APEX 20K Programmable Logic Device Family Data Sheet
Preliminary Information
Timing Model
The continuous, high-performance FastTrack Interconnect routing
resources ensure predictable performance and accurate simulation and
timing analysis. This predictable performance contrasts with that of
FPGAs, which use a segmented connection scheme and therefore have
unpredictable performance.
Timing simulation and delay prediction are available with the Quartus
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 1-ps
resolution. The Timing Analyzer provides point-to-point timing delay
information, setup and hold time analysis, and device-wide performance
analysis. Figure 36 shows the timing model for bidirectional I/O pin
timing.
Figure 36. Synchronous Bidirectional Pin External Timing Model
Tables 19 and 20 define the I/O timing parameters for APEX 20K devices.
Tables 21 through 26, show the I/O timing parameter values for
APEX 20K devices.
