In-production with Nios/uCLinux?

in my mind, fpgas aren't as stable as lets say off-the-shelf processors. for example, there are problems on configuration sometimes from powerup, so you have to accunt for that in circuitry (crc checking). also, i have had problems with the avalon fabric itself locking up, so that has reduced my trust in fpgas. these are just a few of the issues. also, i haven't subjected them to temperature variations, so that's a big q-mark for me.

Oh Ok.

Regarding to temperature issues, I developped many FPGA design for my company, and each time we had to subject them to temperature variations (-30 °C/+70°C). And believe me, if your design is well coded (fully synchronous especially ), it works.

Regarding to avalon fabric bug. What can be said ? ASIC are also prone to mask bug. With an ASIC , you have to wait for a new mask. With an FPGA you have to wait for a new design. So...

By the way, what other issues do you talk about ?
