Internal Timing Parameters
Internal timing parameters are specified on a speed grade basis
independent of device density.
MAX II device internal timing microparameters for logic elements (LEs),
input/output elements (IOEs), UFM structures, and MultiTrack
interconnects. The timing values for –3, –4, and –5 speed grades shown in
Tables 5–15
–6 and –7 speed grade values are based on an EPM570Z device target.
For more explanations and descriptions about each internal timing
microparameters symbol, refer to the
