Another question for the group.
How do I set up "Line-to-Line spacing" of one dif pair to anything else?
|
|
Min Line Spacing:
![]()
|
|
|
![]()
I tried setting MIN LINE SPACING to 20mil, but it wants this to be less
than specified gap.
I want Gap (10mil) and width (4mil) as specified, but dp to anything
els to be (20mil).
Do I have to set as NET_SPACING_TYPE?
Thanks,
Mark

I want 1500mil shorter than target as minimum length and target length
as max.
I think I will use -750:750 suggested by Daniel so my actual target is
in the middle of the spec.
Thanks for all the responses.
Mark
the specified nets to be matched to the taget length as a max and
1500mil shorter than the target as min.

Mark,
If you want the specified net to be 1500 mil shorter than the target,
you need to set the delta to -1500. The tolerance is then applied to
the length.

Can anyone tell me the correct way to define a matched group in
Constraint Manager?
I need to match a target to "same length as target" to "-1500mil of the
target"?
I tried 0:-1500 for delta:tolerance, but it is not working right.
Thanks in advance,
Mark
