yes ,"run" means compile from SOPC system to the whole quartusII system.

this problem is still puzzling me ...

now ,I think of another question,that is :I want to set memory initialization file (.hex) of on_chip_memory ,and then use a SGDMA to get data from the memory,I add the data in .hex manually(how to add data into the .hex file automatically??) in quartusII,

but when I open the file in the form of .txt, and find that the data in the .txt is very different??

is the .hex data not only contain the useful data but also the head data or somthing?how to add data into the .hex file automatically??

if I want to add data of a picture in the on_chip_memory,how to translate the picture into .hex file then can be added in quartusII ??
