Newbie: Slow FPGAs

There is also a cost advantage with fpgas until you get into high volumes. The fact of the matter is FPGAs are on 90nm technology now, and will compete head to head with ASIC on a 0.25 micron fab. Most ASIC starts can get away with less than bleeding edge geometries, so that will tend to lessen the gap between the performance of an FPGA vs performance of an ASIC done with the coarsest geometry that wil get the job done.

Thanks. Your reply follows the general theme of others: FPGA speeds are sufficiently high, it is the design of FPGA technologies that can sometimes result in what might appear slow performance, but in fact this is the generic FPGA functionality at work.

I (inappropriately) was complaining about why "one size fits all" FPGA devices did not meet my specific requirements. Stupid now I consider it and the flames will continue to burn me for a while!!
