2020-02-06Emit FIRRTL andr, orr for Bits.{andR, orR}Schuyler Eldridge
Change the emission strategy for Bits methods andR and orR to emit FIRRTL bitwise reduce operations andr and orr. Add two tests that assert the correct behavior of these operations in BitwiseOpsSpec. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>

2020-01-25Remove redundancy code (#1296)Leway Colin
* Remove redundancy code * Remove blank line * BitPat supports whitespace and underscores, presumably for human readability. The BitPat.parse factory though did not remove these from the returned count.

2020-01-22Change when/switch thunk type to Any (#1308)Schuyler Eldridge
* Change when thunks return type to Any Changes the type of the thunk for when and WhenContext methods from call-by-name Unit to call-by-name Any. This prevents a warning (-Ywarn-value-discard) where a when thunk is returning something other than Unit that is then discarded, e.g., another WhenContext. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com> * Change switch thunk return to type to Any Changes the type of switch thunks from call-by-name Unit to call-by-name Any. This prevents a warning (-Ywarn-value-discard) when the internals of a switch block return something other than Unit which is then discarded.

decimal - made .F and .I work for creating fixed point and interval lits from big decimal - Added NumObject trait which provides new math conversions - Made a Num object that extends NumObject - Add this trait to FixedPoint and Interval for backward compatibility - Removed code that is now in NumObject, keeping things DRY - Add tests to FixedPointSpec to show lit conversion to double and big decimal - Add tests to IntervalSpec to show lit conversion to double and big decimal - Add tests to LiteralExtractorSpec to show general math conversions between BigInts with binary points and double and big decimal

This is just a band aid until an Aggregate `isLit()` method (for which work has begun) is implemented.

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.

2019-10-18Interval 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

2019-09-16Da steve101 tree reduce (#485)Jack Koenig
* Add a tree reduce function to Vec * Change function names of reduce operation function in Vec * Change reference to single layer operation in Vec.reduce * Commint name change for pair macro * Remove pair, call not necessary and can just be used from grouped(2) and map * Changed to reduceTree, added default identity function for single reduce. * Change style of Vec.reduceTree and tests to chisel3 and canonical Scala style * Cleanup Vec initialization, implicitCompileOptions
2019-09-11Move dontTouch, RawModule, and MultiIOModule out of experimental (#1162)Jim Lawson
* Move dontTouch out of experimental package. * Move RawModule, MultiIOModule out of experimental. * Respond to comments - Move LagacyModule from experimental to internal. *NOTE*: At some point, these module definitions (especially those in separate packages) should be moved to individual files at the appropriate location in the source tree. The current organization is purely to support comparison with prior versions. * Fix up a few more imports.

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 Aspects to Chisel, enabling a mechanism for dependency injection to hardware modules.
2019-08-08Require target is hardware for Vec.apply(a: UInt)Schuyler Eldridge
Adds a check that a Vec being indexed by a UInt is, in fact, a hardware type. This includes a test for this. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>
2019-08-01Flatten *FactoryBase hierarchySchuyler Eldridge
This renames all *FactoryBase traits to *Factory, removes transparent *Factory objects, and propagates this flattened hierarchy throughout the codebase. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>

2019-07-31Clarify Module deprecationsSchuyler Eldridge
This adds a clarification to the deprecation message for RawModule, MultiIOModule, UserModule, and ImplicitModule. While these were technically deprecated "since the beginning of time", this adds a comment that these aliases will be removed in 3.3. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>

2019-07-24Fix Num.+ ScaladocSchuyler Eldridge
Change Num.+ Scaladoc to state that this is not a growing addition. Note that this is problematic either way as this macro is resolved to an abstract method. Classes implementing this typeclass are technically free to violate what we put in the Scaladoc here. h/t @kammoh Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>
2019-07-18Support Analog DontCare bulk-connect (#1056)Richard Lin
Short-term patch to enable this useful behavior. In the future, we may want to rearchitect the type system and/or rethink the more edge-case connect behavior.
