I need a software who emulate SPARC system (Hardware) in a Windows 7 host computer. I need to install a Solaris SPARC 10 for developing purpose and I don't have a SPARC machine.
Can you give me some advice?
You're likely to have only one option as far as sparc emulation on windows 7 goes - QEMU - which is the only common emulator supporting dissimilar architectures.
If it works, it'll likely to be MUCH slower than a real system , and apparently it dosen't work yet
If Solaris 8 is acceptable, you might want to evaluate sybil: http://www.stromasys.ch/hardware-virtualization-solutions/virtual-sparcstation/
Otherwise, I would also recommend buying used hardware.
