Description
Due to a problem in the Intel® Quartus® Prime Pro Edition Software v20.4, you will see this error when integrating the HDMI Intel® FPGA IP 2.0 Tx and the HDMI Intel® FPGA IP 2.1 RX into a design. This is because the module bitec_hdmi_aux_bch has the same module name between the HDMI Intel® FPGA IP 2.0 and the HDMI Intel® FPGA IP 2.1, but the parameters are different.
Resolution
This problem is fixed starting with the Intel® Quartus® Prime Pro Edition Software v21.3.
