Within Quartus II the design is elaborated and analyzed, and the LogicLock blocks are imported. The design is compiled with the LogicLock constraints back-annotated to the design. The designer may make incremental changes to the design, and re-import blocks as needed. The design is then re-compiled. This flow is followed until the designer is satisfied with the final product.


	Now we discuss the LogicLock design flow. Within Precision Synthesis, the LogicLock attribute is applied to a block in the design. The design is then synthesized. The output may consist of multiple EDIF and Tcl files.
