15 years ago --- Quote Start --- I don't quite understand you. If you mean you are receiving 8 independant serial DDR channels each with its clock I don't see why you need dynamic delay if it is board issue. If the sensor data is so variable from source then I will assume each data has its own clock. Your own logic of AND OR is a pitfall I believe. --- Quote End --- Hi, sadly, I have just one clock and the 8 LVDS channels differ in phase to one another. The delay between the channels is due to the sensor - no board delay and it seems to change over different operating setting (SPI settings inside the sensor) - I have done successfull trainings with one setting while another fails ... The AND OR thing _is_ a pitfall since I have thought about it once more and Input AND (not(DelayReg(0) or DelayReg(1) or DelayReg(2) or DelayReg(3)) would be an equivalent simplification when you "ignored" the timing. => The fitter wouldn't leave anything of it.
