Abstract :
This paper presents a newly developed computer-aided design (CAD) tool for 3-dimensional field programmable gate arrays (3D-FPGAs). With this tool, primary inputs/outputs (I/Os) are packed in the configurable logic blocks (CLBs) and placed all over the 3D-FPGA. Moreover, rectangular parallelepiped confinement (RPC) and A-star (A*) search algorithms are applied to perform 3D routing, which is about 9.0 times faster than the one not introducing the algorithms, without degrading the routing quality.
