MAX 9000 Programmable Logic Device Family Data Sheet
The continuous, high-performance FastTrack Interconnect ensures
Timing Model
predictable performance and accurate simulation and timing analysis.
This predictable performance contrasts with that of FPGAs, which use a
segmented connection scheme and hence have unpredictable
performance. Timing simulation and delay prediction are available with
the MAX+PLUS II Simulator and Timing Analyzer, or with industry-
standard EDA tools. The Simulator offers both pre-synthesis functional
simulation to evaluate logic design accuracy and post-synthesis timing
simulation with 0.1-ns resolution. The Timing Analyzer provides point-
to-point timing delay information, setup and hold time prediction, and
device-wide performance analysis.
The MAX 9000 timing model in Figure 14 shows the delays that
correspond to various paths and functions in the circuit. This model
contains three distinct parts: the macrocell, IOC, and interconnect,
including the row and column FastTrack Interconnect and LAB local array
paths. Each parameter shown in Figure 14 is expressed as a worst-case
value in the internal timing characteristics tables in this data sheet. Hand-
calculations that use the MAX 9000 timing model and these timing
parameters can be used to estimate MAX 9000 device performance.

Application Note 77 (Understanding MAX 9000 Timing).
