2022-10-17Add opt-in AutoCloneType for Records (backport #2781) (#2785)mergify[bot]
* Add opt-in AutoCloneType for Records (#2781) There is a new trait, chisel3.experimental.AutoCloneType that is mixed in to Bundle and can optionally be mixed in to user-defined Records. The compiler plugin prints a deprecation warning on any user-defined implementation of cloneType, telling the user to mix in AutoCloneType before upgrading to 3.6.

2022-08-16Add OpaqueType support to Records (backport #2662) (#2679)mergify[bot]
* Add OpaqueType support to Records (#2662) OpaqueTypes are essentially type aliases that hide the underlying type. They are implemented in Chisel as Records of a single, unnamed element where the wrapping Record does not exist in the emitted FIRRTL.

2022-07-30Remove chiseltest from defaultVersions (#2651)Jack Koenig
Release automation tries to bump chiseltest which causes issues due to SBT trying to resolve all dependencies (even for projects that will not be published, like integrationTests).

2022-06-23Publish unidoc as ScalaDoc in chisel project (backport #2595) (#2598)mergify[bot]
* Publish unidoc as ScalaDoc in chisel project (#2595) This makes it such that we can stop hosting ScalaDoc on the Chisel website, instead just pointing to the latest docs on javadoc.io (cherry picked from commit 8b9f3d78ea23d9d9f0a118d1a2c30478ca2ff2f9) # Conflicts: # build.sbt * Resolve backport conflicts Co-authored-by: Jack Koenig <koenig@sifive.com> Co-authored-by: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com>
2022-06-16Define leading '_' as API for creating temporaries (backport #2580) (#2581)mergify[bot]
* Define leading '_' as API for creating temporaries Chisel and FIRRTL have long used signals with names beginning with an underscore as an API to specify that the name does not really matter. Tools like Verilator follow a similar convention and exclude signals with underscore names from waveform dumps by default. With the introduction of compiler-plugin prefixing in Chisel 3.4, the convention remained but was hard for users to use unless the unnnamed signal existed outside of any prefix domain. Notably, unnamed signals are most useful when creating wires inside of utility methods which almost always results in the signal ending up with a prefix. With this commit, Chisel explicitly recognizes signals whos val names start with an underscore and preserve that underscore regardless of any prefixing. Chisel will also ignore such underscores when generating prefixes based on the temporary signal, preventing accidental double underscores in the names of signals that are prefixed by the temporary. (cherry picked from commit bd94366290886f3489d58f88b9768c7c11fa2cb6) * Remove unused defaultPrefix argument from _computeName (cherry picked from commit ec178aa20a830df2c8c756b9e569709a59073554) # Conflicts: # core/src/main/scala/chisel3/Module.scala # core/src/main/scala/chisel3/experimental/hierarchy/ModuleClone.scala * Resolve backport conflicts * Waive false positive binary compatibility errors Co-authored-by: Jack Koenig <koenig@sifive.com>

2022-02-01Improve error reporting (backport #2376) (#2379)mergify[bot]
* Improve error reporting (#2376) * Do not trim stack traces of exceptions with no stack trace This prevents us from accidentally giving stack traces to exceptions that don't have them and giving misleading messages telling users to use --full-stacktrace when it won't actually do anything. Also deprecate ChiselException.chiselStackTrace which is no longer being used anywhere in this codebase. * Add exception class for multiple-errors reported New chisel3.internal.Errors replaces old anonymous class that would show up as chisel3.internal.ErrorLog$$anon$1 in error messages. * Add new option --throw-on-first-error This tells Chisel not to aggregate recoverable errors but instead to throw an exception on the first one. This gives a stack trace for users who need it for debugging. (cherry picked from commit ff2e9c92247b3848659fa09fdd53ddde2120036a) * Waive MiMa false positives The waived change is to a package private constructor.

2021-08-12Add DataView (#1955)Jack Koenig
DataView is a mechanism for "viewing" Scala objects as a subtype of `Data`. Often, this is useful for viewing one subtype of `Data`, as another. One can think about a DataView as a cross between a customizable cast and an untagged union. A DataView has a Target type `T`, and a View type `V`. DataView requires that an implementation of `DataProduct` is available for Target types. DataProduct is a type class that provides a way to iterate on `Data` children of objects of implementing types. If a DataView is provided for a type T to a type V, then the function .viewAs[V] (of type T => V) is available. The object (of type T) returned by .viewAs is called a "View" and can be used as both an rvalue and an lvalue. Unlike when using an .asTypeOf cast, connecting to a "View" will connect to the associated field or fields of the underlying Target. DataView also enables .viewAsSupertype which is available for viewing Bundles as a parent Bundle type. It is similar to .viewAs but requires a prototype object of the Target type which will be cloned in order to create the returned View. .viewAsSupertype maps between the corresponding fields of the parent and child Bundle types.

MiMa binary compatibility checks are now run on master, but the mimaPreviousArtifacts are empty which makes the check a no-op.

2020-09-04Better Building of FIRRTL From Source (#1563)Jack Koenig
Using JVM system properties sbt.sourcemode and sbt.workspace, one can now easily build chisel3 with firrtl from source Example use: Assuming firrtl is cloned into the chisel3 root directory: $ sbt -Dsbt.sourcemode=true -Dsbt.workspace=$PWD Alternatively, one can set these properties in .sbtopts which can then be committed, enabling building from source by default
