Hi, I got the following Error when I tried to open my top level QSYS design: Error: An unexpected error occurred during Open System: java.lang.NullPointerException Debug: java.lang.NullPointerException

I have a top level QSYS with two QSYSes included. When I tried to rename some of the internal QSYS export ports, I got this error in the top-level QSYS.

I use 18.1.0.222 Quartus version.

How do I fix it?

Thanks,

What OS that you were using?

check if you have any linked 'disabled' components in the system - if yes, try to delete rather than disable the components then system builder.

any update?

Hi,

I work with CentoOS 6.7/6.9

Thanks,

Have you try the suggestion above? If yes, what is the result?

Thanks! After I removed the disabled components it works!

Good to hear that!
