Abstract:
A method for data propagation analysis. A data propagation diagram for a circuit design is generated. The data propagation diagram includes a plurality of nodes and a plurality of edges connecting the nodes. The nodes represent data locations in the circuit design and the edges represent data propagation paths between the data locations in the circuit design. A signal trace specifying signal values for the circuit design is analyzed to determine whether data at a first data location of the data locations during a first clock cycle is causally related to the data at a second data location of the data locations during a second clock cycle. A visual animation is displayed on the data propagation diagram indicating movement of the data between a first node of the nodes corresponding to the first data location and a second node of the nodes corresponding to the second data location.
