I have an ISE project with an EDK project as a submodule.
The peripheral was created using the Create and Import Peripheral Wizard. After that, I added some ports to the IP core and made them external to the EDK project.
When I run the implementation of the design, NGDBuild gives the following error:
"ERROR:NgdBuild:809 - output pad net 'Bus2IP_BE<0>' has an illegal load"
How do I overcome this error?
1. Make a copy of "system.make" to "user_system.make".
2. Search for the line where the makefile launches PlatGen.
3. Add a switch -toplevel no to the PlatGen command line.
4. In Project > Project Options, specify the custom makefile field and point to "user_system.make".
