Calibre can't point out all the same error, why?

Hi,

I layed out with virtuoso and run drc check with calibre, I know there's
some via error in my drawing and calibre can find them also, but it only
check out one or several errors at one time, after I modify some, then it
find part of remanent error. I wish calibre can check out all of the same
error once, how should I do it? I can't find anything about in the rule
file. Thanks for your help!

Have a good day!

Best Regards,

Harryzhu
 
You must understand that calibre will find many errors when a via is wrong.
All of the errors may be related in your mind, but to calibre they could be
different events. (Generated by different set of edges!)

But I get only 3 errors, in fact there's about 20 via1 errors. Just after I

modify one error and run again, then it'll find next error.

Hello Harryzhu,

did you check the values of the following variables in the DRC rule file?
DRC MAXIMUM RESULTS
DRC MAXIMUM VERTEX

They limit the number of errors shown in the results file. If you reach
this saturation value, Calibre stops showing additional errors. That may
be another reason, in addition to the previous poster's point, why you
do not get all errors at the first run.

It is hard to comment on your problem, because the behavior depends on
the rule file... Maybe you can tell us what kind of error you have
(offgrid, spacing, ...)

You may also find some advice on Calibre on
http://forums.mugweb.org

Don't forget G's statement: as DRC considers edges and vertex, an error
may hide another one, so that the second can only be detected when the
first is corrected.

I've set 'DRC MAXIMUM RESULTS ALL', and not set 'DRC MAXIMUM', but I modify

the setting in the interactive window to 'ALL'. but all these can't help
me.

I met only the via1 error at last, but it can't check out all the same error
at one time.
