During the Compile process, Designer checks the netlist properties. If the netlist file specifies a pin assignment for a pin that was also assigned in PinEditor session, there is a conflict. How this conflict is resolved is determined by your selection in this check box.
If this option is Off, or cleared, then Designer uses the assignment made in PinEditor, and the assignment in the netlist file for the conflicting pin is ignored. If this option is On, or selected, then Designer uses the assignment in the netlist file for that pin, and the PinEditor assignment is ignored. If you edit pin assignments in PinEditor, this option is automatically set to Off.
Use the control slider in the Messages area to control the warning level. Use the control slider to specify the fanout limit that the Compile step checks against. Setting the control slider to '0' informs the system to use the system defaults. Any non-zero value replaces the system default value for the fanout limit with the user-specified value. Typically, this value range is 1 to 24.
This does not adjust the fanout of the design and it has no effect on the netlist. This only adjusts the warning level by controlling what level of fanout checking you want to be warned about during Compile. Changing this fanout limit option does not invalidate the Compile design state.
