  • Viewing and debugging HDL designs having SystemVerilog interface constructs
    Patent number: 8671383
    Abstract: Methods and systems for viewing and debugging HDL designs having SystemVerilog interface constructs are provided. An HDL design code is received, wherein the design code comprises a first module, a second module and a SystemVerilog interface construct. A first object corresponding to the first module, a second object corresponding to the second module and an interface object corresponding to the interface construct are displayed in a schematic view. The interface object is disposed between the first and second objects, and a shape of the interface object is different from that of the first and second objects. The interface signals from the first object to the second object and the interface signals from the second object to the first object pass through the interface object.
