Due to a problem in the Intel® Quartus® Prime Pro Edition software versions 19.1, 18.2, 18.1.1 and 18.1, when using the HDMI protocol option for fPLL IP, users will see the following fitter error message:
Error(15653): The Fitter cannot find a legal configuration for the following atoms. Update any outdated transceiver PHY IP cores, correct any illegal pin assignments, and then recompile your design.
Error(15744): In atom 'u0|xcvr_fpll_s10_htile_0|fpll_inst'
Error(15744): The settings must match one or more of these conditions:
Error(15744): ( primary_use != TX ) OR ( side == LEFT ) OR ( f_min_pfd == 50000000 )
Error(15744): But the following assignments violate the above conditions:
Error(15744): side = SIDE_OFF
Error(15744): f_min_pfd = 25000000
Error(15744): primary_use = TX
The HDMI protocol option is not supported for the Intel® Quartus® Prime Pro Edition software versions 19.1, 18.2, 18.1.1 and 18.1.
This problem is fixed in Intel® Quartus® Prime Pro Edition software version 19.2. For Intel® Quartus® Prime Pro versions prior to 19.2, use Basic protocol mode.
