I want to ask a question about Assura DRC rules writing. Can variables
be defined and assigned to certain value more than once in the same
sequence without problems?
Here's an example:
A=geomAnd(B1 B2)
B=geomAndNot(C1 A1)
;
A=geomAnd(B1 B3)
C=geomOverlap(C2 C3)
;
if (! avSwitch( "Sw1" ) then
keepLayer(B)
)
if( !avSwitch( "Sw2" ) then
keepLayer(C)
)
;
How can A layer be defined twice at the same place!! Which one will be
stored? I can't understand it. It may be error in the rule file. As I
can basically understand, i think that variable A was overwritten and
no longer existing!! Isn't it?
Another question about keepLayer() , I read about it in Assura Command
Reference and unfortunately I couldn't understand that it has an
advantage! And can I consider the VLW as a window to display DRC
errors in it?
I'm originally Calibre user, and am a new user to Assura, so my
questions may look to be very basic, but it will help me a lot if I
got answers on them..
Thanks and best regards,
Ahmad.
