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).

2021-07-01Add ChiselEnum.safe factory method and avoid warningJack Koenig
Previously, ChiselEnum would warn any time a UInt is converted to an Enum. There was no way to suppress this warning. Now there is a factory method (`.safe`) that does not warn and returns (Enum, Bool) where the Bool is the result of calling .isValid on an Enum object. The regular UInt cast is also now smarter and will not warn if all bitvectors of the width of the Enum are legal states.

2021-06-29Change behavior of aop.Select to not include CloneModuleAsRecordJack Koenig
Previously, CloneModuleAsRecord clones would result in the same BaseModule object coming up multiple times when using APIs like .instances, .collectDeep, and .getDeep. This was not the intended behavior and can lead to very subtle bugs.

2021-06-10Stop Emitting BlackBoxResourceAnno (#1954)Schuyler Eldridge
* Change HasBlackBoxResource to Resolve Resources Change HasBlackBoxResource to resolve resources immediately and emit BlackBoxInlineAnno instead of a BlackBoxResourceAnno. This removes the need for a FIRRTL compiler to grok the Java Resource API in order to handle BlackBoxResourceAnno. Emit BlackBoxInlineAnno from HasExtModuleResource instead of BlackBoxResourceAnno.

2021-05-09Fix ShiftRegister with 0 delay. (#1903)Jiuyang Liu
* Add test to check ShiftRegister(s) with delay is 0. This should break ShiftRegister(x, 0) since last is not exist in a empty Seq. Originally, test only test 1 to 4, which missed a potential bug from #1723. * Fix ShiftRegister with 0 delay. if ShiftRegisters is empty, java will complain: ``` java.util.NoSuchElementException scala.collection.LinearSeqOptimized.last(LinearSeqOptimized.scala:150) ``` This fix this issue and return `in` directly when ShiftRegister size is 0.

2021-04-27Introduce VecLiterals (#1834)Chick Markley
This PR provides for support for Vec literals. They can be one of two forms Inferred: ``` Vec.Lit(0x1.U, 0x2.U) ``` or explicit: ``` Vec(2, UInt(4.W)).Lit(0 -> 0x1.U, 1 -> 0x2.U) ``` - Explicit form allows for partial, or sparse, literals. - Vec literals can be used as Register initializers - Arbitrary nesting (consistent with type constraints is allowed)

2021-02-11Fix stack trace trimming across Driver/ChiselStage (#1771)Schuyler Eldridge
* Handle MemTypeBinding in Analog Signed-off-by: Schuyler Eldridge <schuyler.eldridge@sifive.com> * Fix stack trace trimming across ChiselStage Fix bug in stack trace trimming behavior. Now, the following is what happens: 1. The Builder, if catching accumulated errors, will now throw a ChiselException with a Scala-trimmed Stack trace. Previously, this would throw the full excpetion. 2. The Elaborate phase handles stack trace trimming. By default, any Throwable thrown during elaboration will have its stack trace *mutably* trimmed and is rethrown. A logger.error is printed stating that there was an error during elaboration and how the user can turn on the full stack trace. If the --full-stacktrace option is on, then the Throwable is not caught and only the first logger.error (saying that elaboration failed) will be printed. 3. ChiselStage (the class), ChiselStage$ (the object), and ChiselMain all inherit the behavior of (2). Mutable stack trace trimming behavior is moved into an implicit class (previously this was defined on ChiselException only) so this can be applied to any Throwable. No StageErrors are now thrown anymore. However, StageErrors may still be caught by ChiselMain (since it is a StageMain). Testing is added for ChiselMain, ChiselStage, and ChiselStage$ to test all this behavior. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@sifive.com>
2021-02-09Make it possible to GC Data instancesJack Koenig
No longer create a pointer from parent to every HasId, only do it by default for BaseModules and MemBases. Add pointer from parent to Data upon binding the Data. * Add MemTypeBinding for port types of Mems This binding is similar to the SampleElementBinding for Vecs in that these Data are not truly hardware, but are represented in the FIRRTL IR and thus need some representation. * Call _onModuleClose on unbound Records This maintains some corner-case behavior that is nevertheless relied upon. It ensures that refs are set for the elements of Records, even if they are not bound to any real hardware.
