Hi,
I am trying to run HDL work flow adviser for the standard LED blink example from MATLAB. I am new to this style of programming FPGA, can someone advice me what to do or where I can find a solution. This is the following error:
Failed

This error is coming directly from Xilinx Vivado, and seems pretty clear. For whatever reason, Xilinx wants your project root directory to have fewer than 80 characters in its name. The name you are using is 'C:/FPGA_Programming/hdl_prj/ipcore/hdlcoder_led_blinking_led_counter_ipcore_v1_0/prj_ip', which is 87 characters long:
>> length('C:/FPGA_Programming/hdl_prj/ipcore/hdlcoder_led_blinking_led_counter_ipcore_v1_0/prj_ip')
ans =
87
The solution is obvious; shorten this path however you can, or use the subst command as suggested.
