- Qualifying libraries, existing netlist and design constraints

- Clock tree generation and optimization

- Power planning and optimization

- Full-chip extraction

- Full-chip physical verification

- Formal verification

- Chip finishing to tapeout


Low-Power Implementation

Leakage Power Reduction

    Power Shut Off (PSO): Coarse grain power gating insertion and spice level rush current analysis;

                                      Solation cell insertion and verification;

                                      State retention register replacement.

    Multi-VT:  multi-VT libraries optimization maximizes low leakage cells replacement.


Dynamic Power Reduction

Low-Power CTS: 
Optimized clock gating insertion; 
                          Minimized clock tree depth and optimization transition control.

Multiple Supply Voltage(MSV): Level-shifter insertion between power islands.

Dynamic Voltage Frequency Scaling (DVFS):
Accurate power mode verification;
                                                                   Dynamic clock tree balancing;    

                                                                   Cross-domain logic synchronization.
