STRATIX10 Configuration time

Hi, I'm planning to use the STRAIX 10 GX 2800 (H-Tile) FPGA. I have a question regarding the ASx4 & SD configuration time (there are a few contradictions in the data sheet). The dataseet...

Hello, the AS clock and the SD clock (133MHz, 50Mhz) are the clock provided to the external flash (EPCQ and SDCard). Meanwhile, the SDM block in Stratix 10 requires a separate clock to itself (it can be an internal oscillator or dedicated external clock of 250MHz)

Therefore, both of these will impact the configuration time. Currently configuration using AS is faster than SDMMC in all circumstances
