Power

I would suggest you to go through the topics in the sequence shown below –

1. Sources of power Dissipation in VLSI circuits
   • Static power
   • Dynamic power – switching power and short circuit power
2. Few common power management techniques
   • Multi V_th design
   • Bus encoding – Redundant and Non-redundant
   • Hardware software tradeoff
   • Multi V_dd design – SVS, DVFS
   • Clock gating
   • Power gating
3. Isolation cells and Level shifter cells used in multi-power domain and multi-voltage domain designs
   • Why do we need isolation cells and clamping concept in isolation
   • Why do we need retention cells and its types
4. Retention cells used in power gated domains.
   • Why do we need retention cell
   • Master/slave alive retention flop
5. Few important UPF command syntax.
   • create_power_switch
   • set_isolation
   • set_isolation_control
   • set_level_shifter
   • set_retention
   • set_retention_control
   • add_port_state
   • create_pst
   • add_pst_state
6. How to write UPF for a given power intent.
