2021-12-02Refactor Data.toString (#2197)Aditya Naik
Provides a more intuitive implementation of toString for Data. Utilizes the fact that the compiler plugin provides names earlier than Chisel had in the past so we can accurately guess the name of signals even in the currently elaborating module.

2021-10-05Fix naming of unwrapped val io in Chisel.Modules (#2150)Jack Koenig
The removal of virtual method io accidentally made the naming of io in compatibility mode Bundles sensitive to the prefix at the time of the first access of the field. It also made .suggestName able to override the name. This commit fixes that issue by forcing the name of the io Data to be "io" no matter what.

2021-09-05Add Definition and Instance API (#2045)Adam Izraelevitz
This introduces a new experimental API for module instantiation that disentagles elaborating the definition (or implementation) from instantiation of a given module. This solves Chisel's longstanding reliance on "Deduplication" for generating Verilog with multiple instances of the same module. The new API resides in package chisel3.experimental.hierarchy. Please see the hierarchy ScalaDoc, documentation, and tests for examples of use.

2021-08-31Fix chisel3 <> for compatibility Bundles (Take 3) (#2093)Jack Koenig
Previous incomplete fixes in #2023 and #2031. The legality of a FIRRTL connection is determined by type and flow. Chisel does not have access to true flow information. Previous fix attempts tried to use ActualDirection as a stand-in for flow, but it is incorrect in many cases. This new approach checks the flows of the lvalue and rvalues in the connect and flips the connection if either the lvalue cannot be a sink or the rvalue cannot be a source.

* replace custom model checker with chiseltest formal verify command * integration-tests can make use of chiseltest This is a compromise solution to avoid issues with binary compatibility breaking changes in chisel3. * ci: move integration tests into separate job * run integration tests only for one scala version * ci: install espresso for integration tests * Update build.sbt Co-authored-by: Jack Koenig <jack.koenig3@gmail.com> Co-authored-by: Jack Koenig <jack.koenig3@gmail.com>
2021-08-23Remove chisel3's own firrtl Emitter, use firrtl SerializerJack Koenig
This will be slightly slower as it involves converting from Chisel modules to FIRRTL modules before turning them into Strings. This cost is somewhat mitigated by doing that conversion lazily such that we never materialize the entire firrtl Circuit in memory, only 1 module at a time.
2021-08-23Add multiple dimensions to VecInit fill and iterate (#2065)anniej-sifive
Co-authored-by: Jack Koenig <koenig@sifive.com>
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.

2021-07-09Fix chisel3 <> for Bundles that contain compatibility Bundles (Take 2) (#2031)Jack Koenig
PR #2023 fixed a composition issue for chisel3 biconnects delegating to FIRRTL partial connect when compatibility mode Bundles are elements of chisel3 Bundles. It missed an important case though that caused previously working code to break. The bug is fixed by doing the automatic flipping for compatibility mode Bundles that have "Input" as a direction in addition to those that are "Flipped".
2021-07-08Make it legal for concrete resets to drive abstract reset (#2018)Jack Koenig
This has been legal in FIRRTL since v1.2.3 (when reset inference started using a unification-style algorithm) but was never exposed in the Chisel API. Also delete the overridden connects in AsyncReset and ResetType which just duplicate logic from MonoConnect.
2021-07-08Fix chisel3 <> for Bundles that contain compatibility Bundles (#2023)Jack Koenig
BiConnect in chisel3 delegates to FIRRTL <- semantics whenever it hits a Bundle defined in `import Chisel._`. Because chisel3 <> is commutative it needs to be mindful of flippedness when emitting a FIRRTL <- (which is *not* commutative).
