Error selecting target in R2020a and Vivado 2020

Dear Community,

I am trying to get familirized with HDL generation from Simulink.

I tried the "workflow advisor" button from upper left corner.

At first stage I tried to select a board, but I got an error, see picture attached.

error: Target platform "XUP Atlys Spartan-6 development board" requires one of the following synthesis tools: Xilinx ISE

I set the HDL tool path using:

hdlsetuptoolpath...
    ('ToolName','Xilinx Vivado','ToolPath','C:/Xilinx/Vivado/2020.1/bin')

I restarted Matlab

it did not helped..

Why is asking for a tool almost 10 years old??

What to do to get rid of the error??

Please help

Miquel

Hi Miquel,

For Spartan-6 FPGA device, Xilinx requires Xilinx ISE as synthesis tool. You cannot use Xilinx Vivado for Spartan-6 device.

For newer Vivado-based FPGA device like Zynq, Zynq Ultrascale+, Kintex-7, Virtex-7, please use the IP core generation workflow in HDL Workflow Advisor. You can refer to following example to get started:

Thanks,

Hi Wang,

I tried Virtex-6 board and I get same error.

No matter what board I select it gives same error!!!

I was hopping Matlab would help me speed up my work if I select the board I am using.

working from ground zero with IP core generation.. is something I would have avoided...

Thank you

Hi Miquel,

Virtex-6 is also the older device that is only supported by Xilinx ISE.

Vivado only support Virtex-7 and up. This is the limitation of Xilinx tools.

I highly recommend you use IP core generation workflow for the newer Vivado-based Xilinx devices.

If you want to use the older board (Spartan-6, Virtex-6), please use Xilinx ISE as synthesis tool.

Thanks,

Wang

Ok,

Apparenlty there are two methods to work with FPGA boards and Matlab: "FPGA in the loop (FIL)" and " Turnkey".

I finally found out that >>filWizard provides a list of boards. Most of them are enabled for FIL . So I will go wiht Digilent Arty A7 and FIL

Cheers
