no such variable (read trace on "env(DSPBA_ROOTDIR)") - no such variable (read trace on "env(DSPBA_ROOTDIR)") Description Due to a problem in the Intel® Quartus® Prime Pro Edition software version 20.3, you may see the following IPs fail to launch correctly with this error message. Any Unified FFT Intel FPGA IP FIR II Intel FPGA IP CORDIC Intel FPGA IP Fixed Point Functions Intel FPGA IP Floating Point Functions Intel FPGA IP Floating Point Custom Accumulator Intel FPGA IP This problem occurs because the environment variable DSPBA_ROOTDIR is not set at runtime. Resolution To work around this problem, set the environment variable DSPBA_ROOTDIR manually If you have already set QUARTUS_ROOTDIR in your environment, then you can set DSPBA_ROOTDIR relative to QUARTUS_ROOTDIR. DSPBA_ROOTDIR is the full path to the location of the dspba/ folder under QUARTUS_ROOTDIR. For Linux, in a bash shell: export DSPBA_ROOTDIR=$QUARTUS_ROOTDIR/dspba For Windows: 1) Go to Control Panel->System->Advanced system settings->Environment Variables 2) Set DSPBA_ROOTDIR to %QUARTUS_ROOTDIR%\dspba If you have not already set QUARTUS_ROOTDIR in your environment then DSPBA_ROOTDIR can be directly set to <quartus-install-path>/quartus/dspba where <quartus-install-path> is the location you specified when you installed the Intel® Quartus® Prime Pro Edition software. For Linux, in a bash shell: export DSPBA_ROOTDIR=/quartus/dspba For Windows: 1) Go to Control Panel->System->Advanced system settings->Environment Variables 2) Set DSPBA_ROOTDIR to \quartus\dspba This problem is fixed starting with the Intel® Quartus® Prime Pro Edition software version 20.4.
