Member Function Documentation

isRoot()

bool circt::firrtl::FieldSource::PathNode::isRoot ( ) const

inline

Roots are operations which define the storage or aggregate value.

Definition at line 40 of file FIRRTLFieldSource.h.

References path.

isSrcTransparent()

bool circt::firrtl::FieldSource::PathNode::isSrcTransparent ( ) const

inline

Transparent sources reflect a value written to them in the same cycle it is written.

These are sources which provide dataflow backwards in SSA during one logical execution of a module body. A port may be transparent (no storage), but not be writable from the side of the instance we are on.

isSrcWritable()

bool circt::firrtl::FieldSource::PathNode::isSrcWritable ( ) const

inline

Writable sources can appear as a LHS of a connect given this node's path.
