My design contains multiple clock islands which are running at different clock periods.
I am experiencing some problems when viewing signals in the Waveform Viewer, it appears that the Clock signals are not being displayed correctly in certain scenarios.
1) If I monitor signal only from one clock domain within a multiple clock system, the clock signal name shown in the Waveform Viewer is not correct. The frequency of the clock displayed is correct but the name of the clock is not correct, hence it will traverse to the wrong clock domain when selected.
2) If you monitor output signals from the clock islands at the top level, the clock signal names and the frequency is not displayed correctly.
This is a known issue in Vivado System Generator 2014.1 and will be resolved in 2014.2.
The data signals are correct, the issues are with the display of the clock signals for the multiple clock domains.
