Silicon compilation

Silicon compilation is a term used for many different purposes. In this paper we define silicon compilation as a mapping from some higher level description into layout. We define the basic issues in structural and behavioral silicon compilation and some possible solutions to those issues. Finally, we define the concept of an intelligent silicon compiler in which the compiler evaluates the quality of the generated design and attempts to improve it if it is not satisfactory

A parallel algorithm for global routing

A Parallel Hierarchical algorithm for Global Routing (PHIGURE) is presented. The router is based on the work of Burstein and Pelavin, but has many extensions for general global routing and parallel execution. Main features of the algorithm include structured hierarchical decomposition into separate independent tasks which are suitable for parallel execution and adaptive simplex solution for adding feedthroughs and adjusting channel heights for row-based layout. Alternative decomposition methods and the various levels of parallelism available in the algorithm are examined closely. The algorithm is described and results are presented for a shared-memory multiprocessor implementation

Layout area models for high-level synthesis

Traditionally, the common cost functions, the number of functional units, registers and selector inputs, are used in high level synthesis as quality measures. However, these traditional design quality measures may not reflect the real physical design. To establish quality measures based on the physical designs, we propose layout estimation models for two commonly used data path and control layout architectures. The results show that quality measures deriving from our models give an accurate prediction of the final layout. The results also show that traditional cost functions are not good indicators for optimization in high level synthesis
