Logic Synthesis and Place-and-Route Environment for ORGAs

We have continued development of Optically Reconfigurable Gate Arrays (ORGAs) to realize larger virtual gate count VLSIs than currently available VLSIs. The grain and structure of ORGAs must be changed depending on their dynamically reconfigurable applications. Therefore, an ORGA development tool must be easily customizable for changes of the grain and structure. This paper presents an easily-customizable logic synthesis, and a place-and-route environment of ORGAs using appropriate software tools (Design Compiler and Apollo; Synopsys Inc.).
