- Create `TywavesAnnotation` (firrtl) case class to represent the annotation
- Add companion object to generate `TywavesChiselAnnotation`s for Chisel circuit: it parses a chisel circuit, extracts the necessary information from each component, and annotates each FIRRTL target
- Support annotation for IO ports
- Add support for modules and data types (grounds, aggregates, and user-defined (only extended bundles))
- Support nested modules and data types
- Create `AddTywavesAnnotations` phase to add the TywavesAnnotation to the elaborated Chisel circuit
- Update `ChiselStage` to integrate `AddTywavesAnnotation` phase (run before `Convert` phase only if `withDebug` is true)
- Added following tests:
- Module tests:
- Empty module
- Module with submodule(s)
- Modules with parameters and paremetrized modules (need to extract scala meta-programming information though)
- BlackBoxes
- Intrinsics
- Classes
- Ports test:
- Explict Clock, SyncReset (Bool), AsyncReset and Reset
- Implicit clock and reset
- Ground types: Bool, UInt, SInt, Analog
- Bundles: empty, anonymous, user-defined, nested
- Vecs: 1-D, 2-D
- MixedVec
- Vecs of bundles
- Bundles of vecs
- Added "createAnno" from DefWire, DefRef, DefRegInit case
- Reorganize test structure making reusable modules for different bindings (IO, Reg, Wire)
- Added following tests:
- Ports tests:
- Ports inside a submodule
- Wire/reg tests:
- Explict Clock, SyncReset (Bool), AsyncReset and Reset
- Implicit clock and reset
- Ground types: Bool, UInt, SInt
- Analog (only wires)
- Bundles: empty, anonymous, user-defined, nested
- Vecs: 1-D, 2-D
- MixedVec
- Vecs of bundles
- Bundles of vecs
- Wires/regs inside a submodule
- Move module and data types tests in different subdirectories - Add readmes with output samples of the annotations
- Added "createAnno" from DefMemory, DefSeqMemory, FirrtlMemory and DefMemPort case
- Implement "createAnnoMem" to create a TyeavesAnnotation for memory (a memory does not extend the Data type)
- Return empty annotations from Connect, DefInvalid
- Add warning message for "Unhandled circuit commands"
- Added the following tests:
- ROM of ground type
- SyncReadMem (when UNUSED) of ground type, aggregate types (bundle)
- Mem (when UNUSED) of ground type, aggregate types (bundle)
- SRAM of ground type (with different combs of ports), aggregate types
- SyncReadMem (when USED) of ground type, aggregate types (this instantiate MPORT)
- Mem (when USED) of ground type, aggregate types (this instantiate MPORT)
…of Vecs) - Added the following tests: - Masked memories (SyncReadMem, Mem, SRAM)
…onstructor (it works for any scala class)
[Fix tywaves] Fix annotation issue for first parameter of the constructor
Sometimes the first parameters was skipped. The `getConstructorParams` was dropping the first element of the list assuming that it contained the class itself and not a parameter.
This assumption worked only for some cases ("$outer" is not always present in first position). Now the method is improved by doing a filter map (collect).
Update report output samples in tests readmes
Annotate types with parameters in the scala constructor (it works for any scala class)
- Create a case class (`ClassParam`) to represent the parameters of a class in the firrtl annotation
- Update `TywavesAnnotation` with `params: Option[Seq[ClassParam]]`. Some classes may not have any parameter
- Implement `getConstructorParams()` to get params of a constructor of any scala class. It uses scala reflection.
- Added the following tests:
- Test getConstructorParams() for:
- classes
- case classes
- private, protected and public fields in the constructor: name, type and value accessible
- fields in the body of a class (expected behaviour not accessible)
- parameters in the constructor (no val): only name and type accessible
- Updated the following tests:
- Vec tests of DataTypesSpec: chisel Vecs have a length parameter in the constructor
- Mem tests: memories contain constructs with parameters in their constructors
- Module tests: update the module with parameters test
…s type of chisel3.Data
Now it returns only the value without the complete name (packageName.type.name) of the parameter.
- Fix hasParams: sometimes some parameters of a class were not detected.
- Added the following tests:
- Circuit with parameters (scala basic types, scala classes, and chisel types)
- Bundles with parameters (scala basic types, scala classes, and chisel types)
- Updated tests (scala fmt and bug fix):
- TypeAnnotationMemSpec
- TypeAnnotationModuleSpec
- TypeAnnotationDataTypesSpec
- Fix scalafmt errors

This is a first attempt for generating and propagating scala source language type information to CIRCT #4015.
This PR adds a new option to support the new backend of my project: a type-based waveform viewer. Chisel currently misses an open-source waveform viewer and tywaves is adding support for Chisel to Surfer.
I wrote more details about the internal changes here: https://github.com/rameloni/tywaves-chisel-demo/wiki/Changes-in-Chisel.
While the full wiki contains also details about the integration of the different components involved.
