Contributor22.1 PRO: (*preserve_for_debug*) signals not preserved
Hello,
Alright thanks for the feedback. I've let them know that you expect this fix to apply to all data types.
In the meantime your only workaround is to have the signal connected to an i/o port.
With that, I now transition this thread to community support. If you have a new question, feel free to open a new thread to get the support from Intel experts. Otherwise, the community users will continue to help you on this thread. Thank you.
Regards,
Nurina

Super ContributorIf it's not going to get connected to anything, that's not what preserve for debug is for. Instead, add a virtual pin assignment to the node. Preserve for debug is to preserve internal nodes through the compilation and optimization process, maintaining their names so they can be easily added to post-fit debugging tools like Signal Tap. Virtual pins are logic stubs created to prevent I/O from getting optimized away.
