Abstract

This paper presents a program named RLEXT (Register Level Exploration Tool), which allows a user to manually modify a register-level datapath design. The allowed operations are addition and deletion of components and connections. Any component not an i/o port, a register, or an addressable memory may be added or deleted. Any wire or connection of a pin to a wire may be added or deleted. The unique aspect of RLEXT is that the continued ability of the datapath to support its behavioral specifications is guaranteed: that is, if the user makes changes that would impair the datapath's ability to carry out the desired function, RLEXT will automatically repair the datapath so that it is once again able to express the specified behavior.
