In 2003, Xilinx was saying higher static power was an inevitable price
of progress, and that speed was king, and nothing was on the Horizon
to solve this.....
It is interesting to read this latest press release
http://www.xilinx.com/prs_rls/silicon_vir/0470umc_tripleoxide.htm
"By using three different thicknesses of the insulating gate oxide
layers, the companies were able to break the traditional tradeoff
between power consumption and performance, and expect to lower static
and dynamic power consumption by 50 percent from previous generation
devices with the Virtex-4 platform FPGA family."
Some real numbers would be nice : Just where are we now (V4 samples),
on the static power spectrum ?
'50 percent' is not great, but is much better than another step in the
wrong direction
and also this, which is more on the horizon @ 65nm:

seems the foundries/R&D are very aware of the importance of static Icc
in many applications, and they are working to tune the process to allow
designer selection.
Cutting edge silcon EDA tools now talk about 'power closure', in the
same way timing closure was the hot button a couple of years ago.
