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
2018-10-12Strong 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

2018-03-02Fix for 792 (#793)Richard Lin
Makes Builder.updateBundleStack a bit stricter in deciding how many stack frames to discard by additionally matching against method names and deleting stack frames at or above the frame currently being inserted.
2018-02-28Refactor Annotations (#767)Jack Koenig
* Generalize ChiselAnnotation This allows us to delay creation of Annotations till elaboration is complete. Also update all annotation-related code. * Add RunFirrtlTransform Use a Chisel-specific RunFirrtlTransform API to preserve behavior of old ChiselAnnotation (now called ChiselLegacyAnnotation) * Use unique test directories in ChiselRunners.compile
2018-02-08Make uncloneable IO deprecated instead of error, improve error handling (#771)Richard Lin
It appears #754 breaks more code than I thought, so this makes it a soft error (with a runtime deprecation warning - to get people to fix their stuff before we break it for real) for now. This additionally changes the autoclonetype errors to be more deterministic (reporting class names instead of object names) in the most common cases, to allow the deprecations manager to deduplicate warnings.
2018-02-07Better support for autoclonetype of nested Bundles (#769)Richard Lin
* Better support for autoclonetype of nested Bundles * Move bundleStack to dynamicContext * prefer $outer if available, make guesses distinct * Catch IllegalAccessException in autoclonetype In strange circumstances this type of exception can occur when accessing $outer
2018-01-23Runtime API deprecation warnings (#761)Richard Lin
Add runtime warnings for use of deprecated Chisel methods. This is done using a macro that takes the message from a `@deprecated` annotation, and adds a call to `Builder.deprecated`. Reasoning is that by default, Scala doesn't print all deprecations, and that it's somewhat tricky to notice them - yet some support questions revolve around the use of deprecated and terribad API. This now prints warnings for uses of deprecated functions at runtime, and aggregates them by error and line to avoid spam. Also included is convenient information on enabling scalac deprecations. This also changes how line numbers for Chisel's error facility is determined, using prefix string comparison of the stack trace element classnames, instead of checking if the class is a subtype of UserModule. The previous one (specifically, calls to Class.forName) seems to interact badly with reflection-based cloneType when called at scale. This should also give more accurate reporting of errors that are in user code but outside of a UserModule. It turns out that `@deprecated` on macro functions don't do anything, so this changes the tags to the functions that the macros point to, which seems to work properly. It also turns out that there's a bunch of uses of deprecated functions in chiselTests which needs to be fixed. Not all `@deprecated` functions are also annotated with `@chiselRuntimeDeprecation`, because they're still used in Chisel internals, and we can't track whether they're called by the user or by Chisel and it will give a misleading error. These are a small amount of functions.
2017-11-06Default to unidoc for scaladoc generation. (#715)Jim Lawson
Disambiguate DontCare reference in initializeSingletons() avoiding compilation error during unidoc generation.
2017-10-26Invalidateapi (#645)Adam Izraelevitz
* Require explicit connection to DontCare to generate "is invalid". * Add tests for RefNotInitializedException. Currently, we fail the when ... otherwise ... * Disable ScalaTest shrinking on error in ComplexAssignSpec. * fix broken merge; still some binding issues * cleanup DontCare connection checks; add missing directions to test module IOs * Have library code inherit compileOptions from the enclosing Module (if it exists). * work around current firrtl uninitialized references with Strict compile options and explicitInvalidate * more CompileOptions cleanup; move test-specific defines to package object * minimize differences with master * set default CompileOptions.explicitInvalidate to false until we fix the FIRRTL when issue * ignore the StrictCompiler property checks (until CompileOptions.explicitInvalidate is defaulted to true) * Revert "more CompileOptions cleanup; move test-specific defines to package object" This reverts commit e4486edcba990d150e76e08a2fc6abca033556e0. * Revert "work around current firrtl uninitialized references with Strict compile options and explicitInvalidate" This reverts commit 426faa430a62c3dac2dbdf33044d3386d4243157. * remove unused code * Convert to binding-based DontCare implementation * comment cleanup to minimize differences with master * Tentatively remove possibly redundant DefInvalid on module ports. * Respond to code review change request. - backout build.sbt change - correct indentation - handle bulk of DontCare semantics in elemConnect() - have DontCare extend Element, not Data (eliminate most Object specific methods - add comments indicating reason for explicit DontCare connections * Initialize test elements without requiring a DontCare. * Respond to review change requests. - DontCare should work on left or right side in BiDirectional connections - call bind() to set DontCare binding instead of messing with internal variables - DontCares are only equivalent with DontCares - clean up processWhens() definition * Eliminate DontCare connection to inputs in MonoConnect(). * Pull aggregates apart for the purpose of DontCare connections. * Restore the explicit (conditionally executed) ports DefInvalidin ImplicitModule() * Don't add DontCare's to the module list of _ids. * Add missing DefInvalid() to LegacyModule(). * Respond to review requests: add DontCare BiConnect Vec, remove null parent hack to avoid addId(), initialize singletons early in Builder * Move DontCare out of chisel3.experimental.

2017-06-26Directions internals mega-refactor (#617)Richard Lin
Part 1 of mega-change in #578 Major notes: - Input(...) and Output(...) now (effectively) recursively override their elements' directions - Nodes given userDirection (Input, Output, Flip - what the user assigned to _that_ node) and actualDirection (Input, Output, None, but also Bidirectional and BidirectionalFlip for mostly Aggregates), because of the above (since a higher-level Input(...) can override the locally specified user direction). - DataMirror (node reflection APIs) added to chisel3.experimental. This provides ways to query the user given direction of a node as well as the actual direction. - checkSynthesizable replaced with requireIsHardware and requireIsChiselType and made available in chisel3.experimental. Internal changes notes: - toType moved into Emitter, this makes the implementation cleaner especially considering that Vec types can't be flipped in FIRRTL. This also more clearly separates Chisel frontend from FIRRTL emission. - Direction separated from Bindings, both are now fields in Data, and all nodes are given hierarchical directions (Aggregates may be Bidirectional). The actualDirection at the Element (leaf) level should be the same as binding directions previously. - Bindings are hierarchical, children (of a, for example, Bundle) have a ChildBinding that points to their parent. This is different than the previous scheme where Bindings only applied at the Element (leaf) level. - Lots of small misc clean up. Future PRs will address other parts of #578, including stricter direction checks that aren't a side-effect of this internal refactor, stricter checks and splitting of binding operations (Wire vs. WireInit), and node operations not introduced here (getType and deprecation of chiselCloneType). Since those shouldn't mess with internals, those should be much smaller.

2017-01-31Make Module and Bundle properly use empty namespacesJack
Fix default suggested name of Module instances (now based on desired name rather than actual assigned name). Remove parent/child relationship from Namespace. Previously, Module and Bundle namespaces were "children" of the Module definition namespace. This could lead to collisions that would give unexpected names for module instances or Bundle elements. In particular, otherwise identical modules that instantiate other identical modules in such a way that the instance cannot be named via reflection would not be deduplicated because the names of the instances would collide with the names of the modules in the Builder.globalNamespace.

2017-01-20Add Record as new superclass of Bundle (#366)Jack Koenig
Record gives uses the power to create collections of heterogenous elements. Bundle is a special case of Record that uses reflection to populate the elements of the collection. Bundle also attempts to implement cloneType whereas users of Record are required to supply one.
