Both intel Quartus 19.1 version and DSP Builder 19.1 version are not compatible with each other - Both intel Quartus 19.1 version and DSP Builder 19.1 version are not compatible with each other It seems both intel Quartus 19.1 version and DSP Builder 19.1 version are not compatible with each other. Initially installed Quartus 19.1 from Intel downloads. Later I received DSP version 19.1 from the download page. Here is the error message. Quartus version is 19.1.0.240 and DSP is 19.1.0.670: Are there any alternative downloads available with identical version number? Or can you suggest a work around here?

Do you able to install the DSP builder successfully? Regards, Richard Tan Replies: Re: Both intel Quartus 19.1 version and DSP Builder 19.1 version are not compatible with each other Hi OP, You will need to install the DSP builder from the Quartus Prime Design Suite. Execute the "QuartusProSetup-19.1.0.240-windows.exe" instead of "DSPBuilderProSetup-19.1.0.240-windows.exe". Then select the DSP Builder Pro Edition in the Select Components window.
