How to package a custom IP containing IP as submodule

Hi,

I have created simple design where I instantiate LPM_sub_add IP as submodule. I would like to package the whole top level so that I can reuse IP. Below are the steps used:

  1. Create a new component in Platform designer.
  2. I added the .qip file of the IP along with top VHDL file in the synthesis files.

While generating the complete IP I am seeing bunch of errors:

Error: Component add1 can't instantiate a custom component with the same name as itself

Error: add1.add1_0.add1_0: Component add1 1.0 not found or could not be instantiated

Error: add1.clk_0.clk/add1_0.clock: Missing connection end (try "Remove Dangling Connections")

Error: add1.add1_0: add1_0.clk must be connected to a clock output

Error: add1.add1_0.add1_0: Component add1 1.0 not found or could not be instantiated

Error: add1.clk_0.clk/add1_0.clock: Missing connection end (try "Remove Dangling Connections")

Error: add1.add1_0: add1_0.clk must be connected to a clock output

Error: add1_0: missing_module does not support generation.

Error: qsys-generate failed with exit code 1: 4 Errors, 3 Warnings

I guess somehow I have to stitch the netlsit but not sure though. I am not sure if I am missing something basic here. Can someone please guide me with the exact steps to package a custom IP which has submodule IPs?

Thanks,

    Thanks for your reply @KennyT_Intel​ How can I use this Tcl command in the platform designer? Does the platform designer have Tcl console?

    @KennyT_Intel​ let me elaborate the issue. I have attached a simple test case where I have instantiated LPM_sub_add IP. I want to package the entire led_comp module. It means I have to package the entire system which includes the IP.

    According to your reply, I think I should add the Tcl command in hw.tcl. However, I am confused, how can I pass information regarding port map. Can you please provide elaborate steps on how to proceed for the same. My actual implementation is on a big project. If you can guide me for this simple testcase, then that will provide me reference for the main design. Thanks for your help in advance.

    Do you have service portal where I can raise a request?

    @KennyT_Intel​ thanks a lot for your design file. But unfortunately I am unable to open the file as I dont have the device installed. I am using quartus prime 17.1 with device Cyclone V 5CGXFC7C7F23C8. Is it possible to share the design file for the mentioned device and version of the tool?

    where can I find the properties of the IP to be used as Tcl command? Is there a file generated that can guide me?

    I will resend you the design.qar.

    For the properties of the IP, you will have to look into the specific IP user guide.

      Hi @KennyT_Intel​

      I tried Looking into the https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug_fifo.pdf for FIFO. I could not find the exact Parameters you are mentioning. It's neither intutive nor straightforward. Can you please share if there is some file I can use as reference to write These Parameters.

      set_instance_parameter_value mfifo GUI_AlmostEmpty "false"

      set_instance_parameter_value mfifo GUI_AlmostEmptyThr "1"

      set_instance_parameter_value mfifo GUI_AlmostFull "false"

      set_instance_parameter_value mfifo GUI_AlmostFullThr "1"

    I look into the design.qar again, it will be better that I dont modify it as a lot of properties are tied to Arria 10. What I suggest is you download and install this device in

    http://fpgasoftware.intel.com/18.1/?edition=standard&platform=linux

    Choose the version that you want and click individual files. From there you can choose the specific device to be download qdz files.

    After that, in Quartus, just click tools -> install device to install the arria 10 device.
