IC design PD corner definition

In IC (Integrated Circuit) design, PD (Power Distribution) corner refers to a specific set of conditions that are used to test the functionality of the power distribution network within the integrated circuit. The PD corner defines the worst-case scenario for power consumption and voltage drop across the IC, ensuring that the power distribution network can handle the maximum power consumption and maintain stable voltage levels under all operating conditions.

The PD corner is typically defined by specifying the maximum and minimum values for various parameters, such as the supply voltage, operating frequency, temperature, and process variations. The corner analysis is performed by simulating the circuit under these extreme conditions to ensure that the power distribution network is robust enough to handle any potential power or voltage fluctuations.

The PD corner analysis is an essential part of the IC design process as it helps to ensure that the integrated circuit will function correctly under all operating conditions, minimizing the risk of failure due to power-related issues.
