    Derating Timing Tables
    Logic Timing provided in the following sections of the data sheet and the ispLEVER design tools are worst-case
    numbers in the operating range. Actual delays at nominal temperature and voltage for best-case process, can be
    much better than the values given in the tables. To calculate logic timing numbers at a particular temperature and
    voltage multiply the noted numbers with the derating factors provided below.
    The junction temperature for the FPGA depends on the power dissipation by the device, the package thermal char-
    acteristics (
    Θ
    JA
    ), and the ambient temperature, as calculated with the following equation:
    T
    JMAX
    = T
    AMAX
    + (Power *
    Θ
    JA
    )
    The user must determine this temperature and then use it to determine the derating factor based on the following
    derating tables: T
    J
    °C.
