Three-dimensional Field Programmable Gate Arrays (3D FPGAs) represent a viable alternative to overcome challenges of integration complexity in modern embedded systems. Mapping applications into 3D FPGAs requires a set of accompanying suite of Computer-Aided Design (CAD) tools. One of critical issue of a 3D FPGA-based implementation is the quality and efficiency of associated CAD algorithms. In this...
This paper proposes to use the high density of vias enabled by monolithic 3D integration to produce multi-stack FPGA designs with improved performance and functionality. The use of fine grain vertical interconnects enables reconfiguration of FPGA logic within a few clock cycles, as shown in our design that features dynamic reconfiguration capabilities through the use of a pair of configuration memories...
In this paper we propose a three-dimensional (3D) interconnect network implementation based on a modified Mesh-of-Trees (MoT) topology for FPGA architecture design. To obtain the optimal MoT-based interconnect structure, the routing architecture of the 2D MoT-based FPGA is modified to include long routing segments that span multiple switch blocks in every row and column. By adjusting the percentage...
Three-Dimensional (3D) FPGA as a promising design trend, achieves significant performance improvement over conventional 2D-based FPGA. The maturity of the uni-directional routing architecture design, which achieves 25% area saving in area-delay-product (ADP) over bi-directional routing architectures, has driven major vendors such as Xilinx and Altera to switch to such architecture in their 2D-based...
Power becomes an ever-increasing concern due to the growing design complexity and the shrinking process technology. Power estimation at an early stage of electronic design automation (EDA) flow is essential in order to handle the design issues much earlier. Also power due to the routing resources is a dominant in field-programmable gate arrays (FPGAs). In this paper, we introduce a methodology for...
