Circuit design fitting for an integrated circuit is described. A mapped design for the circuit design is obtained. A first placement of the mapped design in association with an integrated circuit is performed. Circuit blocks are marked associated with the integrated circuit with control set identifiers. A circuit object is associated with a control set identifier. A site for placement of the first circuit object is located. The site is associated with a circuit resource block, which is associated with circuit resource blocks of the integrated circuit. Nearest neighbor circuit resource blocks with respect to the circuit resource block are acquired. The nearest neighbor circuit resource blocks of the circuit resource block are categorized in response to statuses. The circuit object is placed in a nearest neighbor of the nearest neighbor circuit resource blocks of the circuit resource block for a second placement.
