Abstract

A design tool for designing a system includes a display device with a first visualization pane showing a symbolic representation of a connection between a first port and a second port of the system and a second visualization pane showing an unconnected port of the system. A text entry pane on the display device shows a textual definition of the connection. An optional status pane shows a textual log of user-performed actions relating to construction of the system.

Claims

1. A design tool for designing a system, comprising:

a display device displaying a user interface including

a first visualization pane showing a symbolic representation of a first connection between a first port of a first element of the system and a second port of a second element of the system as a first port symbol, a second port symbol, and a connector symbol;

a second visualization pane showing a first unconnected port of the first element of the system as a third port symbol; and

a text entry pane showing a textual definition of the first connection.

2. The design tool of claim 1, wherein the system is an integrated circuit system.

3. The design tool of claim 1, wherein the system is a software system.

4. The design tool of claim 1, further comprising:

a window selectively displayed on the display device providing a menu of a plurality of interface type symbols representing a corresponding plurality of interface types according to behavioral attributes of the interface types.

5. The design tool of claim 4, wherein the plurality of interface type symbols includes a symbol representing a pre-defined interface type and a symbol representing a general interface type.

6. The design tool of claim 4, wherein the plurality of interface type symbols includes a first symbol representing a packet interface type, a second symbol representing an access interface type, a third symbol representing a compute interface type, a fourth symbol representing a notify interface type and a fifth symbol representing a general interface type.

7. The design tool of claim 6, wherein the general interface type is a user-definable interface type.

8. The design tool of claim 7, wherein a first general interface type is defined as a bit-vector.

9. The design tool of claim 1, wherein the third port symbol of the first element of the system is arranged on the displayed second visualization pane in a columnar fashion relative to the first port symbol of the system.

10. The design tool of claim 1, wherein the first port symbol is of a first interface symbol type and the second port symbol is of the first interface symbol type.

11. The design tool of claim 1, further comprising a status pane showing a textual log of user-performed actions relating to construction of the system.

12. The design tool of claim 1, wherein the user interface further includes a context menu associated with the text entry pane, the context menu being displayed according to a first portion of the textual definition being entered into the test entry pane by a user, the context menu displaying unused ports compatible for connection to the first portion of the textual definition.

13. A computer system including memory storing computer-readable instructions for configuring the computer system to operate as the design tool of claim 1.

14. A computer-implemented method of designing a system, comprising:

providing a library of system elements of the system, the system elements causing a computer to perform operations including;

defining interface instantiations for at least two system elements according to behavioral attributes of interface types in a system design tool, the interface types including at least two interface types;

entering a first text description of a first connection between a first port of a first element of the system and a second port of a second element of the system into the system design tool;

displaying the first text description in a text entry pane on a display device of the system design tool; and

then

displaying a first port symbol of a first interface type representing the first port, a second port symbol of the first interface type representing the second port, and a connection symbol between the first port symbol and the second port symbol in a first visualization pane of the display device, and

displaying a third port symbol representing a third port of the first element on a second visualization pane of the display device being adjacent to the first visualization pane, the third port being a first unconnected port of the first element.

15. The method of claim 14, wherein the third port symbol represents a second interface type of the first element and is graphically distinctive from the first port symbol.

16. The method of claim 14, wherein entering a first portion of the first connection defines a port and activates a context menu on the display device indicating unconnected ports in the second visualization pane suitable for connection to the port.

17. The method of claim 16, wherein the operations further include:

selecting an unconnected port from the context menu, wherein a remaining portion of the first connection is automatically entered in the first text description of the first connection.

18. The method of claim 14, wherein:

the system is a field-programmable gate array (“

FPGA”

) system,

the first element of the FPGA system has a first plurality of interface instantiations and the second element of the FPGA system has a second plurality of interface instantiations, and

each of the first plurality of interface instantiations and each of the second plurality of interface instantiations is displayed in combination according to connection status in the FPGA system on the first visualization pane and on the second visualization pane.

19. A non-transitory computer-readable device storing computer-readable instructions, which, when executed by the computer, perform the method of claim 14.
