Ncd, Ngm | Xilinx 8.2i specification

NCD

A Native Circuit Description (NCD). The physical database format for

Xilinx Implementation software tools.

net

A logical connection between two or more symbol instance pins. After routing, the abstract concept of a net is transformed to a physical connection called a wire.

An electrical connection between components or nets. It can also be a connection from a single component. It is the same as a wire or a signal.

netlist

A netlist is a text description of the circuit connectivity. It is basically a list of connectors, a list of instances, and, for each instance, a list of the signals connected to the instance terminals. In addition, the netlist contains attribute information.

network

A network is a collection of logic elements and the wires (nets or connections) that define how they interconnect.

NetGen

A program that reads in applicable Xilinx implementation files, extracts design data, and generates netlists that are used with supported third-party simulation, equivalence checking, and static timing analysis tools.

NGDBuild

A program that converts all input design netlists and then writes the results into a single merged file.

NGM

A design file produced by MAP that contains information about the logical design and information about how the logical design corresponds to the physical design.

optimization

Optimization is the process that decreases the area or increases the speed of a design.
