XSG - Vivado 2020.1 / Matlab 2020a Update6 - Error evaluating 'OpenFcn' callback of Xilinx Register Block block (mask)

[opal-rt_fpga_grp]

Hi,

After having updated Matlab 2020a to Update 6, when a I double-click on basic elements such register (or constant), I received a message error without being capable to set a value.

How to resolve this?

MATLAB Version: 9.8.0.1538580 (R2020a) Update 6
MATLAB License Number: 528812
Operating System: Microsoft Windows 10 Pro Version 10.0 (Build 18362)

>> xilinx.environment.getversion('sysgen')

ans =

'2020.1'

Best regards,

Even if with the Xilinx token / Xilinx System Generator block! Not able to open the GUI interface! Quite a worrying situation, could you help me on this?

Are you getting any error as shown below after adding XSG block into canvas?

If so, can you please make sure you are invoking System generator tool and not Matlab/Simulink directly. I know its a basic thing and user in general don't do such things. But, just to rule out that is not the case from your end.

Absolutely not! The XSG environment is set correctly:

 

All you have to do to reproduce is to use Vivad0 2020.1/Matlab 2020a, create a Simulink blanl model, add the XSG block (or simple register block) and double-click on it.

Hi @opal-rt_fpga_grp ,

These steps have helped resolved the issue 

• Run MATLAB configurator for Sysgen in administrator mode
• Clear the MATLAB configuration
• Re-launch the MATLAB configurator tool again in admin mode
• Configure the MATLAB version R2020a
• Launch Sysgen
