  78. 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.

    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.
