Abstract Syntax Tree for Calyx

Structs§

BitNum: Custom bitwidth numbers
Cell: The Cell AST nodes.
ComponentDef: AST statement for defining components.
FSMState: A single state in an FSM.
Fsm: A fsm block has a name, attributes, and FSMRules that correspond to all the states within the fsm.
Group
Guard: Guards expr using the optional guard condition guard.
NamespaceDef: Corresponds to an individual Calyx file.
Proto: Prototype of the cell definition
StaticGroup
StaticGuard: Guards expr using the optional guard condition guard.
StaticWire: Data for the -> structure statement.
Wire: Data for the -> structure statement.

Atom: Atomic operations used in guard conditions and RHS of the guarded assignments.
Control: Control AST nodes. Since enables and static enables are indistinguishable to the AST, there is single Control Enum for both Static and Dynamic Control
GuardComp: Possible comparison operators for guards.
GuardExpr: The AST for GuardExprs
NumType
Port: Statement that refers to a port on a subcomponent. This is distinct from a Portdef which defines a port.
StaticGuardExpr: The AST for StaticGuardExprs
Transition: The next state transition for an FSM.
