Hi ,
I create a instance of DCM as follows :
DCM i_DCM (...
...
...
) /* synthesis xc_props ="DLL_FREQUENCY_MODE =
LOW,DUTY_CYCLE_CORRECTION = TRUE, <more parameters > */; //note this
directive is on a single line without line-breaks
But I see that in the post-synthesis .vm file there is no defparams
added for these attributes.
Please suggest,
Thanks,
Sudhir

Stats I've seen (sorry, no citation) gave the mortality rate for the 1918
flu outbreak as 10%
of infections, for the current strain 50%+.

Article: 95338Dear all I'm starting with LVDS. My task is sending 8-bits signal to LVDS Transmitter port on my board. I declared a 8 bits vector, assigned pins, and changed values in 8-bits signal, but nothing happended in my oscilloscope. Assume that pins-out are right assigned, all wires and DAC are working perfectly. Can anyone advise me, how to make it works. Many thanks FrankArticle: 95339

There are devices that have a camera mounted vertically with a monitor overtop, used for people who have poor vision, but they cost several thousands of dollars (small market) if you can't get a subsidy on them. I wonder if you could do the same thing with a decent camera and an inexpensive monitor. It's got to be better to just move the book around under the camera than waiting while the scanner whines and grinds its way through each frame. There are also dedicated reading machines such as the Xerox "Reading Edge" which will read books aloud with fair success (you have to get used to the text-to-speech 'accent' they have).

Frank Remember to check the scale on your oscilloscpe. The LVDS signal is very small and easy to miss if setup for something like TTL levels. I've done that before myself. If you are using Xilinx you can check if LVDS is implemented from the pin file I think or do it my favorite way in by looking at the design in FPGA editor.
