Preliminary

Timing Model

Internal Timing Parameters

Internal timing parameters are specified on a speed grade basis

independent of device density. Tables 4–21 through 4–24 describe the

Cyclone device internal timing microparameters for LEs, IOEs, M4K

memory structures, and MultiTrack interconnects.
