1.5. Module 3: Optimize with Fast Preservation

Follow the steps in this tutorial module to enable the Fast Preserve option during design optimization.

Process Description

You can create a separate revision of your project that reuses the preserved root partition during optimization of the other partitions. When you enable the Fast Preserve option, the Compiler reduces the logic of the imported partition to only the interface logic between the partition boundary and the rest of the design, thereby reducing the compilation time the partition requires.

In this tutorial module, you reuse the root partition, which is the partition that includes the device periphery.
