2019-04-12Implement connectFromBits in ChiselEnum (#1052)Jack Koenig
This is necessary to use ChiselEnum in aggregates where things are casted using .asTypeOf
2019-04-01Detect bundle aliasing (#1050)Richard Lin
2019-03-29Ignore empty aggregates elements when binding aggregate direction (#946)Jack Koenig
Previously, including an empty aggregate in a Bundle would cause a MixedDirectionAggregateException because it has no elements and thus doesn't have a direction * Add SampleElementBinding for Vec sample elements * Add ActualDirection.Empty for bound empty aggregates
2019-03-28Make core.DontCare private to chisel3 (#1054)Jim Lawson
Force clients to access 'DontCare' through the chisel3 package to ensure it's created as a chisel3 object and not a client object.

2019-03-22Fix enum annotations (#936)Hasan Genc
* Turned off strong enum annotations because they weren't working with Vec indexes * Add new EnumVecAnnotation for vecs of enums and vecs of bundles with enum fields * Changed Clock's width parameter back to a fixed constant value of 1 * Fixed enum annotations for Vecs of Bundles which contain enum elements * Fixed usage of "when/otherwise" to use consistent style
2019-03-21Change == to reference equality (eq) in Data print (#1044)Richard Lin
2019-03-18Split #974 into two PRs - scalastyle updates (#1037)Jim Lawson
* Update style warnings now that subprojects are aggregated. Use "scalastyle-test-config.xml" for scalastyle config in tests. Enable "_" in method names and accept method names ending in "_=". Re-sync scalastyle-test-config.xml with scalastyle-config.xml * Remove bogus tests that crept in with git add * Add missing import.
2019-03-15Fix PopCount widthAndrew Waterman
2019-01-25WireDefault instead of WireInit, keep WireInit around (#986)Martin Schoeberl
2019-01-22Import aliases for chisel3.core (#998)Richard Lin
Compatibility for rename introduced by #994
2019-01-22Define Data .toString (#985)Richard Lin
toString on Data subtypes will now print the type and optionally binding information including literals and IO names as feasible.
2019-01-22Add Rocket Chip-style clonemodule as CloneModuleAsRecord to experimental (#943)Albert Magyar
2019-01-21Support DontCare in Mux and cloneSupertype (#995)Richard Lin
2019-01-21Unify internal (chisel3.core) and external (chisel3 / chisel3.experimental) ↵Richard Lin
Module class names (#994)
2019-01-17Unary_- is truncatingAndrew Waterman
2019-01-17Make combinational-multiplier warning less vagueAndrew Waterman
2019-01-17Improve description of UInt.asSIntAndrew Waterman
2019-01-17Fix width-inference description of Bits.<<Andrew Waterman
2019-01-17Fix scaladoc for UInt.unary_!Andrew Waterman
It performs the operation (x === 0.U), just like in C. The scaladoc incorrectly described it as performing the operation !x(0). (Obviously, these are equivalent for Bool, but not for UInt in general).
2019-01-17Merge branch 'master' into improve-andrSchuyler Eldridge
2019-01-17Generate better code for UInt.andRAndrew Waterman
In the case that the width is known, we can emit one fewer Firrtl node. This obviously synthesizes the same way, but compiles/simulates faster.
2019-01-11For chiselName, use nameRecursively rather than matching on HasIdAndrew Waterman
2019-01-11Move nameRecursively into Builder so it can be used elsewhereAndrew Waterman
2018-12-19Fix width inferencing issue (#952)Jack Koenig
* Fix width propagation of non-literals in WireInit and RegInit * Change .getWidth to throw an exception instead of calling .get * Add utilities for checking inferred vs. known widths * Add tests for Wire, WireInit, Reg, and RegInit width inference * Add ScalaDoc for Reg, Wire, RegInit, and WireInit
2018-12-11Emit UInt.-% as tail(sub(x,y),1), not tail(asUInt(sub(x,y)),1)Andrew Waterman
This is semantically equivalent, but gets rid of a bunch of Firrtl text. It also gets rid of a bunch of Verilog, because Firrtl is capable of pattern-matching the new expression into SubWrap. The effect is that we now get wire [4:0] in; wire [4:0] res; assign res = 5'h0 - in; instead of wire [4:0] in; wire [5:0] _T_40; wire [5:0] _T_41; wire [4:0] res; assign _T_40 = 5'h0 - in; assign _T_41 = $unsigned(_T_40); assign res = _T_41[4:0];
2018-12-04Add asBool, deprecate toBoolJack Koenig
2018-12-04Add asBools, deprecate toBoolsJack Koenig
2018-12-04Make toBools support chained applyJack Koenig
The expanded version substituted in by the macro was misspelled, renamed from toBools -> do_toBools as expected by the macro
2018-11-26Trim Stack Trace (#931)Albert Chen
- Trim stack trace to show better, reduced information to the user - Add --full-stacktrace to FIRRTL option to show full stack trace
2018-11-20Make Vec cloneType keep directions of elements (#945)Jack Koenig
Fixes #893
2018-11-01Add BigInt / Int to Bool conversion (0.B, 1.B) (#913)Richard Lin
2018-10-29Turn off strong enum annotations (#916)Hasan Genc
* Turned off strong enum annotations because they weren't working with Vec indexes * Ignore annotation tests using ScalaTest's 'ignore', rather than by commenting them out
2018-10-25Check BaseModule.name for NullPointerExceptionSchuyler Eldridge
This wraps the evaluation of BaseModule.name in try/catch to look for a NullPointerException that may result from trying to evaluate desiredName before it's ready. This catches a test case of using a desiredName that depends on a later defined eager subinstance. h/t @jackkoenig Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>
2018-10-25Make BaseModule.name lazySchuyler Eldridge
This changes BaseModule.name to be lazy (instead of eager) to enable a desiredName to be a function of a sub-instance. This includes a test case showing the new behavior. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>
2018-10-12Strong enums (#892)Hasan Genc
* Added new strongly-typed enum construct called "StrongEnum". "StrongEnum" will automatically generate annotations that HDL backends can use to mark components as enums Removed "override val width" constructor parameter from "Element" so that classes with variable widths, like the new strong enums, can inherit from it Changed the parameter types of certain functions, such as "switch", "is", and "LitArg.bindLitArg" from "Bits" to "Element", so that they can take the new strong enums as arguments * Added tests for the new strong enums * Changed StrongEnum exception names and made sure in StrongEnum tests that the correct types of exceptions are thrown * Fixed bug where an enum's global annotation would not be set if it was used in multiple circuits Made styling changes to StrongEnum.scala * Reverted accidental changes to the AnnotatingDiamond test * Changed the API for casting non-literal UInts to enums Added an isValid function that checks whether or not enums have valid values Calling getWidth on an enum's companion object now returns a BigInt instead of an Int * Casting a literal to an enum using the StrongEnum.castFromNonLit(n) function is now simply a wrapper for StrongEnum.apply(n) * Fixed compilation bug * * Added "next" method to EnumType * Renamed "castFromNonLit" to "fromBits" * The FSM example in the test/scala/cookbook now uses StrongEnums * * Changed strong enum API, so that users no longer have to declare both a class and a companion object for each strong enum * Strong enums do not have to be static any longer * * Added scope protections to ChiselEnum.Value so that users cannot call it outside of a ChiselEnum definition * Renamed ChiselEnum.Value type to ChiselEnum.Type so that we can give it a companion object just like UInt and Bool do * * Moved strong enums into experimental package * Non-literal UInts can now be cast to enums with apply() rather than fromBits() * Reduced code-duplication by moving some functions from EnumType and Bits to Element
2018-10-03Add DataMirror.modulePorts (#901)Richard Lin
2018-09-14Give type annotation to litOption. (#887)grebe
The litOption field currently has no type that can be inferred. Some subtypes override it and give it a type, but the original declaration should have a type so things like bundles can override it.

2018-09-07Add SInt ScalaDoc documentationSchuyler Eldridge
Adds documentation of Arithmetic, Bitwise, and Comparison operators for SInt. The duplication of documentation between UInt and SInt strongly indicate a unification around Num would make sense. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>
