2021-09-05Add Definition and Instance API (#2045)Adam Izraelevitz
This introduces a new experimental API for module instantiation that disentagles elaborating the definition (or implementation) from instantiation of a given module. This solves Chisel's longstanding reliance on "Deduplication" for generating Verilog with multiple instances of the same module. The new API resides in package chisel3.experimental.hierarchy. Please see the hierarchy ScalaDoc, documentation, and tests for examples of use.

2021-08-23Emit .fir lazily, overcomes JVM 2 GiB String limitJack Koenig
2021-08-23Remove chisel3's own firrtl Emitter, use firrtl SerializerJack Koenig
This will be slightly slower as it involves converting from Chisel modules to FIRRTL modules before turning them into Strings. This cost is somewhat mitigated by doing that conversion lazily such that we never materialize the entire firrtl Circuit in memory, only 1 module at a time.

2021-08-12Add DataView (#1955)Jack Koenig
DataView is a mechanism for "viewing" Scala objects as a subtype of `Data`. Often, this is useful for viewing one subtype of `Data`, as another. One can think about a DataView as a cross between a customizable cast and an untagged union. A DataView has a Target type `T`, and a View type `V`. DataView requires that an implementation of `DataProduct` is available for Target types. DataProduct is a type class that provides a way to iterate on `Data` children of objects of implementing types. If a DataView is provided for a type T to a type V, then the function .viewAs[V] (of type T => V) is available. The object (of type T) returned by .viewAs is called a "View" and can be used as both an rvalue and an lvalue. Unlike when using an .asTypeOf cast, connecting to a "View" will connect to the associated field or fields of the underlying Target. DataView also enables .viewAsSupertype which is available for viewing Bundles as a parent Bundle type. It is similar to .viewAs but requires a prototype object of the Target type which will be cloned in order to create the returned View. .viewAsSupertype maps between the corresponding fields of the parent and child Bundle types.

2021-07-06Make printf return BaseSim subclass so it can be named/annotated (#1992)Deborah Soung
2021-06-29Change behavior of aop.Select to not include CloneModuleAsRecordJack Koenig
Previously, CloneModuleAsRecord clones would result in the same BaseModule object coming up multiple times when using APIs like .instances, .collectDeep, and .getDeep. This was not the intended behavior and can lead to very subtle bugs.

2021-06-10Stop Emitting BlackBoxResourceAnno (#1954)Schuyler Eldridge
* Change HasBlackBoxResource to Resolve Resources Change HasBlackBoxResource to resolve resources immediately and emit BlackBoxInlineAnno instead of a BlackBoxResourceAnno. This removes the need for a FIRRTL compiler to grok the Java Resource API in order to handle BlackBoxResourceAnno. Emit BlackBoxInlineAnno from HasExtModuleResource instead of BlackBoxResourceAnno.

2021-05-09Fix ShiftRegister with 0 delay. (#1903)Jiuyang Liu
* Add test to check ShiftRegister(s) with delay is 0. This should break ShiftRegister(x, 0) since last is not exist in a empty Seq. Originally, test only test 1 to 4, which missed a potential bug from #1723. * Fix ShiftRegister with 0 delay. if ShiftRegisters is empty, java will complain: ``` java.util.NoSuchElementException scala.collection.LinearSeqOptimized.last(LinearSeqOptimized.scala:150) ``` This fix this issue and return `in` directly when ShiftRegister size is 0.

2021-03-18Don't toggle top.cpp clock and reset on same cycle (#1820)Schuyler Eldridge
Change top.cpp to deassert reset one time unit before the clock asserts. This avoids a Verilator simultation issue in top.cpp where the eval() function is only called once per simultation loop. If the clock and reset are both changed and eval() is only called once, then any combinational update due to a change in reset is not visible to the sequential logic. This avoids issues where the downstream compilation utilities move synchronous reset logic outside of an always block that describes a synchronous reset flip flop. Reset now deasserts on time unit 10 and the clock ticks on time unit 11. h/t @albert-magyar Signed-off-by: Schuyler Eldridge <schuyler.eldridge@sifive.com>
