i?OR?M3dum
M4=M4i?OR?M4dum
M5=M5i?OR?M5dum
M6=M6i?OR?M6dum
M7=M7i?OR?M7dum
M8=M8i?OR?M8dum
In addition, if wishing the Base Serial Number of technology level is 2, the termination of technology level is numbered 10, the numbering space-number is 3, then can be written as loop (2, $, 2), follow-up when the DRC file calls above-mentioned repeat to call grand, this grand recursive call document that further calls present embodiment obtains the numbering of the technology level of following 5 different metals:
M2=M2i?OR?M2dum
M4=M4i?OR?M4dum
M6=M6i?OR?M6dum
M8=M8i?OR?M8dum
M10=M10i?OR?M10dum
As long as can write the DRC file of one deck technology level like this, just can obtain the DRC file of all technology levels, and DRC file editor must be more complicated, improved efficiency is more obvious.
Step S2 will and need the two or more DRC codes of reusable semi-conductive different designs technology level to write in the condition selection inspection document that can repeat to call based on same design technology.
For example, a condition that can repeat to call selects to check that document A.R.5 is as follows:
Follow-uply after selecting to check document A.R.5, the above-mentioned condition of the adjustable usefulness of DRC file obtains following result:
For metal 1:
But can realize sharing of the similar code of DRC file part like this.
Step S3 writes a technology category that can repeat to call with the two or more DRC codes of the reusable different designs technology of needs and selects to check in the document.
For example, a technology category selects to check that document is expressed as follows:
#process=～A
Code?A
#else_process=～B
Code?B
#end_process
Follow-up after the above-mentioned technology category of the adjustable usefulness of DRC file is selected to check document, obtain following result:
When being technology A, call Code A, when being technology B, call Code B.Can realize a Edit Document of DRC file sharing of different designs technology like this, reduce the maintenance documentation amount, also can code sharing between different designs technology.
Step S4 gathers all DRC codes of semi-conductive each technology level respectively and to write each technology level technology level that repeats to call separately and gather and check in the document.
For example, three technology levels can setting up the technology level respectively and be aa, bb and cc gather the inspection document, follow-uply gather the inspection document at above-mentioned three the technology levels of the adjustable usefulness of DRC file:
#include?layer_aa
#include?layer_bb
#include?layer_cc，
To comprise layer_aa in the DRC file like this, layer_bb, all codes of layer_cc.
In other embodiments of the invention, the order of above-mentioned steps S1～step S4 can be changed arbitrarily.
Step S5, require to generate the DRC file according to DRC, described inspection file comprises that described grand, the condition selection that repeats to call checks that document, technology category selection check that document and technology level gather a kind of or combination in any that checks in the document, thereby promote the editorial efficiency of DRC file, significantly reduce the maintenance of code, make the maintenance of code have more efficient.
For example, the source code of a DRC file of safeguarding is 627 row, practical application can be walked to 1583 capable 10 parts of demand files that do not wait according to the source code generation 881 of described DRC file again then, follow-up this 10 parts of demand files of revising if desired, only need make amendment to the source code of this a DRC file in the present embodiment and can realize need not modification to these 10 parts of demand files 10 parts of demand files are made amendment one by one.
Present embodiment is applied to the editor of 65nm ANTENNA DRC rule, 65nm LEF file and metal slotrule, can greatly promote the maintenance efficiency of document, satisfies client's demand fast.
Embodiment two

The macroblock 1 that can repeat to call is used for carrying out the same a kind of DRC code based on same design technology and the reusable semi-conductive different designs technology level of needs.
Preferably, the described macroblock that repeats to call 1 obtains two variate-values, and described variate-value is respectively numbering and the corresponding process inspection parameter value of technology level.
Further, the described macroblock that repeats to call 1 obtains the numbering of described technology level by a recursive call module 6, described recursive call module comprises three variate-values, and described variate-value is respectively Base Serial Number, termination numbering and the numbering space-number of technology level.
The condition that can repeat to call selects to check module 2, is used for carrying out based on same design technology and needs the two or more DRC codes of reusable semi-conductive different designs technology level.
The technology category that can repeat to call selects to check module 3, is used for carrying out the two or more DRC codes of wanting reusable different designs technology.
The technology level that can repeat to call gathers inspection module 4, is used for carrying out respectively all DRC codes of semi-conductive certain technology level.
Generation module 5, be used for generating the DRC file according to inspection requirements, described generation DRC file calls the described macroblock that repeats to call, condition selects to check that module, technology category selection check that module and technology level gather a kind of or combination in any that checks in the module.
Other detailed content of embodiment two specifically can not repeat them here referring to embodiment one.
