The expert committee that(More)
High-level functional (or behavioral) simulation models are difficult, time-consuming, and expensive to develop. We report on a method for automatically generating the program code for a high-level functional simulation model. The high-level model is produced directly from the program code for the circuit components' functional models and a netlist(More)

Focusing especially on the later stages of the design task, when a complete (or nearly so) design is being optimized at the structural level prior to final physical layout, we identify some aspects of the VLSI domain which complicate efficient design both for human and machine agents. We describe a simple but useful idea and a prototype implemented system(More)
The Airport Improvement Program (AIP) has been providing federal grants for airport development and planning since the passage of the Airport and Airway Improvement Act of 1982 (P.L. 97-248). AIP funding is usually spent on projects that support aircraft operations such as runways, taxiways, aprons, noise abatement, land purchase, and safety or emergency(More)
The major highways and bridges damaged during Hurricane Irene in 2011and the I-35W bridge collapse in Minneapolis of August 1, 2007 are part of the federal-aid highway system and were therefore eligible for assistance under the Federal Highway Administration's (FHWA's) Emergency Relief Program (ER). Following a natural disaster or catastrophic failure (such(More)
When Hurricane Katrina swept across the Gulf of Mexico coast and into Louisiana, Mississippi, and Alabama, its winds, storm surge, and flooding did significant damage to the road and bridge infrastructure in the coastal areas of these states. Most of the major highways in the disaster area are part of the Federal-Aid highway system and are therefore(More)
