The continuous, high-performance FastTrack Interconnect routing
structure ensures 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.
