This panel, which is polymorphic and specific for each design rule
type, appears when a design rule is edited or a new rule is being
created from the Design Rule Editor panel. It provides the
appropriate entry areas for rule parameters. If the target rule is
changed while the panel is visible, the panel will reconfigure itself
to provide the entries for the new rule.
There are two entries that are common to all rules. The first is
labeled ``Layer expression to AND with source figures on current
layer (optional)''. This is the optional Region specification.
The second is labeled ``Decsription string'', which contains
optional arbitrary text which explains the rule or provides a
reference. This text will appear in violation messages.
The entry areas for the rules are briefly described below. See
the rule descriptions for more information.
- User Defined Rule
- User-defined rule arguments (n required)
An entry area where the rule arguments are entered, separated by
space. The label prints the number of arguments required for the
rule, extra arguments are ignored.
- Connected
No additional entries.
- NoHoles
- Minimum area (square microns)
If larger than 0.0, holes with smaller area will trigger an
error. If 0.0, any hole will trigger an error.
- Target layer name or expression
This is the name of a layer, or a layer expression, which is the
target for the rule. An entry is mandatory.
- MinArea
- Minimum area (square microns)
This specifies the minimum area for the rule.
- MaxArea
- Maximum area (square microns)
This specifies the maximum area for the rule.
- MinEdgeLength
- Target layer name or expression
This is the name of a layer, or a layer expression, which is the
target for the rule. An entry is mandatory.
- Minimum edge length (microns)
This specifies the minimum edge length for the rule.
- MaxWidth
- Maximum width (microns)
This specifies the maximum width for the rule.
- MinWidth
- Minimum width (microns)
This specifies the minimum width for the rule.
- Non-Manhattan "diagonal" dimension
If nonzero, this value will be used instead when the measurement
direction is not parallel to the x or y axis.
- MinSpace
- Minimum spacing (microns)
This specifies the minimum space for the rule.
- Non-Manhattan "diagonal" dimension
If nonzero, this value will be used instead when the measurement
direction is not parallel to the x or y axis.
- Same-Net dimension
If nonzero, this value will be used instead when the measurement
is between objects in the same wire net.
- MinSpaceTo
- Target layer name or expression
This is the name of a layer, or a layer expression, which is the
target for the rule. An entry is mandatory.
- Minimum spacing (microns)
This specifies the minimum space for the rule.
- Non-Manhattan "diagonal" dimension
If nonzero, this value will be used instead when the measurement
direction is not parallel to the x or y axis.
- MinSpaceFrom
- Target layer name or expression
This is the name of a layer, or a layer expression, which is the
target for the rule. An entry is mandatory.
- Minimum dimension (microns)
This specifies the minimum projection for the rule.
- Dimension when target objects are fully enclosed
If nonzero, this value will be used to test objects that
are fully surrounded.
- Opposite side dimensions
If at least one of the two numbers is nonzero, these will be used to
test fully enclosed boxes. Two opposite sides must be exclosed by at
least one value, and the other two sides must be enclosed by at least
the other value.
- MinOverlap
- Target layer name or expression
This is the name of a layer, or a layer expression, which is the
target for the rule. An entry is mandatory.
- Minimum dimension (microns)
This specifies the minimum overlap width for the rule.
- MinNoOverlap
- Target layer name or expression
This is the name of a layer, or a layer expression, which is the
target for the rule. An entry is mandatory.
- Minimum dimension (microns)
This specifies the minimum projection for the rule.
