Which company has done ARM development right?

schendel_nsf, you really did not say anything derogatory but people are hypersensitive these days (at least in the US) and I just wanted to make sure I did imply the manager had said anything derogatory.

The PolarFire is an impressive chip that puts Cyclone V to shame, but I don't think there is a SoC version. And the price is very high.

The Microsemi SoC is the SmartFusion2. I tried it out. The tools are poor and the support is so bad (ie none, not even a poorly designed forum like this one) it makes Altera look good. The compile times are very long (I think they only use one processor). Again, this is four year old information, so things could have changed.

When it comes to SoC FPGA, it's pretty much Altera and Xilinx. And unless you are using Linux for a data center application, it's basically Xilinx.

When it comes to non SoC FPGA's, we're taking a wait and see. Based on talks from their CEO, I suspect MAX 10 and Cyclone V are the end of the road for that level chip and Intel will only do high end data center chips. Hopefully I'm wrong (what do I know), but Lattice and Microsemi provide viable alternatives. All these chips (MAX 10, Cyclone V, Lattice ECP5) are several years old at this point.
