Logilock and design partition difference?

[Altera_Forum]

Hi, 

can someone point out the difference between them? I don't understand. Both of them make some sort of 'partition' to the block. Logilock kinda locks it while partition do what? I know it's for incremental compilation, but what's the difference between them? Thx.

LogicLock physically places it in the device based on the rectangle(or other shape) you create. Partitions have the hierarchy synthesized independently of other logic(although it is fit with the rest of the design as if they were flat, at least on the first pass). You then have the option to re-use the previous synthesis of that hierarchy or synthesis and fit information on your next compile. The Quartus II handbook should talk about it quite a bit.

Thank you very much.

This answer keeps the same ideology as User Guides - not to explaining what exactly the difference. They say LogicLock can limit rectangle but they don't say partition cant. They say partitions can synthesize independently but they don't say LogicLock can't. Looks like nobody has clear and easy answer to this question.
