Try to understand Hierarchical Partial Reconfiguration(HPR)

@sstrell

Thanks for the reply. I understand your point. But I want to have some flexibility of using parent1 with a large single PR region or two smaller PR regions.

As you said, once we've established LL regions for children, we can't remove them.

So how about the flow below? The idea is to have one static qdb for a level-1(for parents) and another static qdb for a level-2(for children).

And when we want to use a large single PR region, use static_lvl_1.qdb (bit1 in the example below).

When we want to use two single PR regions, use static_lvl_2.qdb (bit2_1 and bit2_2 in the example below).

My question is, are bit1 and bit2_1/bit_2_2 compatible?

My guess is that static_lvl_2.qdb should have all those fixed placement and routing info from static_lvl_1.qdb. So maybe they are compatible... but I am not sure.
