output ports not found after synthesis

Hello everyone,


I'm working with the reference design FMCMOTCON2. I want to integrate my own IP generated by System Generator into the reference design, in oder that the corresponding LED will be switched on, when I turn on a switch.


The steps below describes what I did:

1. I use the input signal "gpio_i[63:0]" in the block design as the input signal to my IP.

2. The IP extracts a 8-bit range of bits out of the 64-bit input signal, which are corresponding to eight user switches on the Zedboard.

3. The bit slice is connected to a "Gatway Out" output port, which represents 8 LEDs.

4. With the IP integrated, I connect gpio_i[63:0] the the input port of my IP and make external for the LED output port.

5. In the file "system_constr.xdc", the following sentences are added:

    set_property -dict {PACKAGE_PIN  T22   IOSTANDARD LVCMOS33} [get_ports ld[0]]      ; ## LD0

    set_property -dict {PACKAGE_PIN  T21   IOSTANDARD LVCMOS33} [get_ports ld[1]]      ; ## LD1

    set_property -dict {PACKAGE_PIN  U22   IOSTANDARD LVCMOS33} [get_ports ld[2]]      ; ## LD2

    set_property -dict {PACKAGE_PIN  U21   IOSTANDARD LVCMOS33} [get_ports ld[3]]      ; ## LD3

    set_property -dict {PACKAGE_PIN  V22   IOSTANDARD LVCMOS33} [get_ports ld[4]]      ; ## LD4

    set_property -dict {PACKAGE_PIN  W22   IOSTANDARD LVCMOS33} [get_ports ld[5]]      ; ## LD5

    set_property -dict {PACKAGE_PIN  U19   IOSTANDARD LVCMOS33} [get_ports ld[6]]      ; ## LD6

    set_property -dict {PACKAGE_PIN  U14   IOSTANDARD LVCMOS33} [get_ports ld[7]]      ; ## LD7


But after the syntehsis completed, I couldn't find these eight LED output ports on the I/O Ports window. The ports listed here are only the ports that originally exist in the reference desgin.


How to slove this problem?
