1.6. Root Partition Reuse—Developer Tutorial
As a root partition Developer, you create, compile, and eventually export a top-level root partition that includes the device periphery. The Developer also reserves a core partition for subsequent development of core logic in the Consumer project.
The Developer fully compiles this design and then provides the root partition .qdb and an .sdc file for the top-level design.
The following figure shows the Developer's root partition with a placeholder for the blinking_led module. For this tutorial, blinking_led simply ties the outputs to 4’b1111 to turn off the LEDs.
