Abstract
A method of performing virtual connectivity change between first and second nets associated with an integrated circuit is presented. The method includes generating a first top view and a first perspective views of a layout of the integrated circuit when a computer is invoked to perform the virtual connectivity change. The method further includes defining layers associated with the first and second nets, and defining a boundary of the virtual connectivity change. The method further includes performing the virtual connectivity change between the first and second nets within the boundary, and generating a second top view and a second perspective view of the layout of the integrated circuit after the virtual connectivity change.
Claims10
A method comprising:
- performing a trace to highlight polygons of an input net when a computer is invoked to perform the trace;
- processing the polygons marked by edit boxes by a user;
- processing the net traced polygons as constrained by top and bottom layers set for the edit boxes;
- ending net tracing at the edit boxes having a cut type;
- and
- identifying an overlapping net on the edit boxes having a deposit type.
A computing apparatus, the computing apparatus comprising:
- a processor;
- and
- a memory storing instructions that, when executed by the processor, configure the apparatus to:
- perform a trace to highlight polygons of an input net;
- process the polygons marked by edit boxes by a user;
- process net trace polygons as constrained by top and bottom layers set for the edit boxes;
- end net tracing at the edit boxes having a cut type;
- and
- identify an overlapping net on the edit boxes having a deposit type.
