* Remove explicit import of NotStrict - fixes #492
* Provide macro for MemBase.apply().
* Provide macro for MemBase.apply().
Since a macro cannot override an abstract method, provide a concrete
apply method n VecLike() that we can override with a macro.
* Remove concrete apply() in VecLike.
Since MemBase no longer extends the trait VecLike, we do not require a concrete method to which we can apply a macro to extract the appropriate CompileOptions.
* Add missing implicit compileOptions to do_pad() and do_zext().
The latter caused:
```
[error] /vm/home/jenkins/workspace/rocket-chip_with_chisel3/hardfloat/src/main/scala/MulAddRecFN.scala:205: too many arguments for method do_zext: (implicit sourceInfo: chisel3.internal.sourceinfo.SourceInfo)chisel3.core.SInt
[error] val CDom_sExp = io.fromPreMul.sExpSum - io.fromPreMul.doSubMags.zext
```
* Add SourceInfoTransform macros to Vec methods in order to avoid apply() chain issues.
Since utils methods are no longer NotStrict, Pipe objects need access to the client's compile options. There may be more.
* Respond to review comments.
Don't propagate SourceInfo through helper functions.
Replace old usages of CompileOptionsTransform with the now equivalent SourceInfoTransform and redefine CompileOptionsTransform to only deal with CompileOptions.
Just thread CompileOptions (not SourceInfo) through deprecated functions.

Fixes #554
|
|
|
|
|
|
The old implementation failed to check for width <= -2, and
did the wrong thing when -1 was explicitly passed. Splitting
into two methods avoids the latter issue.
log2Ceil's argument might be 1, so employ a max operator.
|
|
Since the argument is at least 2, this change has no semantic effect.

|
|
Both should be zero-width wires.
|
|
Provide a better error message when length < 0.
Change log2Up in log2Ceil, which has no effect, since the argument
is always at least 2.
|
|
It always should throw an exception when n < 0, but in the specific
case of x.isWidthKnown && x.getWidth == 1, it failed to do so.
This commit also changes log2Up in log2Ceil, which has no effect,
since the argument is always at least 2.

* Move blackbox verilog implementations within reach of verilator
Blackbox implementers can annotate the modules with information on where to get the source verilog
This API is very lightweight, real work is done in firrtl in companion PR
Added some verilog to BlackBoxTest.v resource for testing
* if a file named black_box_verilog_files.f exists add a
-f black_box_verilog_files.f to the verilog to cpp command
|
|
* [stevo]: add reset initialization to shift register
* [stevo]: better comment
* [stevo]: add tests, fix bug

(#387)

Get rid of some cruft exposed in #373
This also allows Bits.fromtInt(...) to be removed. Yay!
All old APIs (with some new restrictions, rocket still works fine) are preserved without deprecation in Chisel._, aside from the non-compile-time-checkable Map[] enum constructor which probably should have been deprecated during chisel2. The Map[] enums have been removed from chisel3._ without deprecation.
The new restriction is that nodeType (legacy API) may only be of UInt type with unspecified width. Note that Bits() creates a UInt, and if you can't control the enum values, it makes little sense to specify a bitwidth.

Also, remove no-longer-special case for n=1.

Candidate fix for #245
|
|
This was originally mixed in with #199, Add Assert Data.
|
|
|
|
Massage CompileOption names in an attempt to preserve default (Strict) CompileOptions in the absence of explicit imports.
NOTE: Since the default is now strict, we may encounter errors when we generate connections for clients (i.e., in Vec.do_apply() when we wire up a sequence).
We should really thread the CompileOptions through the macro system so the client's implicits are used.
|
|
firrtlDirection should only be used for emitting firrtl. Any checks on the actual direction should use the bound Direction `dir`.
