Honored ContributorI used Xilinx a long time ago. In Xilinx World the Micro/picoblaze at that time communicated to the other components using buses: OPB and PLB for example.
The name for EDK in Altera World is SOPC Builder (or Qsys if you want to try the newest). Take a look to Avalon Bus Specifications: you may find some details. Someone on this forum also posted some examples of custom components using avalon bus. Hope this helps you. I have some difficulties to understand why you want to make the *blaze/Nios II communicate with the FPGA: it is built with FPGA resources. It may be a language problem since English is not my mother tongue.
