Hi!,

Here is the reply I got from Altera. I could solve this issue following the steps listed down.

For error message "isa_europa.pm: calc_max_control_reg_sz(): No register size available for register cpuid", it is a running environment issue. If you have multi-version installation of Quartus II, when using v9.0, please make sure the following environment variables are set as follows (for example):

QUARTUS_ROOTDIR = C:\ALTERA\90\quartus

SOPC_KIT_NIOS2 = C:\ALTERA\90\nios2eds

Please also delete environment variable SOPC_BUILDER_PATH (but you need to save the values for restoring when using versions other than v9.0).

When using Quartus II/IP/Nios II EDS before v9.0 (such as v8.1), please recover the environment variable SOPC_BUILDER_PATH and set the value of the environment variables as follows (for example):

QUARTUS_ROOTDIR = C:\ALTERA\81\quartus

SOPC_KIT_NIOS2 = C:\ALTERA\81\nios2eds

Then remove the following folders and restart Quartus II to try it again.

c:\documents and settings\<user name>\.altera.quartus

c:\documents and settings\<user name>\ipToolbench

c:\documents and settings\<user name>\.sopc_builder.

Best Regards
