--- Quote Start --- How do you do that when one of the clocks is the one I'd have to use to clock signaltap? Besides, I can see it on a scope, and the two signals come up different every time. --- Quote End --- Kindly Check the below image attached. In image we have one signal that is having frequency of 1kHz(red color), which is generated by 10Khz. And ticks at top of signal tap are generated by clock frequency/sampling clock(10Khz). which we gave in signal taps clock field. And in image we can see the change in output clock with respect to the input clock(Rising-edge). --- Quote Start --- Besides, I can see it on a scope, and the two signals come up different every time. --- Quote End --- Yes, we can use if oscilloscope is calibrated and probes are working fine. Even if, It is calibrated we will have small phase shift which is not noticeable.In your case we dont know it is because of oscilloscope,probe or coding. So only i suggested for signal tap. During debug it will be helpful. Best Regards, Anand Raj Shankar (This message was posted on behalf of Intel Corporation)
