Graph Representation¶

Netlist¶

class frontend.Netlist[source]¶: A netlist is a collection of modules

Module¶

class frontend.Module[source]¶

Module class represents a module in a Verilog netlist. In LEAP, a module is:

A Frame, which is a collection of ports
A CDFG (BNGraph), which is the control/data flow graph of the module
A ParameterHandler, which describes the reconfigurable parameters of the module
A Macros, which contains the macros defined in the module (constant values)

Port¶

class frontend.Port(variable: DFGNode, range: Optional[Range] = None, direction: Optional[PortDirection] = None, type: Optional[PortType] = None)[source]¶: A port is the elementary unit of a frame.

Assignment¶

class frontend.Assignment(target: DFGNode, expression: DFGNode, condition: Optional[DFGNode] = None, event: Optional[DFGNode] = None, isBlocking: bool = True)[source]¶

Assignments are the elementary statements in the module.

target (DFGNode): the target variable
expression (DFGNode): the expression to be assigned to the target
condition (DFGNode): the condition under which the assignment is valid
event (DFGNode): the event under which the assignment is valid
