Conference paper (peer-reviewed)abstract
- This paper describes the restructuring of VLSI education at the Royal Institute of Technology (KTH). Changing needs of industry, advances in technology and design methodology has required a significant reorganization of VLSI education with combined emphasis on system issues and associated physical constraints. We present here a course structure which will address, in parallel fashion, the key design issues for future system products

Interconnect-centric design for advanced SoC and NoC
- 2005
-
Editorial collection (peer-reviewed)abstract
- In Interconnect-centric Design for Advanced SoC and NoC, we have tried to create a comprehensive understanding about on-chip interconnect characteristics, design methodologies, layered views on different abstraction levels and finally about applying the interconnect-centric design in system-on-chip design. Traditionally, on-chip communication design has been done using rather ad-hoc and informal approaches that fail to meet some of the challenges posed by next-generation SOC designs, such as performance and throughput, power and energy, reliability, predictability, synchronization, and management of concurrency. To address these challenges, it is critical to take a global view of the communication problem, and decompose it along lines that make it more tractable. We believe that a layered approach similar to that defined by the communication networks community should also be used for on-chip communication design. The design issues are handled on physical and circuit layer, logic and architecture layer, and from system design methodology and tools point of view. Formal communication modeling and refinement is used to bridge the communication layers, and network-centric modeling of multiprocessor on-chip networks and socket-based design will serve the development of platforms for SoC and NoC integration. Interconnect-centric Design for Advanced SoC and NoC is concluded by two application examples: interconnect and memory organization in SoCs for advanced set-top boxes and TV, and a case study in NoC platform design for more generic applications.

A rule-based approach for improving allocation of filter structures in HLS
- 1996
-
In: Ninth International Conference on VLSI Design, 1996. Proceedings. - : IEEE conference proceedings. - 0818672285 ; , s. 133-139
-
Conference paper (peer-reviewed)abstract
- A rule based allocator for improving synthesis of filter systems is presented. The principles of the Enhanced AIlocation Rule Language Interpreter (EARLI) are presented. Possible transformations, optimisations and how to express them in EARLI are discussed. Experiments show that relative area gains ranging from 5 to 44%, depending on the chosen target technology, can be achieved using the designers knowledge about the design class. Experiments also indicate that employing direct mapping of CDFG subgraphs onto preoptimised RTL-level macroblocks would have resulted in a relative area gain of 500%. The macroblock had only 16% of the area produced by the HLS-tool
