Cyclone V SE SoC FPGA ARM HPS - also with Nios2 buried in FPGA?

For the date, contact your sales rep.

You could get started on the soft logic side and work your way up to the HPS block. Using Nios II in a SoC device is no different than a standard FPGA. In fact Nios II has no concept of a SoC vs a non-SoC FPGA so if you are an existing Nios II user you won't notice anything different to what you are already accustom to doing.
