According to the ITRS roadmap, 70 percent of the area of a typical ASIC today is memory and this increases to over 90 percent by the end of the roadmap. Yet despite the fact that ASICs are becoming more memory-intensive, commodity memory and ASIC design and manufacturing technologies are still on divergent paths. In this report, we examine methodologies for the design of Memory-Based Structured ASICs SASICs that include large amounts of dense, on-chip memory, as well as multiple processing cores, networks-on-chip, and IO modules. We investigate regular fabrics as a means for designing logic circuitry compatible with the lithographic constraints imposed by the memory array for subwavelength geometries. We also develop midrange and high-level tools for exploring tradeoffs in power, area, and timing of complex, multicore SASICs. The report concludes with recommendations for follow-on work in the area of patterned ASICs.
