Abstract :
A description is given of new capabilities of the RLEXT register level exploration tool. RLEXT is an interactive tool that takes a datapath design and allows a user to modify it freely, using transformations that do not themselves preserve correctness. By maintaining a representation of the desired behavior and timing as well as structure, RLEXT is able to ´repair´ the design when the user creases modifying, so that the ability of the design to express the specified behavior is once again guaranteed. A description is also given of RLEXT´s support for manual changes of schedule in the presence of an existing data-path structure. Such schedule changes invalidate the structure, but the structure is incrementally repaired rather than just thrown out. The author knows of no other high-level synthesis tool that supports this kind of functionality.<>
