Potential Bugs in R2014b HDL Coder ('hdlcoder_slsysgen')

I am using R2014b and Vivado 2014.3. I try to run the 'hdlcoder_slsysgen' demo, which contains a simulink block and a block with sysgen. I am using HDL Coder Workflow Advisor to do the code generation (and setup with Vivado synthesis tools). However, during the code generation phase, the HDL Coder calls a script SgSwitchLibrary.pm but returns an error "cannot find the script file". This script file was no longer supported by Xilinx Vivado 2014.3. This must be a bug. Please help.

The integration between HDL Coder and Vivado System Generator is not supported by R2014b. The error message needs some improvement.

I also find the R2014b + Vivado 2014.3/.4 combination very interesting, but Yongfeng's comment is making me doubt. FYI, I opened a thread to clarify these compatibility aspects here.

Regards!

Please note that ISE System Generator is different from Vivado System Generator. The HDL Coder feature of "Using Xilinx System Generator for DSP with HDL Coder" (<http://www.mathworks.com/help/hdlcoder/ug/using-xilinx-system-generator-for-dsp-with-hdl-coder.html> and http://www.mathworks.com/help/hdlcoder/ug/code-generation-with-xilinx-system-generator-subsystems.html ), in which HDL Coder calls System Generator to generate code for Xilinx Blocks, supports only ISE System Generator but not Vivado System Generator in R2014b, although Vivado System Generator by itself may work with Simulink in R2014b. Because of this limitation, the 'hdlcoder_slsysgen' example still works with ISE System Generator, but gives error with Vivado System Generator.
