What are the i/p’s and o/p’s of power planning?
Power planning means making sure that all of the design’s macros, standard cells, and other cells have power. Here are the input and outputs for power planning,
Inputs
- Database with a valid floor plan.
- Power rings and power straps width.
- Spacing between Vdd and Vss straps.
Outputs
- Design with the power structure.
What are the i/p’s and o/p’s of placement?
The process of placing circuit devices on a die surface is known as placement. It is a important step in the VLSI design process since it influences a design’s performance, heat distribution, route ability, and, to a lesser extent, power consumption.
Inputs
- Netlist
- Design constraints.
- Mapped and floor planed design
- Logical and physical lib
Outputs
- Cell placement location.
- Physical layout information.
- Physical layout, timing, and technical information of lib.
