Hi,


  • Do you have another FPGA to try with the same board? Does it give the same output?
  • Can you provide the configuration scopeshot?

hi，Aiman，

Surely，Actually I tried three chips from differrent shops with the same board. but get the same result.

(the same simple RTL test can work with EPM3032ATC44. unfortunately, its LEs are not enough.)

please find attched for QSF and whole output_files directory, it should include all logs and settings.

thanks!
