Move treadle dependency to the tests (#1554)

2020-08-14T04:30:55+00:00

Use inheritance to make TesterDriver Backend API extensible, then define
a TreadleBackend in the test project

Using TreadleTesterPhase now requires new (#1520)

2020-07-25T22:42:14+00:00

Treadle tester phase requires new to fix problems found
when running tests in parallel.

Delete outdated scalastyle configuration comments from source

2020-07-21T20:06:53+00:00

- A few final fixes after the rebase

2020-06-29T17:44:13+00:00

This adds a mechanism for the unittests to be run with the TreadleBackend

2020-06-29T17:22:11+00:00

This mechanism is not enabled and should not change the behavior of existing tests
A following PR will deliver a switch that will allow changing the backend.
The reasons for this PR
- Treadle tests run much faster, enabling quicker debugging and CI cycles
- This will help ensure fidelity of Treadle to the Verilator backend

A few tests are marked as verilator only due to black box limitations

Change treadle to a direct dependency

I tried to make it a test only dependency but the TesterDriver sits in src/main requiring that
regular compile have access to treadle

Oops, made treadle the default

A number of changes in response to @ducky64 review
- made backend check clearer and add error handling for multiple backends specified
- Fixed duplicate TargetDirAnnotation uses in Treadle backend
- Cleaned up BlackBox test formatting
- Undid unnecessary debugging changes from Counter
- Undid .gitignore change, that should be on another PR

A number of changes in response to @ducky64 review
- Undid debugging changes made to BitWiseOps

Add missing finishWrapper call in TesterDriver (#1496)

Use ChiselStage in Tests

2020-06-23T00:00:10+00:00

This migrates the tests to Chisel 3.4/FIRRTL 1.4. This primarily
involves removing usages of deprecated methods including:

- Remove usages of Driver
- Use ChiselStage methods instead of BackendCompilationUtilities
  methods
- Use Dependency API for custom transforms
- Use extractCause to unpack StackError
