Spacecraft Multicore Emulator Based on Leon 3 Sparc V8 Architecture Processor (github.com/kmonahopoulos)

The target is, of course, Gaisler's SPARCv8 LEON3, as designed for ESA. The LEON processors are interesting because they include a lot of radiation-hardening, which is essential for computers running outside the (protective) atmosphere.

Gaisler also sells TSIM (which aims for cycle-by-cycle accurate simulation of Gaisler's chips). Since I see that the author of this software has submitted it to HN: why would I use this software instead of TSIM? You obviously had a reason!

LICENCE.txt is somewhat confusing; 4-clause BSD isn't bad, per se, but it's not entirely clear whether Monahopoulos Konstantinos or EMTech is the copyright holder. Also, from a practical perspective, "This product includes software developed by the EMTech." is probably false - I'd expect emulators to be used during development and test, not during the actual mission?

The README mentions an associated "paper"; it would be great to include a link.
