A timing-driven simultaneous placement and floorplanning method based on a multi-layer density system for heterogeneous field programmable gate arrays are disclosed. The field programmable gate arrays are designed with heterogeneous resources including look-up tables, memory blocks and dedicated logic blocks. Each layer in the multi-layer density system is modeled with a different architectural resource. The placement of look-up tables and the floorplan of computational blocks are concurrently determined in the multi-layer density system. A dynamic timing optimization scheme is also seamlessly integrated in the placement process.
