Asynchronous Wrapper for Globally Asynchronous Locally Synchronous Systems

Abstract: This thesis is investigating the new globally asynchronous locally synchronous (GALS) technology for integrated circuits. Different types of asynchronous wrappers are tested and a new wrapper design is presented. It also investigates the possibility to use VHDL for asynchronous simulation and synthesis. The conclusions are that the GALS technology is possible to use but that it needs new synthesis tools, because todays tools are designed for synchronous technology.
