An automated method of modifying a semiconductor chip design includes creating a timing analysis of said semiconductor chip design, identifying a plurality of gates in said semiconductor chip design which have either too fast a rising edge or falling edge, for each gate in said plurality of gates adding a stacked transistor to provide delay to the rising or falling edge of the gate. A design structure tangibly embodied in a machine readable medium for designing, manufacturing, or testing an integrated circuit, the design structure includes a CMOS device having a first transistor with a first input, a pair of stacked transistors having a second input, and an output.

A topology of a multitier compute infrastructure is automatically discovered. Discovery can be roughly divided into two phases. In one phase, components and physical relationships are discovered. In the other phase, non-physical relationships between the components are deduced. The second phase typically is based in part on information obtained in the first phase. In one application, the components and relationships that are discovered/deduced are used to build a map of the multitier compute infrastructure.

Automated discovery of a multitier compute infrastructure

A multitier topology map describes a multitier compute infrastructure. The multitier topology map identifies components from at least two different tiers of the multitier compute infrastructure and indicates relationships between components including at least one cross-tier relationship between components. An interface module accesses the multitier topology map.

A descriptor for a multitier compute infrastructure is provided. A multitier topology map contains an inventory of network tier, application tier, and compute tier components and the relationships among the components. A business service can be defined as a logical grouping of components that transactionally implement a business process. A service descriptor includes the component dependencies that define the business service. The business service leverages the component dependencies to provide cross-tier visibility of the business process and performance analysis features.

An application model automates deployment of an application. In one embodiment, the application model includes a static description of the application and a run-time description of the application. Deployment phases, such as installation, configuration and activation of the application are executed according to the application model.
