HI,
I get following screen when I run step 4.3 (Build FPGA Bitstream) in HDL workflow advisor.
A screenshot is attached for reference.
It says build has started externelly but not happens after that.
Note :
vivado can be started from MATLAB window by !vivado.
NO bitstream is generated.
Kindly guide

Hi Rizwan,
The bitstream generation involves invoking an external shell for the third-party synthesis tool (in your case, Xilinx Vivado) to execute a TCL script. If the bistream is not generated and no external shell pops up for the same, you can try the below mentioned troubleshooting steps to resolve the issue:
  1. Make sure that that there is no antivirus that is blocking MATLAB from opening the external shell.
  2. Make sure that you have 'xterm' installed on your Linux device.
You can now try running the workflow again to check if the external shell pops up and the bitstream is generated.
Hope this helps!
