AWB/LEAP for FPGA Design

AWB is tool for facilitating the modular plug-n-play style construction of software and hybrid software/hardware projects. It was originally written to create software performance models within the Asim performance modeling infrastructure. AWB's origin as part of Asim is the reason for the many references to Asim in the documentation and tools themselves. AWB has, however, been extended to be a more general tool for constructing a variety of projects where selection of alternative implementations of modules in a plug-n-play manner is advantageous. In specific, AWB now supports hybrid hardware/software designs. The first of these was the HAsim modeling infrastructure, but a variety of other more general designs are currently using AWB.

Asim was developed by Compaq researchers in late 1998 to allow model writers to faithfully represent the detailed timing of set of issues identified during two standards efforts: the IEEE Std. 1061-1998 for a Software Quality Metrics Methodology and the American National Standard Recommended Practice for Software Reliability (ANSI/AIAA R-013-1992). The second approach ties these knowledge requirements to phases in the software development life cycle. Together, these approaches define a bodyof knowledge that shows software engineers why and when to measure quality. For detail, see

LEAP is a Virtual Platform that provides a consistent set of interfaces and functionalities to an FPGA application across a range of physical FPGA platforms. For the detail, see
