Software validation for FPGA

Morning,

I heard there is some unclear about software validation for system that use FPGA. I don't know the general opinion on that, and what would be the implication if manufacturers use multiple MCUs and CPLDs instead of FPGA?

Thx,

My experience has been that is is typically the case that an FPGA is programmed to behave as a specific device (that is, the FPGA isn't "executing code" like a processor), and so aside from exercising revision control (i.e. configuration management) over what is 'installed' in an FPGA as well as the physical part, the programmed FPGA can be evaluated like any other component... that is: does the device behave as required/expected?

If the FPGA is going to act more like a processor, then perhaps a more detailed assessment of how well that code meets its intended use is required.

There are subtleties within different industries, of course.
