Q: Should TCK be pulled up or down on Altera devices?

Answer:

Since 2000, Altera devices have been designed for a pull down resistor on TCK for both 3.3 and 5V devices. Please note that most non-Altera devices tend to expect a pull-up resistor on TCK or they even have built-in pull-up resistor on TCK/TMS/TDI.
