Timing Model
One important feature of the Delta39K family is the simplicity
of its timing. All combinatorial and registered/synchronous de-
lays are worst case and system performance is static (as
shown in the AC specs section) as long as data is routed
through the same horizontal and vertical channels. Figure 10
illustrates the true timing model for the 200-MHz devices. For
synchronous clocking of macrocells, a delay is incurred from
macrocell clock to macrocell clock of separate Logic Blocks
within the same cluster, as well as separate Logic Blocks with-
in different clusters. This is respectively shown as tSCS and
tSCS2 in Figure 10. For combinatorial paths, any input to any
output (from corner to corner on the device), incurs a worst-
case delay in the 39K100 regardless of the amount of logic or
which horizontal and vertical channels are used. This is the tPD
shown in Figure 10. For synchronous systems, the input set-
up time to the output macrocell register and the clock to output
time are shown as the parameters tMCS and tMCCO shown in
the Figure 10. These measurements are for any output and
synchronous clock, regardless of the logic placement.
The Delta39K features:
no dedicated vs. I/O pin delays
no penalty for using 0–16 product terms
no added delay for steering product terms
no added delay for sharing product terms
no output bypass delays
The simple timing model of the Delta39K family eliminates un-
expected performance penalties.
