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.

I never used them myself though. It's free if your project is open- source, if it's closed-source you must pay for the license.

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.
