Systems and methods for creating and placing custom guard rings create a guard ring from a plurality of unit cells reflecting the devices that are enclosed in the guard ring. Using a unit cell identified by a design tool user as the basic unit of the guard ring, with a few additional setup parameters, a complete, content-aware guard ring is created. The guard ring will consist of a collection of the identified unit cells placed around the circuit devices that are to be protected. The created guard ring will function as a single circuit component. Edits to the dimensions and/or parameters of the unit cell will affect the placement of the unit cell in the protected area and will therefore require creation of a new guard ring consistent with the changed parameters.
