Regardless of the market segment your product targets you are being required to build it with the lowest power operation to either compete, differentiate or just be more green. This week I ran into a customer who unfortunately had to re-spin their chip due to a low power mode of operation issue. The software was able to put the chip into a low power mode but due to a bug, they were unable to get the chip out of the low power mode cleanly without a system reset. This customer wanted to better verify the low power modes before tape-out this time around.
Ultimately when you hand-off your physical FPGA-based prototype to the end users there are only two things that they care about; Performance, Performance, Performance. I know I said there were only two things but performance is so important I listed it three times.
