3.3i Foundation ISE Project Importer - Schematics containing similar bus and pin names cause synthesis errors
説明
Keywords: ISE, Project Navigator, Project Importer
Urgency: Standard
General Description: If a bus pin on a schematic symbol and a single net pin on the same symbol have the same root name, a problem occurs when the VHDL netlist is generated from the schematic, and synthesis will fail.
Example: A symbol with bus pin "c[7:0]" and clock pin is simply named "c." This works successfully through schematic flow, but the VHDL netlist will cause an error.
ソリューション
The signal pin or bus pin must be renamed. This can be done in the schematic, or in the resulting VHDL structural netlist
