Dear all：I was use ip complier for pcie to realize pcie interface,completer only,single dw completer,endpoints mode,without CRA, generated by qsys. Now, i want to use legacy interrupt, base on the handbook: 1、after power up, the ip core starts in intx mode 2、in legacy mode,the app_int_sts input port controls interrupt generation.
3、in my qsys ，pcie interrupt enable register bit was assigned to 0x0000ffff
But i can't find the app_int_sts in qsys,and in this file"pcie_hard_ip_0" app_int_sts was assigned to 0. So,how can i use legacy interrupt with completer only,single DW mode ? Which signal can be export to top level to assert interrupt? please give me some suggestion ,thanks very much! software version :13.1 youming
