Interesting, although I was more thinking about FPGA's in things like acquisition and processing rather than overall logic as the PC seemed to imply.

The high level NASA requirements cast a pretty wide net (to include data acquisition and processing) as to what falls under the purview of those requirements. From 7150.2:

“ A.30 Software. Computer programs, procedures, scripts, rules, and associated documentation and data pertaining to the development and operation of a computer system. Software includes programs and data. This also includes COTS, GOTS, MOTS, reused software, auto generated code, embedded software, firmware, and open source software components.”
