i have got sch/brd files of xilinx VCU118 dev kit.
since i do not know how to cross probe from DxD to allegro, i have translated DxD (viewdraw) schematic to dsn.
the brd file can be open by allegro 16.6 without any drc problem. but if i import logic from the tanslated orcad generated netlist,
thousands of drc errors would occur. the translation is problematic, to say the least.
so i want to backannotate from this brd file to the translated orcad dsn. normally, backannotate means you have synchronized
from orcad to allegro before, but i didn't ever.
hope i have made myself clear.
