6 years agoHi sstrell,
I am using the standard edition. I have been trying to use the incremental compilation but it it did not work. I exported the post-fit partition for sub circuit B. When I tried to import it to two different partitions in circuit A, it failed because the post-fit net-list preserves all the placement info including where to place each logic of B. Then two different partitions of B in circuit A will share the same location and I can not change it, which cause conflict. Do you have any idea on how to work around this?
Thank you so much!
