CLSS-a workbench for control logic synthesis

Abstract

Describes a system called CLSS, that serves as a workbench for the synthesis of control logic. The system provides an integrated solution to the designer by providing effective solutions for all the major steps in the control logic synthesis flow. CLSS allows specification of the control logic in the form of a state transition representation. Through a set of transformation steps, all of which are an integral part of the CLSS workbench, the layout of the design is generated for standard cell or PLA based implementations. In addition to providing automated solutions to optimally perform state assignment, logic minimization, constrained area-delay optimization, etc., CLSS provides a mechanism for the expert designers to override the decisions taken by the system. The major strength of the system lies in the tight coupling between the several components of the flow in an integrated environment. Designed at Texas Instruments, the CLSS workbench has been successfully used on several large and realistic designs.<>
