unable to load valid reference design plugin

Hello,

I'm now using HDL coder to do implementation for my Zedboard. But when I usd the HDL workflow advisor, I got an error from phase 4.1. Create Project. The error message is: Faild Unable to load valid reference design plugin. I'm using MATLAB 2013b and Xilinx ISE Design Suite 14.4 Please help me to get rid of the error, thanks.

Hello, I have the same problem, "Step 4.1 Failed, unable to load valid reference design plugin," but I am using an AXI4-Lite interface (I am trying to run the hdlcoder_led_blinking example). I am using MATLAB 2013b and Xilinx ISE 14.7. Any help troubleshooting this problem would be appreciated. Thanks, Grant

Hi, Grant

It seems that in the previous version before R2014a, we should have at least 1 AXI4-Lite port to get rid of the error in the step 4.1. I had this problem just because of that. As described in your situation, I don't know why it doesn't work for you.

Hi Grant,

MATLAB 2013b only support Xilinx ISE 14.4, so you see this error message in 2013b when you use ISE 14.7. Please switch to ISE 14.4 to remove this error.

Starting from R2014a, you can use ISE 14.7.

Thanks, Wang

Hello, I also have problems adding the Zybo platform to the HDL coder workflow advisor in Matlab 2014b. I have vivado 2015.1. do you know if they are not compatible? Besides, do you know if I need to have Vivado HLS to create an IP core?

thanks

Hi Juan,

1. 2014b HDL Coder is compatible with Vivado 2013.4.
2. In 2015a HDL Coder, there is a shipping example about how to add Zybo platform to the HDL Workflow Advisor: Link to the example
3. You can create an IP core using "IP Core Generation" workflow in HDL Workflow Advisor.

Thanks, Wang

great thank you!!

Hi Roger, In HDL Workflow Advisor Step 1.2 "Set Target Interface", In the table "Target platform interface table", do you have one of your port assigned to "AXI4-Lite" interface?

There is a bug in R2013b MATLAB that at least one port must be assigned to "AXI4-Lite" interface in "Target platform interface table", or else Step 4.1 "Create Project" will fail on project creation. This bug is fixed in R2014a MATLAB.

Thanks, Wang

Hi, Yes, it is just as you said, thank you!
