How much is the maximum current of FPGA

Hi,everyone, I'm working in a project using EP1C6Q240.The datasheet says that the Current Strength of each I/O pin can be set up to 24mA.Suppose I use 100 pins to output 20mA at the same time,the ...

You can also perform advanced I/O analysis where you state specifically what the loading on the pins are. This enables Quartus to warn you of any problems.

Are you driving LEDs with the pins? What I typically recommend is that you drive LEDs through a standard LVTTL or LVCMOS buffer (like a 74LVT244 for example). It's not worth risking damage to your FPGA.

What are you doing that has such a high current requirement on the pin?
