In APD15.7, we can add a constraint area by creating a shape and attach the property. However, I have no idea how to create a constraint area in APD16.2. Anyone can help..
How to set up a constraint region in 16.2.
Lets say we want to create a spacing region:
Open constraint manager and create a Spacing Rule set for the constraint region.1. Open Constraint Manager on the board file.2. Select Spacing > All Layers worksheet 3. RMB on the Objects and select Create Spacing CSet 4. Type the name of Spacing CSet and change the pin to pin constraints that allowpin to pin spacing for the 'special' component.Now create a region and assign a spacing CSet to the region.1. In Constraint Manager, select Region > All Layers 2. RMB > Create Region 3. Give a name to the region, and select Ok.4. On the Region worksheet, select the region that you just created, and assignthe Spacing CSet that you had created in the previous step. The rules of thespacing CSet are automatically taken over by the Region.Now create a Shape on Constraint Area subclass and assign the region rules to it.1. On Allegro, Select Shape > Polygon or Rectangular.2. In the Options panel on the Right hand side, select the Class as ConstraintRegion > All.3. From the drop down in the options panel, select the Region you had defined inthe previous step.4. Draw the rectangle or polygon around the component.
In reply to Jeff Gallagher:
Thanks alot. It works now.
The procedure above is correct, but there is additional options you may wish to choose.
1. The shape(s) for the Region do not have to be drawn on the All subclass of the Constraint Region class. You may create the shapes on any etch layer, or the special layers of Outer Layers (i.e. Top and Bottom), Inner Signal Layers, or Inner Plane Layers.
2. You do not have to use a Spacing Constraint Set for the Region. You only have to specify the constraints that you need specifically for this region. By only specifying the pin-pin constraints that you need, you'll improve the drc performance and you're constraint methodology will be easier to understand.
3. Regions also support Physical and Same Net Spacing constraints.
4. When creating the shape, you can select a Region name from the "Assign to Region" drop down on the Option panel, or you can type in a new name. Any new name will automatically appear in Constraint Manager in the Physical, Spacing, and Same Net Spacing worksheets.
Also, in case you weren't aware, there is no limit to the number of shapes that can be part of a Constraint Region.
Is this method available in OrCAD PCB Disigner 16.0?
I can't find the Region in the Constraint Manager.
I found the Constraint Region Class though.
I need to specify constraint for specific component, how can I do so? if at all possible?
Thanks in advance,
