2019-11-05Support literals cast to aggregates as async reset reg init values (#1225)Jack Koenig
Accomplished by changing the code gen for casting literals to aggregates. Rather than connecting the literal to a wire that is then bit selected from, just bit select from the literal which saves the creation of an intermediate wire and matches FIRRTL's semantics for legal async reset initial values.

2019-10-21Fix BoringUtils.bore for internal boringSchuyler Eldridge
This fixes a bug where internal boring using BoringUtils.bore would fail because it was using instanceName which cannot be called before the module closes. Previously, this meant that BoringUtils.bore would work for boring instances (which are closed in a parent), but not for boring signals in the current, unclosed module.

2019-10-18Interval Data Type Support for Chisel (#1210)Chick Markley
Plan to be released with 3.3. Breaks experimental Range API. Adds new Interval type and associated support. This commit adds the following: - Renamed Range to IntervalRange to avoid name collision with scala Range - Changed RangeTransform macro to Return an IntervalRange - Improved error messages on missing comma or decimal - Added notational support for binary point - Some formatting cleanup also - SIntFactory - Change to use IntervalRange API - UIntFactory - UInt from range has custom width computation - It does not need to deal with lowerbound extending bit requirements - Code to handle special case of range"[0,0]" to have a width of 1 - IR.scala - Removed Bound and other constraint code that was duplicating firrtl stuff - Added new RangeType - Added IntervalRange class and object - RangeSpec - modified just a bit to handle notational differences - previous range interpolator returned tuple now returns IntervalRange - Add IntervalType to emitter - Added IntervalSpec with many tests - Added ScalaIntervalSimulatorSpec which tests golden model for Interval - Added ScalaIntervalSimulator which is a golden model for Interval - This gold may not have been polished to a high sheen - Add IntervalLit cases to Converter - Add Interval PrimOps to IR - asInterval, wrap, squz, clip, setp, decp, incp - Add IntervalLit class to IR - Add Interval to MonoConnect - Add Interval Type to Bits (in experimental package) - add conversions to Interval from other types - Add Interval clone stuff to Data - Add Literal creation helpers to chisel3 package - these may move to experimental if I can figure that out

2019-08-13Add support for asynchronous reset (#1011)Jack Koenig
Adds new AsyncReset and "abstract" Reset types. Reset is inferred in FIRRTL to be either AsyncReset or Bool. The "reset type" of a register is set by the type of its reset signal: val asyncReset: AsyncReset = IO(Input(AsyncReset())) val syncReset: Bool = IO(Input(Bool())) val abstractReset: Reset = IO(Input(Reset())) val asyncReg = withReset(asyncReset) { RegInit(0.U) } val syncReg = withReset(syncReset) { RegInit(0.U) } val inferredReg = withReset(abstractReset) { RegInit(0.U) } AsyncReset can be cast to and from Bool. Whereas synchronous reset is equivalent to a mux in front of a flip-flop and thus can be driven by logic, asynchronous reset requires that the reset value is a constant. This is checked in FIRRTL. Inference of the concrete type of a Reset occurs based on the type the Reset's drivers. This inference is very simple, it is simple forward propagation of the type, but it allows for writing blocks and modules that are agnostic to the reset type. In particular, the implicit `reset` value in MultiIOModule and thus Module is now concretely an instance of Reset and thus will be inferred in FIRRTL.

* Added documentation to Decoupled, Conditionals, Counter * Fixed private Counter class error * Move Counter class deprecation and re-definition into util package object. * Revert "Move Counter class deprecation and re-definition into util package object." This reverts commit f61bdddf7051522363e1d203fcd46b512047c87d. * Restore the old Counter definition and address this in a separate PR. We can move the deprecation warning and the type definition into the util package object (see f61bdddf7051522363e1d203fcd46b512047c87d), but then we fail tests using Counter with a `ScalaReflectionException` in Aggregate.scala:779 (in def cloneType) when: `Some(mirror.reflect(this).symbol)` generates `type Counter is not a class`. * Made @ducky64 change to Counter doc Used to generate an inline (logic directly in the containing Module, no internal Module is created) hardware counter.
2019-05-22Make Driver a ChiselStage compatibility layerSchuyler Eldridge
This converts the original chisel3.Driver to use chisel3.stage.ChiselStage. This is implemented in the following way: 1. ExecutionOptions are converted to an AnnotationSeq 2. The AnnotationSeq is preprocessed using phases contained in the Chisel DriverCompatibility objects. One of these *disables* the execution of FirrtlStage by ChiselStage. 3. ChiselStage runs on the preprocessed AnnotationSeq 4. The input ExecutionOptionsManager is mutated based on the output of ChiselStage. 5. The FIRRTL stage is re-enabled if it's supposed to run and selected FIRRTL DriverCompatibility phases run. 6. FirrtlStage runs 7. The output AnnotationSeq is "viewed" as a ChiselExecutionResult This modifies the original DriverSpec to make it more verbose with the addition of info statements. The functionality of the DriverSpec is unmodified. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>

2019-05-22Add Driver Compatibility LayerSchuyler Eldridge
This includes phases necessary to provide backwards compatibility with the old Chisel3 Driver. These are placed in a DriverCompatibility object inside chisel3.stage.phases. The following four phases are included: - AddImplicitOutputFile (from a TopNameAnnotation) - AddImplicitOutputAnnotationFile phase - DisableFirrtlStage (to disable ChiselStage running FirrtlStage) - MutateOptionsManager (to update options after ChiselStage) - ReEnableFirrtlStage (to renable FirrtlStage if needed) Additionally, this adds a view of a ChiselExecutionResult for providing the legacy return type of the Chisel Driver.
