What is PVT in physical design?

PVT is abbreviation for Process, Voltage and Temperature. In order to make our chip to work in all possible conditions, like it should work in Siachen Glacier at -40°C and also in Sahara Desert at 60°C, we simulate it at different corners of process, voltage and temperature which IC may face after fabrication.

What is the physical design flow?

In integrated circuit design, physical design is a step in the standard design cycle which follows after the circuit design. These design flows lay down the process and guide-lines/framework for that phase. The physical design flow uses the technology libraries that are provided by the fabrication houses.

What is power planning in physical design?

Power planning means to provide power to the every macros, standard cells, and all other cells are present in the design. Power and Ground nets are usually laid out on the metal layers. In this create power and ground structure for both IO pads and core logic.

What is PVT analysis in VLSI?

PVT is the Process, Voltage, and Temperature. In order to make our chip to work after fabrication in all the possible conditions, we simulate it at different corners of process, voltage, and temperature. These conditions are called corners. All these three parameters directly affect the delay of the cell.

What is difference between placement and floorplanning?

floorplanning is about placing the macros and blockages and leaving the uniform space for the std cells and placement is about placing and legalizing the std cells.

What is timing corner in VLSI?

Each minima and maxima can be termed as a corner. Let us say, each minima/maxima in cell characteristics as ‘PVT corner’ and net characteristics as ‘extraction corner’. Each combination of PVT extraction corners is referred to as a ‘timing corner’ as it represents a point where timing will be extreme.
