The present invention is further detailed explanation for detailed description of the invention.
Embodiment one
As it is shown in figure 1, the present invention provides the automatic production generation method of a kind of DRC file, including
Step S1～step S5.
Step S1, by based on same design technology and the different designs process layer that needs reusable quasiconductor
Secondary same DRC code write one repeatable call grand in.
Preferably, described repeatable two variate-values of the grand acquisition called, described variate-value is respectively process layer
Secondary numbering and corresponding process inspection parameter value.
Such as, the most repeatable grand (macro) called can be set up:
#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 technique level, and value represents right
Should be in the process inspection parameter value of the numbering of this technique level.
Follow-up it is written as #macro when needing call macro min_width in DRC file
Min_width (AA, 0.06), wherein the numbering (layer) of technique level is AA, and corresponding process inspection is joined
Numerical value (value) is 0.06, and after calling this grand min_width, result is INT AA < 0.06ABUT < 90
SINGULAR REGION.Thus can realize based on same design technology and need reusable half
Calling of the same DRC code of the different designs technique level of conductor, so that all works
The code form of Cheng Shi is all consistent, more complicated based on same design technology and needs especially for some
The literary style of the same DRC code of the different designs technique level of reusable quasiconductor, holds
Error-prone, use this most repeatable call grand after, error rate can be substantially reduced.
The most rapid, step S1 can, described repeatable call grand by one recursive call document obtain institute
State the numbering of technique level, described recursive call document include technique level Base Serial Number, terminate numbering and
Three variablees of numbering space-number.
Such as, following recursive call document can be set up:
#loop(1,$2-,1)
M#=M#i OR M#dum
#end_loop
Wherein, 1,2-, 1 in loop (1,2-, 1) represent successively technique level Base Serial Number, terminate numbering and
Numbering space-number, 2-is that the sum of technique level deducts 2, if the sum of the technique level of semiconductor is
10, the then numbered 10-2=8 of termination of corresponding technique level.Follow-up call above-mentioned at DRC file
Repeatable call grand time, this grand recursive call document calling the present embodiment further, obtain following 8
The numbering of the technique level of different metal:
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
It addition, the Base Serial Number being it desired to technique level is 2, the termination numbered 10 of technique level, compile
Number space-number is 3, then can be written as loop (2,2), follow-up call at DRC file above-mentioned repeatable
Call grand time, this grand recursive call document calling the present embodiment further, obtain following 5 different gold
The numbering of the technique level belonged to:
M2=M2i OR M2dum
M4=M4i OR M4dum
M6=M6i OR M6dum
M8=M8i OR M8dum
M10=M10i OR M10dum
As long as the DRC file of a layer process level so can be write, it is possible to obtain all technique
The DRC file of level, and DRC Document Editing must be the most complicated, and improved efficiency is the brightest
Aobvious.
Step S2, by based on same design technology and the different designs process layer that needs reusable quasiconductor
Secondary two or more DRC codes write a repeatable condition called and select to check in document.
Such as, a repeatable condition called selects to check that document A.R.5 is as follows:
A.R.5_M#{
Code A
#if(#>1)
Code B
#end_if
}
Follow-up DRC file can call above-mentioned condition select to check obtain after document A.R.5 as follows
Result:
For metal 1:
A.R.5_M1{
Code A
}
For metal 2:
A.R.5_M2{
Code A
Code B
}
So can realize DRC file can part similar codes share.
Step S3, it would be desirable to the two or more DRC codes of reusable different designs technique are write
Enter a repeatable technology category called to select to check in document.
Such as, a technology category selects to check that document representation is as follows:
#process=～A
Code A
#else_process=～B
Code B
#end_process
Follow-up after DRC file can call above-mentioned technology category selection inspection document, obtain as follows
Result:
When for technique A, call Code A, when for technique B, call Code B.So can be real
DRC file sharing portion editor's document of existing different designs technique, reduces maintenance documentation amount, also
Code sharing between different designs technique can be realized.
All DRC codes of each technique level of quasiconductor are collected write by step S4 respectively
The respective repeatable technique level called of each technique level collects in inspection document.
For example, it is possible to set up three technique levels that technique level is aa, bb and cc respectively to collect inspection document,
Follow-up can call above three technique level at DRC file and collect inspection document:
#include layer_aa
#include layer_bb
#include layer_cc,
So DRC file will comprise layer_aa, all codes of layer_bb, layer_cc.
In other embodiments of the invention, the order of above-mentioned steps S1～step S4 can arbitrarily be exchanged.
Step S5, requires to generate DRC file, described inspection file bag according to DRC
Include described repeatable grand, the condition called to select to check that document, technology category select to check document and process layer
The secondary one collected in inspection document or combination in any, thus promote the editorial efficiency of DRC file,
