Hello Guenter Roeck: I still shall try qemu and kernel distribution, next, since it can do it successfully (whether 'sim' can be success or not).
But excuse me, maybe I can not finish microblaze qemu test within this month, hope I can finish within next month (2014-11-30). Thank your information about qemu, again. Thanks.
