If you choose not to install the Stratix® II device family during the Quartus® II development software install and try to create a custom component in SOPC Builder, during the process of analyzing the HDL file you may get the following:
"Error: Family Name "Stratix II" is illegal"
For Quartus II PC, you will need to go back and install the Stratix II device family to resolve the issue.
For Quartus II Linux, you can modify the "quartus_map" executable file by adding the following lines before the final "eval exec...". (Note: You may replace CYCLONEII in the following example with any device family you have installed.)
setenv GOOD 0
echo | grep not_a_project || setenv GOOD 1
if ( == 0 ) then
set cmd_line=( \--family=CYCLONEII\)
endif
This issue will be fixed in a future release of the Quartus II development software.
