is there any opensource alternatives to platformstudio and microblaze development?

Do you want open source for microblaze development specifically? Or opensource for any open source 32-bit embedded micro?

Lattice Mico32 development might fit the bill for the second...

im looking for a complete set of tools and ip cores with some good documentation.

You might want to check out the LEON processors.

You could also use some free cores from opencores.org. Lots of IP blocks there built around the Wishbone bus (including a few processors). But going this route, you don't have a nice integrated GUI that EDK provides.

There is a WISHBONE Builder project at opencores.org:

I have not used it, so I can not compare it to EDK.

There is also a collection of processors and other cores that use the WISHBONE interface:

Another site you might find interesting is the gEDA site at:

This is a collection of GPL EDA tools.
