phases

Type Members

1. class AddImplicitOutputAnnotationFile extends Phase with PreservesAll[Phase]

   

   Adds an firrtl.options.OutputAnnotationFileAnnotation if one does not exist.

   Adds an firrtl.options.OutputAnnotationFileAnnotation if one does not exist. This replicates old behavior where an output annotation file was always written.

2. class AddImplicitOutputFile extends Phase with PreservesAll[Phase]

   

   Add a output file for a Chisel circuit, derived from the top module in the circuit, if no ChiselOutputFileAnnotation already exists.

3. class AspectPhase extends Phase

   

   Phase that consumes all Aspects and calls their toAnnotationSeq methods.

   Phase that consumes all Aspects and calls their toAnnotationSeq methods.

   Consumes the chisel3.stage.DesignAnnotation and converts every Aspect into their annotations prior to executing FIRRTL

4. class Checks extends Phase with PreservesAll[Phase]

   

   Sanity checks an firrtl.AnnotationSeq before running the main firrtl.options.Phases of chisel3.stage.ChiselStage.

5. class Convert extends Phase with PreservesAll[Phase]

   

   This prepares a ChiselCircuitAnnotation for compilation with FIRRTL.

   This prepares a ChiselCircuitAnnotation for compilation with FIRRTL. This does three things:

   • Uses chisel3.internal.firrtl.Converter to generate a FirrtlCircuitAnnotation
   • Extracts all firrtl.annotations.Annotations from the chisel3.internal.firrtl.Circuit
   • Generates any needed RunFirrtlTransformAnnotations from extracted firrtl.annotations.Annotations

6. class Elaborate extends Phase with PreservesAll[Phase]

   

   Elaborate all chisel3.stage.ChiselGeneratorAnnotations into chisel3.stage.ChiselCircuitAnnotations.

7. class Emitter extends Phase

   

   Emit a chisel3.stage.ChiselCircuitAnnotation to a file if a chisel3.stage.ChiselOutputFileAnnotation is present.

   Emit a chisel3.stage.ChiselCircuitAnnotation to a file if a chisel3.stage.ChiselOutputFileAnnotation is present. A deleted firrtl.EmittedFirrtlCircuitAnnotation is added.

   To do

   The use of the deleted firrtl.EmittedFirrtlCircuitAnnotation is a kludge to provide some breadcrumbs such that the emitted CHIRRTL can be provided back to the old Driver. This should be removed or a better solution developed.

   ,

   This should be switched to support correct emission of multiple circuits to multiple files. The API should likely mirror how the firrtl.stage.phases.Compiler parses annotations into "global" annotations and left-associative per-circuit annotations.

8. class MaybeAspectPhase extends Phase with PreservesAll[Phase]

   

   Run AspectPhase if a chisel3.aop.Aspect is present.

9. class MaybeFirrtlStage extends Phase with PreservesAll[Phase]

   

   Run firrtl.stage.FirrtlStage if a chisel3.stage.NoRunFirrtlCompilerAnnotation is not present.
