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
2018-10-05Change InlineSpec to expect "_" and not "$"Schuyler Eldridge
A FIRRTL change to inlining changes the inlined instance delimiter to "_" from "$". This change is reflected here in an update to the associated Chisel tests for the Inline API. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>

* Ability to load memories at simulation startup * first pass * create annotation * create skeleton Transform * Work in progress Building out transform and pass now * Support for LoadMemory annotation * Creates chisel and firrtl LoadMemory annotations * LoadMemoryTransform converts annotation into BlackBox InLine * Simple test that verilog bound modules get created. * Support for LoadMemory annotation * Supports Bundled/multi-field memories * more tests * support for `$readmemh` and `$readmemb` * warns if suffix used in file specification. * Support for LoadMemory annotation * Use standard chisel annotation idiom * Support for LoadMemory annotation * Fixes for @seldridge nits and super-nits * Support for LoadMemory annotation - transform now only runs if emitter is an instance of VerilogEmitter - suffixes on memory text files are now respected - if suffix exists and memory is aggregate, aggregate sub-fields will now be inserted before suffix - every bind module created gets a unique number - this is required when multiple loaded memories appear in a module - this should be generalized for other uses of binding modules * Support for LoadMemory annotation - remove un-needed suffix test * Support for LoadMemory annotation - remove instance walk, now just processes each module * Support for LoadMemory annotation - Move LoadMemoryTransformation into Firrtl for treadle to access it. * Support for LoadMemory annotation - One more bug in suffix handling has been eliminated * Support for LoadMemory annotation - remove unused findModule per jackkoenig - fixed complex test, bad filename edge case * Support for LoadMemory annotation - changed to not use intellij style column alignment for : declarations * Load memory from file Fixes based on @jkoenig review - remove unused BindPrefixFactory - Moved code from CreateBindableMemoryLoaders into to LoadMemoryTransfrom - Made map to find relevant memory annotations faster - Made map to find modules referenced by annotations faster - Made things private that should be private - DefAnnotatedMemorys are no longer referenced, shouldn't be found here. - println of error changed to failed * Loading memories from files - Many changes based on review - move stuff into experimental - clean up annotation manipulation - manage tests better - use more standard practices for transform * Loading memories from files - More review changes - Move doc from annotation to the object apply method that generates the annotation - Make scalastyle directives more specific - Use more efficient collect to generate name to module map - Made lines obey style length limit - a couple of cleanups of imports in tests - removed some commented out code - optimized checking for lines using .exists - use _ for unused variable in match
2018-08-23Add FlattenInstance APISchuyler Eldridge
This adds a new trait, FlattenInstance, to chisel3.util.experimental. When mixed into a module or a specific instance this trait will "flatten", i.e., "inline that module and all of its submodules". This includes testing (additions to InlineSpec) and ScalaDoc documentation. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>
2018-08-23Add InlineInstance APISchuyler Eldridge
This adds a new trait, InlineInstance, to chisel3.util.experimental. This trait, when mixed into a specific module or instance, will "inline" that module, i.e., "collapse a module while preserving it's submodules." This includes testing (InlineSpec) and ScalaDoc documentation. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>

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>

2018-03-23Fallback null insertion for autoclonetype (#801)Richard Lin
If autoclonetype is unable to determine an outer class, this attempts to insert a null (and give a deprecation warning), preserving old behavior (in some cases) where the new behavior doesn't work. This doesn't provide full compatibility with old autoclonetype: this does not attempt null insertion in the general first argument (if it's not an outer class reference). Reasoning is that inserting a null for an explicit argument is probably not the right thing to do, and will likely cause a difficult-to-debug NullPointerException (whereas that would be unlikely for an outer class, which is not always referenced in Bundle subclass code).
2018-03-06Fix SyncReadMem.read; add test (#796)Andrew Waterman
SyncReadMem.read with an enable signal currently only works in compatibility mode, where Wires are implicitly initialized to DontCare. Fix by explicitly assigning DontCare to the Wire. This might fix #775.
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.
