To facilitate the development of future FPGA architectures and CAD tools -- both embedded programmable fabrics and pure-play FPGAs -- there is a need for a large scale, publicly available software suite that can synthesize circuits into easily-described hypothetical FPGA architectures. These circuits should be captured at the HDL level, or higher, and pass(More)
Exploring architectures for large, modern FPGAs requires sophisticated software that can model and target hypothetical devices. Furthermore, research into new CAD algorithms often requires a complete and open source baseline CAD flow. This article describes recent advances in the open source Verilog-to-Routing (VTR) CAD flow that enable further research in(More)
VTR is an open source academic FPGA CAD flow designed for exploration of hypothetical FPGA architectures. High level language and architectural feature support are of continuing importance to researchers using the VTR flow to explore these architectures. In this paper we will discuss the extension of VTR to support implicit memories and the elaboration of(More)
From Roman gladiatorial combat to Egyptian animal mummies, the capture and manipulation of carnivores was instrumental in helping to shape social hierarchies throughout the ancient world. This paper investigates the historical inflection point when humans began to control animals not only as alimental resources but as ritual symbols and social actors in the(More)
Human-animal interactions have played crucial roles in the development of complex societies across the globe. This study examines the human-leporid (cottontail and jackrabbit) relationship at the pre-Hispanic (AD 1-550) city of Teotihuacan in the Basin of Mexico and tests the hypothesis that leporids were managed or bred for food and secondary products(More)
