    Virtex (Large Device) Design Methodology using LeonardoSpectrum 1999.1
  • pdf Using Xilinx and Exemplar for Incremental Designing (ECO)Internet Link
    Guided place and route (PAR) can help you reduce runtimes when incremental changes are made to a design, such as for an Engineering Change Order (ECO). By making only small changes to a design along with optimizing only the changed block(s), you allow guided PAR to perform at its best, preserving timing and reducing PAR runtimes. To localize the design changes without affecting the remainder of your design, either a top-down preserving hierarchy or a bottom-up methodology must be used.
