Bottom-Up LogicLock-Based Design
Flow
In the bottom-up block-based LogicLock design flow, you can design and
optimize each module independently, integrate all optimized modules in a
top-level design, and then verify the overall design. Each module has a
separate netlist, which can then be incorporated after synthesis and
optimization into the top-level design. Each module in the top-level design
does not affect the performance of the other modules. The general block-
based design flow concepts can be used in modular, hierarchical,
incremental, and team-based design flows.
You can apply LogicLock constraints to individual nodes as well as to
hierarchical blocks; for example, you can make a wildcard path-based
LogicLock assignment on a critical path, which may be useful if the critical
path spans multiple design blocks.
You can use EDA design entry and synthesis tools in the block-based design
flow to design and synthesize individual modules, and then incorporate the
modules into a top-level design in the Quartus II software, or completely
design and synthesize a block-based design in EDA design entry and
synthesis tools. For more information on the block-based design flow, refer
to “Chapter 6: Block-Based Design” on page 113.
