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 ...

Hi,Jack,

The maximum current is 24mA,I am sure.

I just suppose that I use all I/O pin to source/sink the same current(20mA,for example).The amount of current actually drawn by the I/O pin depends on what you've got connected to it,you are right.And I suppose in my curcuit the current is 20mA.The problem is,if I use many pins in this way,the sum of the current count be great,and I wonder if the FPGA would damage.
