Server Side C-DASH: Ubiquitous Hardware/Software Codesign Environment

We have developed a processor development environment C-DASH (C-like Design Automation Shell). C-DASH generates HW (Hardware) and SWDE (Software Development Environment) from a processor definition file. To use C-DASH, each user must install C-DASH into local PC. When developing a processor as a team there is often a problem of file consistency, such as when another developer changes the same files you have. To solve this problem a collaborative development environment is required. This paper describes the implementation of a server side ubiquitous codesign environment for an ISA simulator. A server side codesign environment makes it unnecessary to install C-DASH onto local hosts, and makes codesign environment into device independent, and collaborative development becomes easier. A developer can upload a processor definition file via a web browser and develop an ISA (Instruction Set Architecture) simulator.
