optionalPrerequisiteOf: Seq[Dependency[Transform]]
A sequence of transforms to add this transform as an
optionalPrerequisite.A sequence of transforms to add this transform as an
optionalPrerequisite. The use ofoptionalPrerequisiteOfenables the transform declaring them to always run before some other transforms. However, declaringoptionalPrerequisiteOfwill not result in the sequence of transforms executing.This is useful for providing an ordering constraint to guarantee that other transforms (e.g., emitters) will not be scheduled before you.

This method **will not** result in the listed transforms running. If you want to add multiple transforms at once, you should use a
DependencyManagerwith multiple targets.

dependents: Seq[Dependency[Transform]]

All transforms that must run after this transform
This is a means of prerequisite injection into some other transform. Normally a transform will define its own prerequisites. Dependents exist for two main situations:
First, they improve the composition of optional transforms. If some first transform is optional (e.g., an expensive validation check), you would like to be able to conditionally cause it to run. If it is listed as a prerequisite on some other, second transform then it must always run before that second transform. There's no way to turn it off. However, by listing the second transform as a dependent of the first transform, the first transform will only run (and be treated as a prerequisite of the second transform) if included in a list of target transforms that should be run.
Second, an external library would like to inject some first transform before a second transform inside FIRRTL. In this situation, the second transform cannot have any knowledge of external libraries. The use of a dependent here allows for prerequisite injection into FIRRTL proper.

(Since version FIRRTL 1.3) Due to confusion, 'dependents' is being renamed to 'optionalPrerequisiteOf'. Override the latter instead.
