* 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.
2017-08-17Use firrtl elses in elsewhen/otherwise case emission (#510)Albert Magyar
Preprocess chisel3 IR before emission to determing whether whens have alternatives.

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.

Used for stitching Verilog inout through Chisel Modules (from BlackBox to BlackBox)

Remove modName from Module
2016-11-18Add support for parameterized BlackBoxesjackkoenig
Also restrict black boxes to not allow hardware inside of them since it was being silently dropped anyway. Resolves #289

2016-09-21Make implicit clock name consistent (#288)Andrew Waterman
In the Chisel frontend, the implicit clock is named clock, but in the generated FIRRTL, it is named clk. There is no reason for this discrepancy, and yet fixing it is painful, as it will break test harnesses. Better to take the pain now than later. Resolves #258.
2016-09-07Fix bug in Printable FullName of submodule portjackkoenig
Printable was using HasId.instanceName to get full names of Chisel nodes. instanceName uses the parent module of the HasId to get the Component to use in calling fullName on the underlying Ref. Unfortunately this means that any reference to a port of a instance will leave off the instance name. Fixing this required the following: - Add Component argument to Printable.unpack so that we can call Arg.fullName directly in the Printable - Pass the currently emitting module as the Component to Printable.unpack in the Emitter - Remove ability to create FullName Printables from Modules since the Module name is not known until after the printf is already emitted This commit also updates the PrintableSpec test to check that FullName and Decimal printing work on ports of instances
2016-09-07Add Printable (#270)Jack Koenig
Printable is a new type that changes how printing of Chisel types is represented It uses an ordered collection rather than a format string and specifiers Features: - Custom String Interpolator for Scala-like printf - String-like manipulation of "hardware strings" for custom pretty-printing - Default pretty-printing for Chisel data types
2016-08-25fix a bug in setModNameDonggyu Kim
2016-08-21provides signal name methods for firrtl annotation and chisel testersDonggyu Kim
* signalName: returns the chirrtl name of the signal * pathName: returns the full path name of the signal from the top module * parentPathName: returns the full path of the signal's parent module instance from the top module * parentModName: returns the signal's parent **module(not instance)** name.
2016-08-09Support Module name overrides with "override def desiredName"Andrew Waterman
The API allowed this before, but not safely, as users could create name conflicts. This exposes the pre-deduplication/sanitization naming API, and closes the other one.
