Cyclone 10 GX Configuration Time

[HamzahS]

Hi,

We have a custom made PCB with a Cyclone 10 GX FPGA that uses ASx4 configuration scheme. Everything works fine except the boot (FPGA entering User Mode) time. It's too long to pass our requirements. It takes around:

1- Fast POR: 220 ms

2- Standard POR: 360 ms

We would like to get it under 100 ms even if it gets to changing design and configuration scheme.

Kindly advise on whether this is possible or not, and how.

Thanks,

-Sulaiman

You may refer to cyclone 10 gx for the estimated configuration time for every configuration scheme.

You might need to consider PS configuration scheme if you are looking for time with less than 100 ms.

Could this be done without using another FPGA or CPLD?

For PS configuration, you need a CPLD or a processor for that.
