Performance
The maximum internal logic array clock tree frequency is limited to the
specifications shown in
Table 4–19
.
Table 4–20
shows the Cyclone device performance for some common
designs. All performance values were obtained with the Quartus II
software compilation of library of parameterized modules (LPM)
functions or megafunctions. These performance values are based on
EP1C6 devices in 144-pin TQFP packages.
