“Register Ordering”

“Guided Mapping”

“Simulating Map Results”

“MAP Report (MRP) File”

“Halting MAP”

MAP Overview

The MAP program maps a logical design to a Xilinx FPGA. The input to MAP is an NGD file, which is generated using the NGDBuild program. The NGD file contains a logical description of the design that includes both the hierarchical components used to develop the design and the lower level Xilinx primitives. The NGD file also contains any number of NMC (macro library) files, each of which contains the definition of a physical macro.

MAP first performs a logical DRC (Design Rule Check) on the design in the NGD file. MAP then maps the design logic to the components (logic cells, I/O cells, and other components) in the target Xilinx FPGA.
