Book Synopsis Technology Mapping for LUT-Based FPGA by : Marcin Kubica
Download or read book Technology Mapping for LUT-Based FPGA written by Marcin Kubica and published by Springer Nature. This book was released on 2020-11-07 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers selected topics of automated logic synthesis dedicated to FPGAs. The authors focused on two main problems: decomposition of the multioutput functions and technology mapping. Additionally, the idea of using binary decision diagrams (BDD) in these processes was presented. The book is a scientific monograph summarizing the authors’ many years of research. As a result, it contains a large number of experimental results, which makes it a valuable source for other researchers. The book has a significant didactic value. Its arrangement allows for a gradual transition from basic things (e.g., description of logic functions) to much more complex issues. This approach allows less advanced readers to better understand the described problems. In addition, the authors made sure that the issues described in the book were supported by practical examples, thanks to which the reader can independently analyze even the most complex problems described in the book.

Available in PDF, EPUB and Kindle. Book excerpt: In the second phase we re-inforce the results obtained in the first phase by a timing driven placement using a simulated annealing formulation. In this phase we minimize critical wirelengths and also control the non-critical wirelengths by assigning wirelengths required at each wire to achieve zero-slack. We then, proceed to achieve this goal via simulated annealing based placement. The outcome of the second phase is a set of placement and routing constraints which are then passed along with the mapped design of the first phase to the actual FPGA placement and route tools (Xilinx-apr [12]).

Book Synopsis Routability-driven Technology Mapping for Lookup Table-based FPGAs by : Martine Schlag
Download or read book Routability-driven Technology Mapping for Lookup Table-based FPGAs written by Martine Schlag and published by . This book was released on 1992 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "A new algorithm for technology mapping of LookUp Table-based Field-Programmable Gate Arrays (FPGAs) is presented. It has the capability of producing slightly more compact designs (using less cells (CLBs)) than some existing mappers. More significantly, it has the flexibility of trading routability with compactness of a design. Research in this area has focussed on minimizing the number of cells. However, minimizing the number of cells without regard to routability is ineffective. Since placement and routing is really the most time-consuming part of the FPGA design process, producing a routable design with a slightly larger number of cells is preferable than producing a design using fewer cells which is difficult to route, or in the worst case unroutable. We have implemented our algorithm in the Rmap program, and studied routability of two other mappers with respect to Rmap in this paper. In general Rmap produces mappings with better routability characteristics, and more significantly Rmap produces routable mappings when other mappers do not."

Book Synopsis On Area/depth Trade-off in LUT-based FPGA Technology Mapping by : Jason Cong
Download or read book On Area/depth Trade-off in LUT-based FPGA Technology Mapping written by Jason Cong and published by . This book was released on 1992 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the core of the area minimization step, we have developed a polynomial-time optimal algorithm for computing an area-minimum mapping solution without node duplication for a general Boolean network, which makes a significant step towards complete understanding of the general area minimization problem in FPGA technology mapping. The experimental results on MCNC benchmark circuits show that our solution sets outperform the solutions produced by many existing mapping algorithms in terms of both area and depth minimization."

This book was released on 1995 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "In this paper, we study the problem of decomposing gates in fanin-unbounded or K-bounded networks such that the mapping solutions computed by a depth-optimal mapper have minimum depth. We present several theoretical results: (1) any further decomposition of a K- bounded network will lead to an optimal mapping depth smaller than or equal to that of the original network, regardless of the decomposition algorithm used, and (2) the problem of gate decomposition for depth-optimal technology mapping is NP-hard for fanin-unbounded network when K>= 3 and remains NP-hard for K-bounded networks when K>= 5. We propose a novel gate decomposition algorithm, named DOGMA, which combines level-driven node packing technique (Chortle-d) and the network flow based optimal labeling technique (FlowMap) for depth-optimal technology mapping. Experimental results show that the networks produced by DOGMA allow depth-optimal technology mappers to improve the mapping solutions by up to 11% in depth and up to 35% in area comparing to the mapping results of networks decomposed by other existing decomposition algorithms."

Book Synopsis FPGA Technology Mapping for Fracturable Look-up Table Minimization by : David Robert Dickin
Download or read book FPGA Technology Mapping for Fracturable Look-up Table Minimization written by David Robert Dickin and published by . This book was released on 2011 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern commercial Field-Programmable Gate Array (FPGA) architectures contain lookup-tables (LUTs) that can be "fractured" into two smaller LUTs. The potential to pack two LUTs into a space that could accommodate only one LUT in traditional architectures complicates FPGA technology mapping's resource minimization objective. Previous works introduced edge recovery techniques and the concept of LUT balancing, both of which produce mappings that pack into fewer fracturable LUTs. We combine these two ideas and evaluate their effectiveness for one commercial and four academic FPGA architectures, all of which contain fracturable LUTs. When combined, edge-recovery and LUT balancing yield a 9.0% to 16.1% reduction in fracturable LUT use, depending on the architecture. We also present a modified technology mapping algorithm called MO-Map that reduces fracturable LUT utilization by 9.7% to 17.2%.

This book was released on 1997 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "A major drawback of the previous technology mapping algorithms for lookup-table based FPGAs is the lack of a fast, and reasonably accurate evaluation scheme to direct the decomposition procedure. Therefore, most of the previous decomposition algorithms have used very simplistic evaluation schemes. It has been shown that decomposition has significant impact on the quality of the final mapping result. In this paper, we propose an iterative technology dependent decomposition and covering algorithm for LUT minimization in FPGA technology mapping. We use a very fast covering algorithm as the evaluation engine to guide the decomposition phase. A BDD-based decomposition technique is developed and used as part of the proposed algorithm. By properly setting the control parameters, our algorithm can turn into a very fast technology mapping algorithm for LUT minimization, which can be used as an accurate prediction tool to provide quick feedback to the higher levels in the FPGA design hierarchy. Furthermore, we will show that our algorithm provides a framework to allow controllable trade- off between the running time and the mapping quality. Experiments on a large number of MCNC benchmark circuits show significant improvement on the number of LUTs and CLBs, compared to all the previous techniques. We have improved the number of LUTs by 6% to 76%, and the number of CLBs by 14% to 59% on the average, compared to the best previously reported results. The results of experiments verify the effectiveness and accuracy of the proposed prediction methodology. Our proposed prediction algorithm achieves results with an average of 8% more LUTs compared to the high quality results, in time that is two orders of magnitude faster."
