Hello ,sorry bad English.
About https://code.google.com/p/fpgagen/ .

de1 of new version doesn't run gen_top.sof.
Does anyone succeed run gen_top.sof by de1 of new version.
First,I doubt boot sector of flash.
But,Both S29AL032D70TFI04 and s29gl032n90tfi04 is bottom boot.
So,It is that gen_top.sof isn't work,Speed of flash memory is cause(70ns -> 90ns).
I did browse the source.
Cause maybe is os_rom.vhd.
But,I can't understand fixed point.
What should I fix ?

-------------------------------------------------------------------------------
...
init_file => "../../../../Downloads/bin2mif-master/bin2mif-master/hello.mif",
intended_device_family => "Cyclone II",
...

-------------------------------------------------------------------------------
But I skip detail,"Hello sega World" was successful.
But ,Genesis_OS_ROM was not successful.

Please Does someone write os_rom,or teach fixed point.

Thanks
