Cortex-M0 DesignStart ready for Altera FPGAs

Hello together, I am little bit confused regarding to the Cortex-M0DS comparability to Altera FPGAs.

On one hand, according to the information out of the white paper An introduction to ARM Cortex-M0 Design Start it must be possible to run the Cortex-M0 DS on an Altera FPGA because the DesignStart DesignKit deliver a synthesizable Verilog Version of the processor.

On the other hand till now I only find Master Thesis or Step by Step Guides like (STEP BY STEP GUIDE TO IMPLEMENTING THE CORTEX-M0 USING A NEXYS2 FPGA BOARD) which uses development boards based on Xilinx FPGAs.

So my questions are:

• Is it possible to use the Cortex-M0 DesignStart with an Altera FPGA?
• Are there papers (Step by Step guides) which describes a usage of the DesignStart in combination with an Altera FPGA available?
• Why will ARM deliver a Prototype-board based on an ARM FPGA instead of an Xilinx FPGA?

Thank you and best regards

Stefan
