But leon2 is supposed to work on qemu and apparently leon3 now does.
I personally haven't tried it but Sebastian appears to have had luck.

Here's what I know about sparc simulators for our BSPs.

gdb sis - (free) erc32
tsim - (paid) erc32, leon2, leon3
grsim - (paid) leon3, leon4, ngmp
qemu - (free) leon2, leon3

I would love to see instructions for qemu on leon2 and leon3.
It would be awesome as we bring the buildbot online.
