Logic and Routing – Look-Up Tables (LUTs) Combinational logic is stored in Look-up Tables (LU
Ts) in a CLB. Capacity is limited by number of inputs, not complex
ity. Delay through CLB is constant.

Map Property Trim Unconnected Signals
If you check this item, the mapping tool will remove the unconnected wire that let the tracing back become hardly.
Generate Detailed Map Report If more detailed report is needed, you can check it. (Recommending ch
eck it) Use Guide Design File (.ncd)
You can refer the last mapping solution so that you maybe get better solution.
Use RLOC Constraints Constraints of CLB (default check).
Pack I/O Registers/Latches into IOBs If the value chosen Default that pack the register nearby I/O into I/O blo
ck. You can also chose only for input or only for output or off.

Place and Route Property (1/2) Place & Route Effort Level (Overall)
Effort Level means the P&R effect result. Using the Higher get the better solution, but spend more time.
Starting Placer Cost Table (0-100) Specify a placement initialization value with which to begin P&R attem
pts. Each subsequent attempt is assigned an incremental value based on the placement initialization value.
Place and Route Mode Quick means without timing constraints; Route Only and Re-entrant Ro
ute mean P&R must have been run at last once to use this option.
