Honored ContributorCyclone V vs Cyclone IV static power
From Quartus compilation I see that:
EP4CE115F29C7 115k LE typical 98.46 mW max 130.41 mW 5CEBA5U19C7 77k LE typical 227.17 mW max 322.46 mW But... Cyc V shouldn't be 40% lower static power????14 Replies
Altera_ForumI used an 8 bit unsigned adder to test static power. I see that Cyclone V is very power hungry instead marketing say that is lower power... :(
Here other data.. http://www.alteraforum.com/forum/attachment.php?attachmentid=10843&stc=1- Altera_Forum
I believe the up to 40% lower power than Cyclone IV is referring to the information advertised at https://www.altera.com/products/fpga/cyclone-series/cyclone-v/overview.html.

Mind share with me on the 40% lower static power? Is it extract from the Altera web? By the way, you can use early power estimator to double check on this by just select the device without enable any logic to see if the 40% lower is refer to intrinsic power consumption without power up.

Hi,
Just to clarify if the same design file with the same logic turn on in both EP4CE115F29C7 and 5CEBA5U19C7 during compilation. Are you referring EPE spreadsheet?
