Hello,
I am running the gain block testbench from the getting started page. The
first four tests succeed, however the fifth one keeps running without any
conclusive result. Attached is the test result. The other thing I have
noticed is that the test result for the first four is less verbose than the
one given on the getting started page. Some display statements are missing.
Is there a way to make the output more verbose?
I am using UHD 4.0.0.rfnoc-devel-409-gec9138eb and Vivado 2015.
Thank you,
Pratik
