soc encounter hierarch

Hi,
I am new to this cadence tool. I am confused what is "partition" in it? I have divided my design into several sub-modules in verilog netlist after design compiler's synthesis. Do I still need to do partition in SOC encounter?

Thanks!!

Hi eexuke:

It's depend on whether the logic hierarchy consistent with your physical

hierarchy. Normally, it's a difficult work.

It's hard to compare these two tools, because both of them will get better

result of some aspect(Timing is only one aspect).

But if you use Astro you will have to use Jupiter if you wanna do hierachy

floorplan, if you use Encounter, no more hierachy floorplanner is needed.

You have to think about it when your gate counters are large.

If your design is too large, please divided it. SOC encounter only support a way to do partition. Normally, do not divide a chip less 1M gates to some blocks. It will increase difficults to P&R.

SOC Encouter is better for hierarchical p&r. And I heared that it is very fast.At same time it is very expensive.:(
