Why can't I change my RTL destination directory using the dspba.set_param command as shown in the DSP Builder for Intel® FPGAs Handbook?

Description

Due to an update in the Quartus® II software v15.0 release, the above command is no longer functional, even though it still shows in the handbook.

The handbook describes using "dspba.set_param(control{1},\'destination\',dest_dir)" to change the RTL destination directory.

Resolution

To change your RTL destination directory in the Quartus® II software v15.0 and later, use the following command:

dspba.SetRTLDestDir(model,dest_dir)

For example, if you are using the demo_fft.mdl example that comes with the DSP Builder for Intel® FPGAs (Advanced Blockset), use the following command:

dspba.SetRTLDestDir(\'demo_fft\',\'MyRTL\')
