“…19], where the methodology and firing rules are stored in a knowledge-base and an inference engine determines the tool execution sequence. Yoda [20], a filter design system, has a knowledge-base of predictors (estimators). Predictors are used to determine the outcome of applying a particular tool and the results from such an exploration are used to construct a design plan (similar to a script), with feedback from the designer.…”

The system-level design problem spans a large design space. Typically, the designer needs to explore possible target architectures, experiment with different tools, and work with a range of constraints and optimization criteria. This design process is quite complex and involves considerable bookkeeping and management, in addition to sophisticated design tools. We believe that managing the design process is an important (albeit often neglected) part of system-level design. The contribution of this paper is in two parts. First, we present a framework for systematically managing the design process. Secondly, we illustrate how this framework can be used to manage a realistic system-level design environment that consists of a suite of sophisticated hardware and software design tools. We begin by identifying some of the desirable features of system-level design methodology management. A candidate framework that manifests these features is presented. Complex design flows with iterative and conditional behavior can be specified within the framework. The framework also supports automated scheduling of tools in a well-defined design flow. It has been implemented as the DMM domain in Ptolemy. In the second part of the paper, we describe a system-level design environment case study that we have developed within this framework. The environment, called the Design Assistant, is a complete hardware-software codesign environment. It encapsulates various codesign tools for specification, partitioning, and synthesis; their interplay can be managed efficiently by the design methodology management framework.

“…Previous languages have been restricted to describing lower level details, for example, the task specification language of Chiueh et al [2], which encapsulates tool details and provides for the sequencing of tasks but, unlike DDDL, doesn't describe the higher level details of a design discipline. Dewey [3] developed structures for representing properties and constraints in a design domain (in this case DSP filters) so as to support conceptual design. Again, information about decompositions, possible problems and methodologies necessary for managing the complete design process is missing.…”

A language for defining design discipline characteristics is proposed. Design discipline characteristics such as abstraction levels, design object classifications and decompositions, design objectives, and design methodologies can be defined in a simple machine and human readable form. The language, DDDL, has led to the development of a user interface for Minerva II, a design process management tool, which, when configured with a design discipline description, can be used to aid teams of designers in the solution of complex multi-disciplinary design problems. DDDL and user interface examples are presented.

“…Harjani, et al, [4] employs hardcoded plans for encoding multi-variable numerical optimization techniques in an analog circuit synthesis framework. These hardcoded plans are conceptually similar to complex CAD tasks (they statically encode a given design function), and therefore [4] also focuses on the design task level Dewey's conceptual design [5] work, developed to aid the designer in the decision making process that occurs during the early stages of the design process, is most closely related to the work described here. However, Dewey did not attempt to explicitly represent design problems or to map the set of design decisions developed during conceptual design into an actual executable design plan.…”

“…Conceptual design involves the investigation of alternative, often high level, design options in terms of their consequences on performance, without actually undertaking design and fabrication steps [5]. During this phase, designers may need assistance in the form of qualitative advice and/or quantitative information that can be used to discriminate among the various options.…”
