2018-08-07BoringUtils / Synthesizable Cross Module References (#718)Schuyler Eldridge
This adds an annotator that provides a linkage to the FIRRTL WiringTransform. This enables synthesizable cross module references between one source and multiple sinks without changing IO (the WiringTransform bores through the hierarchy). Per WiringTransform, this will connect sources to their closest sinks (as determined by BFS) or fail if ownership is indeterminate. Make TesterDriver.execute work like Driver.execute: - annotations are included when running FIRRTL - custom transforms are run automatically Also, add a bore method to BoringUtils that allows you to do one source to multi-sink mapping in a single call. This adds a test that this is doing the same thing as the equivalent call via disjoint addSink/addSource. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>

2018-06-25Correcting documentation errors in Arbiter.scala (#839)Brendan Sweeney
Documentation for example had parameters in wrong order, and was missing @param. Additionally, it was lacking a module wrapper. This has been corrected.
2018-06-20Programmatic Port Creation (#833)Jack Koenig
Add chisel3.experimental.IO for programmatic port creation in Raw and MultiIOModules. suggestName is required to name ports that cannot be named by reflection. Two ports cannot be given the same name.

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

2018-02-07Cloning IO with compatibility 🦆 (#754)Richard Lin
Changes the API such that IO(...) clones. All Bundles will need to be clone-able, but auto clone type is expected to handle most cases.
2018-02-02Autoclonetype will clone args that are of type data (#768)Richard Lin
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.

2017-10-05the cloneType and chiselCloneType hot mess 🔥 (#653)Richard Lin
Addresses #419 cloneType is now marked (through comments only) as an internal API. chiselCloneType deprecated (and changed to cloneTypeFull internally, analogous to cloneTypeWidth). chiselTypeOf(data) introduced as the external API to get a chisel type from a hardware object Intended usage: cloning is an implementation detail, and chisel types and hardware objects both should act as immutable types, with operations like Input(...), Reg(...), etc returning a copy and leaving the original unchanged. Hence, the clone operations are all deprecated. Deletes what appears to be an unused Bundle companion object. Input(...), Output(...), Flipped(...) require the object to be unbound

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.

2017-04-26Dropimportnotstrict492 - More updates to get things through rocket-chip. (#592)Jim Lawson
* 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.
