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

2018-10-29Turn 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

2018-09-14Give 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.

2018-09-07Put := and <> methods in Connect ScalaDoc groupSchuyler Eldridge
This puts Data's connection methods, `:=` and `<>`, in the ScalaDoc `Connect` group. These groups will propagate through to all children of Data, e.g., UInt, and cause those methods to be grouped in the ScalaDoc of these children. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>
2018-09-07Put do_* methods in SourceInfoTransformMacro groupSchuyler Eldridge
This places all do_* methods (and two unary methods in SInt and FixedPoint that act like do_* methods) inside the ScalaDoc group "SourceInfoTransformMacro". Classes/objects which need information about this group have an additional bare trait mixed in, `SourceInfoDoc`, that provides information about the group and its priority.
