Power dissipation of design without any logic

[Altera_Forum]

A design without any logic is compiled and analysed in PowerPlay Tool,the result as below, 

Core dynamic thermal power dissipation: 0mw Core static thermal power dissipation: 79.98mw I/O thermal power dissipation: 30.07mw   Is static dissipation too much high for Ep2c35? Why in a no logic design still exist I/O dissipation? Thank you!

Well, to start with, there is a thing called a leakage current ;)
