A Component-Based Design Environment for ESL Design

An electronic system-level (ESL) design flow based on Gezel language, which supports abstraction and reuse, is presented. Gazel consists of a simple but extendable hardware description language (HDL) and an extensible simulation-and refinement kernel, these components can be processor models or hardware simulation kernels. A common definition for ESL design is the collection of design techniques for selecting and refining an architecture, but ESL design has many aspects and forms. Even within a single application domain, system-level design can show wide variations which are difficult to capture with universal design languages and architectures. A port of the Java-embedded virtual machine, the SH3-DSP ISS, and the Gezel kernel are integrated for an ESL design, this design, in addition, required a considerable number of cryptographic support libraries. This kind of design demonstrates the importance of varying the design abstraction level within a single platform.status: publishe
