Hi linas,

My compilation of the example using Quartus 9.0 was successful unless only .sof was created due to the Web Edition I guess.

But when I tried to do the same using Quartus 12.1 Build 177 (Web Edition too) there was such a result:

Strings from the bash window:

Info: save_system test_sys_sopc

Error: set_parameter cpu setting_shadowRegisterSetsPresent false: null

set_parameter cpu setting_numShadowRegisterSets 1: null

set_parameter cpu setting_eicPresent false: null

set_parameter cpu setting_autoAssignNumShadowRegisterSets true: null

SOPC Builder was created successfully…

SOPC Builder was NOT generated successfully…

Error in build_and_generate_sopc_system…

Unfortunately I don't know why in the previous version of Quartus this error was not found but in this version was.

I don't know the destination of the parameter 'cpu setting_shadowRegisterSetsPresent'.

After I tried to comment it out the next error was displayed

Error: set_parameter cpu setting_numShadowRegisterSets 1: null ... and so on

I know that the last Quartus versions use the Qsys instead of SOPC Builder. These both systems are similar more over in the Qsys windows one can see many mentions of the SOPC Builder. So hardly it is the reason of the error found.

You wrote your experience in using Quartus 12 was successful.

Could not you advise why my experiment was not.
