Preserve for Debug Command (Context Menu) (Platform Designer)
Right-click on module, interface, or port names in the Platform Designer
System View or Filter tab to mark signals for
preservation through synthesis and fitting for later use in debugging.
The command marks the signals to prevent synthesis from performing optimizations on specific module, interface, and port names, allowing the names to persist into the post-fit netlist for Signal Tap and other debug monitoring. A green "P" icon indicates that the preservation applies.
