Hi,


As I understand it, you are observing some license problem when trying to generate netlist with DSP Builder. To ensure we are on the same page, just to check with you on the following:


1. What is the device that you are using?


2. Are you using Pro or Standard Edition?


3. What is the Matlab version that you are using?


4. Generally the Quartus license file is a .dat file. Just to check with you if you are setting the LM_LICENSE_FILE environment variable to the .dat file or the directory? It is recommended to point to the .dat file directly.


5. During your DSP Builder installation, you would need to install the compatible Matlab version first then only installl the DSP Builder. Just to double check with you.


Please let me know if there is any concern. Thank you.
