Standard cell architecture layout
Various implementations described herein are directed to providing standard cell architecture layout design. A request to activate a grid is received. A request to place at least one edge of a shape at a particular location on the grid is received from an input device. The at least one edge of the shape is automatically placed in an allowed location based on pre-defined rules.
1. A method for providing standard cell architecture layout design, the method comprising:
receiving a request to activate a grid;
receiving, from an input device, a request to place at least one edge of a shape at a location on the grid; and
automatically placing the at least one edge of the shape in a pre-defined area of the grid when the location of the request is within a threshold position of the pre-defined area.
2. The method of claim 1 , further comprising receiving a user selection of the shape before activating the grid.
3. The method of claim 2 , further comprising:
copying the shape; and
placing the copied shape on the grid.
4. The method of claim 3 , wherein edges of the shape are placed in pre-defined positions within the pre-defined area.
5. The method of claim 2 , further comprising moving the shape from a first location to the pre-defined area.
6. The method of claim 5 , wherein moving the shape from the first location to the pre-defined area comprises placing edges of the shape in pre-defined positions within the pre-defined area.
7. The method of claim 1 , wherein pre-defined rules for automatically placing the at least one edge of the shape in a pre-defined area of the grid are based on a standard cell architecture.
8. The method of claim 7 , wherein the pre-defined rules include pre-defined grid coordinates.
9. The method of claim 8 , further comprising applying coordinates defined in the pre-defined grid coordinates to each shape.
10. The method of claim 7 , wherein the grid allows for stretching each edge of the shape to a plurality of allowed positions.
11. The method of claim 1 , wherein the shape is a new shape that is created and placed on the grid.
12. The method of claim 11 , further comprising selecting a layer of the grid when the new shape is created.
13. The method of claim 12 , further comprising placing edges of the new shape in pre-defined positions within the pre-defined area.
14. The method of claim 1 , further comprising displaying only one or more allowed positions for the shape.
15. The method of claim 1 , wherein the pre-defined area is based on pre-defined rules described in an architecture file.
16. The method of claim 15 , wherein grid values are included in the architecture file.
17. The method of claim 16 , wherein the grid values include centering attributes for different layers of the grid.
18. The method of claim 16 , wherein the grid values include edge attributes for the shape.
19. A non-transitory computer-readable medium having stored thereon a plurality of computer-executable instructions which, when executed by a computer, cause the computer to:
receive a request to activate a grid;
receive, from an input device, a request to place at least one edge of a shape at a location on the grid; and
automatically place the at least one edge of the shape in a pre-defined area of the grid when the location of the request is within a threshold position of the pre-defined area.
20. A device, comprising:
a computer system having a processor and a memory having stored thereon a plurality of executable instructions which, when executed by the processor, cause the processor to:
receive a request to activate a grid;
receive, from an input device, a request to place at least one edge of a shape at a location on the grid; and
automatically place the at least one edge of the shape in a pre-defined area of the grid when the location of the request is within a threshold position of the pre-defined area.
