Quartus Pro v21.1. Synthesis error of two independent instance of FFT

[vdpavel]

Hi,

Yesterday I got temporary license for Quartus Prime Pro. And stucked right at the beginning of using Pro version. In the past I always used Standard version of quartus. Very simple test is not compiling by Pro version. Test project attached. Project contains just top file, and 2 qsys files of "FFT Intel FPGA IP". If use only one FFT - everything is ok. But if add second one - fail. Compilation fails during "Synthesis". Standard version of quartus compiles as expected without problems. The same situation with NCO.

I tried to investigate errors and found out, that quaruts pro generates tmp-clearbox directory with *.tdf files. I guess that some of this files are used by fft. Inside some of this files full path to  hex files:

INIT_FILE="fft_a/altera_fft_ii_191/synth/fft_a_altera_fft_ii_191_glumlpq_3n256cos.hex",

some files contains just name of hex wihtout path:

INIT_FILE="fft_b_altera_fft_ii_191_tdfvdzi_2n512sin.hex".

Screenshot of quartus report in attached jpg file. Is it a bug of quartus or I do something wrong?
