Hello World,
(Protel 99SE, SP6)
I have some strange situations with the DRC check in PCB. I have a 'routing'
rule 'Routing Via Style'.
The scope of the rule is 'Whole Board', the attributes set some limits on
the size of the via and the hole.
If i do some manual routing then the preferred sizes are used, this is the
expected situation.
But now the problem, after changing the properties of the via to a size wich
is outside the rule limits there is no warning from DRC report.
The rule is enabled and in the Report tab of the Design Rule Check dialog I
have enabled all the checkboxes. The report file shows no problems, it tells
that it has processed 'Clearance Constraint' rules and some other rules but
I can't find any line wich has to do with the via rule.
The next thing I tried was exporting the rules.
Design Menu, Rules, Click the Button 'Menu' at the bottom of the dialog and
then choose 'Report Rules.
First I did a report with al the checkboxes marked. A snip of the report is
this:
<<<
Used Rules :
Enabled = Yes Name = Width_1
Scope = Board
Minimum = 13mil
Maximum = 50mil
Preferred = 13mil
Rule Followed By Router
Enabled = Yes Name = RoutingVias_1
Scope = Board
Min H. Size = 28mil
Max H. Size = 28mil
Pref. H. Size = 32mil
Min Width = 50mil
Max Width = 50mil
Pref. Width = 162mil
Style =
Rule Followed By Router
>>>
The first rule in the above snip is not a problem, if I have a track width
of 10 mil or 100 mil then it is reported in the DRC report.
I don't know why the via rule doesn't work
Then I noticed a second strange situation. If I do a rule report with the
following settings:
Sections: only the 'Used Rules' checked
Rule types: all check boxes marked
then I get a very short report file with the text:
<<<
Protel Design System Design Rule Check
PCB File : Elektronics\SGM9230\Copy of SGM9230.PCB
Date : 1-Mar-2001
Time : 17:25:34
Used Rules :
Total Used Rules : 0
Time Elapsed : 00:00:00
>>>
Very strange I think, maybe someone can help me.
For me the working hours are done for this day, I will go home now and hope
that Protel users at the other side of the world will solve my problem while
I am sleeping :-))
