Density Shifting
The MachXO family has been designed to enable density migration in the same package. Furthermore, the archi-
tecture ensures a high success rate when performing design migration from lower density parts to higher density
parts. In many cases, it is also possible to shift a lower utilization design targeted for a high-density device to a
lower density device. However, the exact details of the final resource utilization will impact the likely success in
each case.
