In one aspect, a technique for performing signal activity extraction in an integrated circuit an integrated circuit is described. The integrated circuit includes multiple nodes. The technique includes compiling a design of the integrated circuit, estimating signal activities at the nodes, determining a node of interest from the nodes, and connecting a signal activity circuit to the node of interest. The determination of the node of interest and the connection of the signal activity circuit to the node of interest first compared to the remaining nodes of the integrated circuit improves efficiency in determining nodes of the integrated circuit at which signals can be analyzed first. Such signal activity extraction may involve power analysis and power optimization.

Methods and systems for performing signal activity extraction

A graphical block-based design exploration tool displays multiple views of a chip design. These views may include a logical view, physical view, hierarchy view, and a timing display view, displayed side-by-side or sequentially with or without animation. Various entities and their relationships to each other are displayed in these different view arrangements to allow a user to quickly grasp the entire design and to perform design techniques such as partitioning and floor planning. The display properties are user configurable to organize the information based on user preferences.

Graphical block-based design exploration tool

A method for positioning components of a system onto a target device utilizing programmable logic devices (PLDs) is disclosed. A first location on the target device for a first logic region having a first component is determined. Determined properties of the first logic region are preserved. The first logic region is integrated with a second logic region having a second component in view of the determined properties.
