Hi,
When I tried to activate DDS modules in the M2k HDL source disabled by default, I found that the ad_dds has been successfully instantiated and connected with the tx path of the axi_ad9963.
However, a stragne behavior in the output signal has been observed; the output frequency changes when I vary the initial phase.
I found that in the line 219 of axi_ad9963_tx_channel.v,
.tone_1_freq_word (dac_dds_init_2_s),
the initial phase of tone_2 has been wrongly passed to the frequency of tone_1. The correct code would be,
.tone_1_freq_word (dac_dds_incr_1_s),
After this modefication, the DDSs in M2k work correctly as I expected.
Please check it. A similar possible bug has also been found in axi_ad9122.
