Abstract
In a particular embodiment, a method is disclosed that includes detecting a first pitch between at least two lines (e.g. a power line and a ground line) of a first reference macro. The method also includes generating a virtual grid based on the first pitch and aligning at least a second macro to the virtual grid.
Claims25
A method comprising:
- detecting a first pitch between at least two lines of a first reference macro;
- generating a virtual grid based on the first pitch;
- and
- aligning at least a second macro to the virtual grid.
1 more element
A processor-readable medium containing processor executable instructions that are operative to cause the processor to:
- designate a macro cell of a plurality of macro cells of an integrated circuit design as a reference macro;
- determine one or more parameters of the reference macro;
- automatically generate a virtual grid of power lines and ground lines based on the one or more parameters of the reference macro;
- and
- automatically align at least one other macro cell to the virtual grid.
2 more elements
A method comprising:
- determining one or more parameters of a reference macro, wherein the reference macro is a macro cell of an integrated circuit design;
- generating a virtual grid based upon the one or more parameters of the reference macro;
- calculating a displacement and detecting an orientation of one or more other macro cells of the integrated circuit design relative to the virtual grid;
- and
- aligning the one or more other macro cells to the virtual grid based on the calculated displacement and the detected orientation.
2 more elements
An integrated circuit design tool comprising:
- a processor;
- a memory coupled to the processor, the memory storing macro cell power grid alignment instructions that are executable to cause the processor to:
- designate a macro cell of a plurality of macro cells of an integrated circuit design as a reference macro;
- determine one or more parameters of the reference macro;
- automatically generate a virtual grid of power lines and ground lines based on the one or more parameters of the reference macro;
- and
- automatically align at least one other macro cell to the virtual grid.
