请教，在用quartus编译nios核时出现了如下错误

gfcong

Error: Project too complex: hierarchy path is too long
Error: Entity "altsyncram_hbv" is instantiated by entity "altsyncram"
Error: Entity "altsyncram" is instantiated by entity "boot_ROM"
Error: Entity "boot_ROM" is instantiated by entity "nios"
Error: Entity "nios" is instantiated by entity "nios_cpu"
之后就是后俩句的循环，有一百多
还望高手指教

是不是LICENSE有问题
