The configuration for Example 2 is:
• BPI (x16) Synchronous mode, operating at 50 MHz ± 100 ppm
• Stage 1 size = 9175424 bits = 8.75 Mb
The steps to calculate the configuration loading time are:
1. Calculate the minimum clock frequency:
50 MHz × (1 - 0.0001) = 49.995 MHz
2. Calculate the minimum PROM bandwidth:
16 bits × 49.995 MHz = 799.92 Mb/s
3. Calculate the first-stage bitstream loading time:
8.75 Mb / 799.92 Mb/s = ~0.0109 s or 10.9 ms
