2019-05-13RawModule with no reset should be able to use withClock method. (#1065)Chick Markley
* RawModule with no reset should be able to use withClock method. - refactor ClockAndReset - now has `clockOpt: Option[Clock]` and `resetOpt: Option[Reset]` constructor params - convenience methods clock and reset tries to deref the option - ClockAndReset.empty is factory method for (None, None) - In Builder - forcedClock does not check resetOpt now - forcedReset does not check clockOpt now - withClock no longer looks at resetOpt - withReset no longer looks at clockOpt - Module starts with empty ClockAndReset * RawModule with no reset should be able to use withClock method. Refactor again based on @ducky64 comments - refactor away ClockAndReset, now builder just has a - currentClock - currentReset - withClock, withRest, withClockAndReset just use these fields directly * RawModule with no reset should be able to use withClock method. - Fixed typo in withReset handler, now picks up new reset

2019-05-09PRNG state UInt->Vec[Bool], make async reset safeSchuyler Eldridge
Changes the internal state of PRNG to use Vec[Bool] instead of UInt. This fixes an @aswaterman identified future problem with asynchronous reset. A register with an asynchronous reset can only be reset to a literal. Previously, an LFSR would store state as a UInt. If it was not parameterized with a seed it should have its least significant bit reset to something to avoid locking up. It's ideal to not reset the full UInt (better test coverage, decreased reset fanout). However, it's difficult to only reset one bit of a UInt. Conversely, it's trivial to reset one bit of a Vec[Bool]. This also moves PRNG/LFSR closer to a canonical representation of their internal state, i.e., it's natural to think of generalizing Vec[Bool] to arbitrary finite fields (Vec[A <: Field]) whereas UInt is tightly coupled to GF2. Minor updates: - Updates/fixes to some scaladoc - Add assertion to period test to make sure LFSR is changing Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>
2019-05-09Fix treatment of Vec of Analog and Vec of Bundle of Analog (#1091)Jack Koenig
* IO(Analog) fixed for RawModule * Add a Analog Port for RawModule test & spec * Fixes around Module instantiation and ports in AnalogPortRawModuleTest * Shorten Comment * Add Data.isSynthesizable to distinguish SampleElementBinding This helps clarify the notion of being bound but not hardware. Data.topBindingOpt is now used to get the *actual* top binding, including across SampleElements (eg. in Analog checking that the top is bound to a Port or a Wire) * Fix pretty printing for Vec * Refactor tests for Vec of Analog, add test for Vec of Bundle of Analog

2019-05-09Add chisel3.util.random lib w/ LFSR generatorSchuyler Eldridge
Builds out PRNG and LFSR type hierarchy. PRNG is the base class of LFSR of which Galois and Fibonacci are concrete implementations. PRNGs contain state (a UInt) and an update (delta) function. They have a compile-time optional seed to set the PRNG state. The seed/state can also be set at run-time. PRNGs can be run-time parameterized based on how many updates they should do per cycle and whether or not to send the seed through step-count state updates before loading it. (h/t @jwright6323) LFSRs are parameterized in a reduction operation (XOR or XNOR). An LFSR that does NOT have a seed will be automatically initialized to a minimally safe state (set/reset one bit) based on their reduction operation. (h/t @aswaterman) Adds Galois and Fibonacci LFSRs that define appropriate update functions. Companion objects provide helpers to automatically generate maximal period variants. Taps are provide for a very large set of widths. The LFSR companion object provides an apply method to generate a Fibonacci LFSR random variable (like the old LFSR16).
