Spezielle Anwendungen des VLSI – Entwurfs Applied VLSI design Course and contest Results of Phase 4 Nam Pham Van
Design comparison P ~ A Power: P = (Pdyn * Pleak) Area: A Reduction of the area lower the power consumption
Design & architecture • RCA small area low power consumption • Improve speed with Carry Skip architecture
Design & architecture optimization • Adder Reduction: • 10 bit 8 bit • 11 bit 10 bit • 16 bit 13 bit • Influences: • Minimized switch activity • Reduced area & power consumption
Cadenceconfiguration Setting Effect • Netlist optimization • Design optimization • Higher frequency are possible • Power consumption raised immense • Antenna fixing • Eco route • Wire optimization • No impact • Other gate libraries • Higher frequency are possible • Extreme high leakage power consumption
Cadenceconfiguration • Best settings: • Core Ratio H/W: 1 • Core Utilization: 90 • IO Boundary: 15 • Power Ring: • Width: 2 • Spacing: 0.5 • Offset: 2 • COREHVTtyp10V
