如何将过时的low Firrtl转换为依赖项API

Question

我正在更新一个Firrtl转换，如下所示

class RetimeTransform extends Transform {
  override def inputForm: CircuitForm = LowForm
  override def outputForm: CircuitForm = LowForm
  
  ...

添加到新的依赖项API。将转换更改为以下内容

class RetimeTransform extends Transform with DependencyAPIMigration {

但现在它不会像以前那样按相同的顺序运行转换。有没有一种简单的方法来指定依赖关系，这样我就可以得到原始的行为？

非常感谢Chisel团队。似乎答案是这样进行转换。

class RetimeTransform extends Transform with DependencyAPIMigration {

  override def prerequisites: Seq[TransformDependency] = Forms.LowForm
  override def optionalPrerequisites: Seq[TransformDependency] = Forms.LowFormOptimized
  override def optionalPrerequisiteOf: Seq[TransformDependency] = Forms.LowEmitters
