Deprecated Type Members

1.  class BareShell extends AnyRef

   A utility for working with command line options.

   A utility for working with command line options. This provides no options by default other than "--help". This is intended for lower-level APIs which do not want to include options that are provided by Shell.

2.  trait BufferedCustomFileEmission extends CustomFileEmission

   A buffered version of CustomFileEmission

   A buffered version of CustomFileEmission

   This is especially useful for serializing large data structures. When emitting Strings, it makes it much easier to avoid materializing the entire serialized String in memory. It also helps avoid materializing intermediate datastructures in memory. Finally, it reduces iteration overhead and helps optimize I/O performance.

   It may seem strange to use Array[Byte] in an otherwise immutable API, but for maximal performance it is best to use the JVM primitive that file I/O uses. These Arrays should only used immutably even though the Java API technically does allow mutating them.

3.  trait CustomFileEmission extends AnyRef

   Mix-in that lets an Annotation serialize itself to a file separate from the output annotation file.

   Mix-in that lets an Annotation serialize itself to a file separate from the output annotation file.

   This can be used as a mechanism to serialize an Unserializable annotation or to write ancillary collateral used by downstream tooling, e.g., a TCL script or an FPGA constraints file. Any annotations using this mix-in will be serialized by the WriteOutputAnnotations phase. This is one of the last phases common to all Stages and should not have to be called/included manually.

   Note: from the perspective of transforms generating annotations that mix-in this trait, the serialized files are not expected to be available to downstream transforms. Communication of information between transforms must occur through the annotations that will eventually be serialized to files.

5.  trait DependencyAPI[A <: DependencyAPI[A]] extends AnyRef

   Mixin that defines dependencies between TransformLikes (hereafter referred to as "transforms")

   Mixin that defines dependencies between TransformLikes (hereafter referred to as "transforms")

   This trait forms the basis of the Dependency API of the Chisel/FIRRTL Hardware Compiler Framework. Dependencies are defined in terms of prerequisistes, optional prerequisites, optional prerequisites of, and invalidates. A prerequisite is a transform that must run before this transform. An optional prerequisites is transform that should run before this transform if the other transform is a target (or the prerequisite of a target). An optional prerequisite of is an optional prerequisite injected into another transform. Finally, invalidates define the set of transforms whose effects this transform undos/invalidates. (Invalidation then implies that a transform that is invalidated by this transform and needed by another transform will need to be re-run.)

   This Dependency API only defines dependencies. A concrete DependencyManager is expected to be used to statically resolve a linear ordering of transforms that satisfies dependency requirements.
