Virtuoso Routing Constraint Manager

---

The Virtuoso Routing Constraint Manager (RCM) provides a simplified and consolidated interface for managing routing constraints.

The following are some of the key features of the Routing Constraint Manager.

• Supports a prioritized set of constraints for routing
• Provides a simplified spreadsheet view of all routing constraints in the design
  • Lets you customize columns for constraint types    
  • Provides ability to view by net or by constraint type  
  • Provides ability to search, filter, and apply defaults 
  • Lets you add and modify constraints 
• Specifies additional parameters for specific constraints 
  • Exposes parameter fields for a given constraint type to edit them in place 
  • Lets you save and reuse settings for a constraint to apply to other nets or design 
• Abstracts database and implementation details from user (for example, constraint group specifics) 
• Stores constraints directly in OpenAccess as part of the design layout view
• Lets you start a constraint checker to visualize the constraint implementation status 

Using RCM, you can filter the nets based on the constraints definition status, signal nets, power nets, and so on. You can create design-level constraint groups and apply them to specific design objects. You can create shielding constraint groups and apply them to specific nets in the design.
