Results of Phase 3: ST65 Netlist

13.12.2012

Institute MD, University of Rostock

### Challenge

• Create a Verilog netlist for the ST65 technology

• Build upon NAND/NOR gatter

• 65 nm structure width

• Optimize design for the ST65 technology

• Change adder types for 10, 13 and 14 bit width

• Brent-Kung

• Ripple Carry

### Calculations Finals

Pdyn = 1 µW Pstat = 1 mW area = 3k VDD = 1,0 V

### Calculations Finals

Pdyn = 1 µW Pstat = 1 mW area = 6k VDD = 1,3 V

### Synopsys Flags

• Flags

• optimize_registers – move registers to decrease the negative slack

• set_ungroupyour_filter – unfold the hierarchical structures

• set_flatten true -design your_filter -effort high –minimize multiple_output-phase true

• set_structure true -design your_filter -boolean true -boolean_effort high -timing true

• set_max_area 3000 -ignore_tns

• set_max_leakage_power 1 mW

• set_max_dynamic_power 1 uW

• Compiling

• compile -map_effort high -power_effort high -ungroup_all -boundary_optimization–scan -auto_ungroupdelay

• compile_ultra -incremental -retime
