Timing Model
The task of determining the timing through the ispMACH 4000ZE family, like any CPLD, is relatively simple. The
timing model provided in Figure 16 shows the specific delay paths. Once the implementation of a given function is
determined either conceptually or from the software report file, the delay path of the function can easily be deter-
mined from the timing model. The Lattice design tools report the timing delays based on the same timing model for
a particular design. Note that the internal timing parameters are given for reference only, and are not tested. The
external timing parameters are tested and guaranteed for every device. For more information on the timing model
and usage, refer to TN1168,
