Power Intent of Large Designs
If the top design is large, the power intent extraction step might lead to memory-related issues. In such cases, follow the bottom-up approach, where you first extract the power intent of sub-blocks separately in 1801 files and then, associate the 1801 files with their respective instances in the top design. Consequently, when you extract power intent for the top design, the tool consumes less memory. Also, you can apply the bottom-up approach when extraction options cannot be shared between the top design and the sub-blocks. For example, when the power / ground nets definitions, power / ground net voltage definitions, or power net–ground net voltage pair definitions in the top design are different from the sub-block definitions, use the bottom-up approach.
