  2. sealed abstract class CircuitForm extends Ordered[CircuitForm]

    Current form of the Firrtl Circuit

    Current form of the Firrtl Circuit

    Form is a measure of addition restrictions on the legality of a Firrtl circuit. There is a notion of "highness" and "lowness" implemented in the compiler by extending scala.math.Ordered. "Lower" forms add additional restrictions compared to "higher" forms. This means that "higher" forms are strictly supersets of the "lower" forms. Thus, that any transform that operates on HighForm can also operate on MidForm or LowForm

    Most of the chisel toolchain components require a topName which defines a circuit or a device under test.

    Most of the chisel toolchain components require a topName which defines a circuit or a device under test. Much of the work that is done takes place in a directory. It would be simplest to require topName to be defined but in practice it is preferred to defer this. For example, in chisel, by deferring this it is possible for the execute there to first elaborate the circuit and then set the topName from that if it has not already been set.

    Examples:

    1. val optionsManager = new ExecutionOptionsManager("firrtl")
optionsManager.register(
    FirrtlExecutionOptionsKey ->
    new FirrtlExecutionOptions(topName = "Dummy", compilerName = "verilog"))
firrtl.Driver.execute(optionsManager)

      or a series of command line arguments

      2. , 

    2. firrtl.Driver.execute(Array("--top-name Dummy --compiler verilog".split(" +"))

      each approach has its own endearing aspects

  5. object FIRRTLException extends Serializable
    Annotations
    @deprecated
    Deprecated

    (Since version FIRRTL 1.2) External users should use either FirrtlUserException or their own hierarchy

  6. object FirrtlExecutionSuccess

    (Since version FIRRTL 1.2) Use FirrtlStage and examine the output AnnotationSeq directly

  7. case object HighForm extends CircuitForm with Product with Serializable

    High Form

    High Form

    As detailed in the Firrtl specification https://github.com/ucb-bar/firrtl/blob/master/spec/spec.pdf

    Also see firrtl.ir

    Annotations

    Deprecated

    (Since version FIRRTL 1.3) Mix-in the DependencyAPIMigration trait into your Transform and specify its Dependency API dependencies. See: https://bit.ly/2Voppre

  8. case object LowForm extends CircuitForm with Product with Serializable

    Low Form

    Low Form

    The "lowest" form. In addition to the restrictions in MidForm:

    • All aggregate types (vector/bundle) must have been removed
    • All implicit truncations must be made explicit

  9. case object MidForm extends CircuitForm with Product with Serializable

    Middle Form

    Middle Form

    A "lower" form than HighForm with the following restrictions:

    • All widths must be explicit
    • All whens must be removed
    • There can only be a single connection to any element

  10. case object UnknownForm extends CircuitForm with Product with Serializable

    Unknown Form

    Unknown Form

    Often passes may modify a circuit (e.g. InferTypes), but return a circuit in the same form it was given.

    For this use case, use UnknownForm. It cannot be compared against other forms.

    TODO(azidar): Replace with PreviousForm, which more explicitly encodes this requirement.
