2019-08-13Use a PhaseManager for Driver internalsSchuyler Eldridge
Migrate Driver to use a PhaseManager to internally resolve Phase ordering. This requires the use of an identity node to adequately describe the necessary prerequisite/dependents. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@gmail.com>

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.

2019-08-08Require target is hardware for Vec.apply(a: UInt)Schuyler Eldridge

Muxes and resets are only isomorphic with synchronous reset. Use a reset instead of a conditional to make this async-reset-safe.

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>

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.

* Add width utility functions to avoid incorrect usage of bare log2Ceil(). * Respond to comments: Remove apply(Data) method. Change name(s) to signedBitLength, unsignedBitLength. * Respond to comments - don't be lazy. Independently calculate the bit length to verify correct operation. * Respond to comments - return in.bitLength - 0 (not 1) for 0 * Respond to comments - update wdith for signed 0; add explicit tests. * Add comment expressing zero width wire assumption.
