The configuration for Example 2 is:
- BPI (x16) Synchronous mode, operating at 50 MHz ± 100 ppm
- Stage 1 size = 11822112 bits = 11.27 Mb
The steps to calculate the configuration loading time are:
- Calculate the minimum clock frequency:50 MHz × (1 - 0.0001) = 49.995 MHz
- Calculate the minimum PROM bandwidth:16 bits × 49.995 MHz = 799.92 Mb/s
- Calculate the first-stage bitstream loading time:11.27 Mb / 799.92 Mb/s = ~0.0141 s or 14.1 ms
