Assign different routing design rules to different areas
The Rules-by-Area package is a powerful extension to the CADSTAR P.R.Editor XR 2000 tool-set that enhances Zuken’s routing technology by allowing the association of different design rules to different areas of the design.
With Rules-by-Area, tracks can be reduced in width according to the rules defined by the area they are routed through. It is now possible to execute the routing manually or automatically. Other rules that can be defined for specific areas include via sizes and also the use of blind or buried via technology.
Spacing rules for any area may be redefined which is especially useful around small complex dense components such as BGAs, Wire Bonded CSPs and SMDs allowing for 100% error free routing.
High speed routing will also obey the rules defined by the area. There is no limit to the number of areas that may be defined, and these areas may be of any shape and on any
Top features and benefits
- Benefits you when you are forced to
compromise your design rules when
- Helps you when yield is a problem in
the design of fine-pitch devices
- Incorporate overlapping areas that can
be any shape into your designs
- Lets you copy areas, while also
obtaining and copying the associated
technology restriction rules.
Design Rule Checks by Area
Required routing rules for each area are added in
CADSTAR. The designer can take advantage of the online
design rules checking feature in P.R.Editor, while routing
in areas with the alternative rules set. This will highlight
any error condition as defined by the rules for the current
area with the further advantage that all areas may be
routed error free without the need to change the routing
rules that are obeyed.
Knowing that all the design rules will be obeyed, the
designer can auto-route the entire PCB, or route manually
with the tool highlighting any non-compliance to the preset
Fully definable rule sets per area
For each area that is placed on the design you can set different track
spacing, net routing widths and a via sizes. This gives outstanding routing
flexibility when specifying and using micro-vias, fine-line and very small
tracks, vias and pad spacing.
