Returns true if two types are weakly equivalent.

See the FIRRTL spec, Section 4.6, for a full definition of this. Roughly, the oriented types (the types with any flips pushed to the leaves) must match. This allows for types with flips in different positions to be equivalent.

◆ canonicalizeTarget()

◆ foldFlow()

Compute the flow for a Value, val, as determined by the FIRRTL specification.

This recursively walks backwards from val to the declaration. The resulting flow is a combination of the declaration flow (output ports and instance inputs are sinks, registers and wires are duplex, anything else is a source) and the number of intermediary flips. An even number of flips will result in the same flow as the declaration. An odd number of flips will result in reversed flow being returned. The reverse of source is sink. The reverse of sink is source. The reverse of duplex is duplex. The accumulatedFlow parameter sets the initial flow. A user should normally not have to change this from its default of Flow::Source.

◆ isRecognizedPrintfEncodedVerif()

bool circt::firrtl::isRecognizedPrintfEncodedVerif ( PrintFOp printOp )

Classifier for legacy verif intent captured in printf + when's.

Chisel has a tendency to emit complex assert/assume/cover statements encoded as print operations with special formatting and metadata embedded in the message literal.

One variant looks like:

when invCond:

  stop(clock, UInt<1>(1), 1)

Depending on the nature the verification operation, the stop may be optional. The Scala implementation simply removes all stops that have the same condition as the printf.

Returns true if the destination is at least as wide as a source.

Returns true if the destination is at least as wide as an equivalent source.

The source and destination types must be equivalent non-analog types. The types are recursively connected to ensure that the destination is larger than the source: ground types are compared on width, vector types are checked recursively based on their elements and bundles are compared field-by-field. Types with unresolved widths are assumed to fit into or hold their counterparts.

A marker for parser features that are currently missing from the spec.

Features use this version if they have not been added to the documentation in the chipsalliance/firrtl-spec repository. This allows us to distinguish features that are released in the next version of the spec and features that are still missing from the spec.

Definition LowerAnnotations.cpp:144

Resolution and application of a "firrtl.annotations.NoTargetAnnotation".

This should be used for any Annotation which does not apply to anything in the FIRRTL Circuit, i.e., an Annotation which has no target. Historically, NoTargetAnnotations were used to control the Scala FIRRTL Compiler (SFC) or its passes, e.g., to set the output directory or to turn on a pass. Examples of these in the SFC are "firrtl.options.TargetDirAnnotation" to set the output directory or "firrtl.stage.RunFIRRTLTransformAnnotation" to cause the SFC to schedule a specified pass. Instead of leaving these floating or attaching them to the top-level MLIR module (which is a purer interpretation of "no target"), we choose to attach them to the Circuit even they do not "apply" to the Circuit. This gives later passes a common place, the Circuit, to search for these control Annotations.
