RTL Design Technique Using Libraries for GDI MOS and CMOS Mixed Mode Synthesis

We propose a novel register transfer level (RTL) design technique that applies both gate diffusion input (GDI) and CMOS process design kit (PDK). We create the GDI-CMOS PDK by merging the GDI synthesis library, which is made by extracting the characteristics of GDI cells, with the CMOS library. We synthesize a 16-bit RISC MCU sample circuit by applying the new RTL design technique, and compare and analyze a performance index, PPA. The proposed design technique can be applied as a new design flow by reducing the disadvantages of GDI and maximizing the advantages of area and power, thereby overcoming the disadvantages of CMOS circuits
