Help: ICE_FLAGS_CLKDLY=N

Delays input clock by N nanoseconds for clock/data deskew


Delays the input clock by N nanoseconds (1.2ns taps) to adjust the clock 
edge to the center of eye pattern on noisy or non-standard input signals.
This is usually used with CLKI to clock data on the rising edge delayed 
by 1/2 wavelength + N nanoseconds.  Signals that show skew between the clock 
edge and data edges by the time they reach the input modules can use 
this to correct the situation on PIC4/MBT4 cards.  Note, the 1/2 wavelength
is applied internally when the rising edge is used.  The CLKDLY=N value is
added to this.

The PIC3/MBT3 cards will clock on the rising or falling edges only 
but with data/clock skew < 1 ns.  These cards should not need any 
correction up to their maximum sample rate of 65MHz.
