Security tab

In designs that use the Quartus^® Prime Standard Edition Design Separation flow with CycloneIII LS devices, the Security tab allows you to assign security attributes to signals entering or exiting secure LogicLock regions.

• Security attribute— Allows you to specify the Security attribute of the currently selected LogicLock region.
• Security Routing Interface— Specifies that only routing resources can be assigned to the currently selected LogicLock region. A LogicLock region with its Security Attribute set to Security Routing Interface creates a routing channel to and from a secured region (a LogicLock region with Security Attribute set to 1 or 2). Each signal entering or leaving a secured region must be assigned to a security routing interface with the Security tab of the LogicLock Regions Properties dialog box.

• Unsecured— Specifies that the currently selected LogicLock region is unsecured. LABs bordering the currently selected LogicLock region can be used in the design.
• 1— Specifies that the currently selected LogicLock region is secured. Creates a fencing region (with a LAB width of one) around the currently selected LogicLock region. LABs within the fencing region cannot be used in the design.
