3.1i Foundation ISE: The source netlist for "xxx.ngo" was not found
Keywords: Foundation ISE, Project Navigator, ECS, ngdbuild
When a schematic design is implemented in ECS, ngdbuild issues messages like the following on Xilinx Unified Library macros:
Launcher: The source netlist for "ADSU16.ngo" was not found; the current NGO file will be used and no new NGO description will be compiled. This probably means that the source netlist was moved or deleted.
All Xilinx Unified Library macros are treated as black boxes by the synthesis tools. The implementation models for these components is a NGO file. When Ngdbuild is run the NGO files are included to properly implement the design.
