XC3S datasheet - Spartan-3 Field Programmable Gate Array

If you have an official Xilinx Platform Cable around, it would be interesting to try it on your board. Do not post the same question on multiple forums. Revolutionary nanometer process technology Very low cost, high-performance logic solution for high-volume, consumer-oriented applications.

Here I must beg to differ. Every test provides additional information, whether the test fails or succeeds. Each functional element has an associated switch matrix that permits multiple connections to the routing. Apologies for being vague. It's also possible that Impact works around the problem in its newer versions.

Then if the both flops gets multiple triggers on the clock falling edge, but all those. Do not post a new topic or question on someone else's thread, start a new thread! Each individual character has a separate anode control input.

Not that it matters for in- house prototipes Regards. Search the forums and search the web for similar topics. This complete version is provided for easy downloading and searching of the complete document. The switches are located along the lower edge of the board, toward the right edge. Multiplier blocks accept two bit binary numbers as inputs and calculate the product.

Wasn't in their catalog last time I looked. Let's go through the possibilities. My jtag has recognized my xilinx. This is completely plausible.

All forum topics Previous Topic Next Topic. Make sure you use a scope with sufficient bandwidth and sampling rate to see the ringing if it is there. There are no negative-going pulses.

In any case the symptoms here are different. Read the manual or user guide. Do you see the same problem on all copies of your board? If I write a good post, then I have been good for nothing.

These are quite susceptible to noise on the clock. Consequently, our distributors aren't stocking them. Please upgrade to a Xilinx. Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.

How did we get to be so skilled in our debugging techniques? It would take repetetive sampling to see the full picture on this scope.


Note that the input to the clock buffer could have noise added to it that is not evident on the scope trace e. Toggle navigation Digchip. Until I see something to disprove that I would definitely bet beer on it. What is the problem please? If i put the xilinx alone, my jtag doesn't reconize the xilinx.

Hi Tim, I've looked for that after Teraspeed referenced it in an article and, like you, not found it yet. However it wouldn't hurt to implement these changes. Provide useful details with webpage, datasheet links, please. Create free account Forgot password? Note that the input to the clock buffer could have noise added to it that is not.

In any case as you already pointed out, metro bruselas plano pdf this is all speculation. It's about time they tried again! It should not have pulses unless it gets double-clocked.

Section Supplier Datasheet. Sadly, I can't remember the link. It might be time to bite the bullet and invest in a toaster oven! My gut feeling is that this is.

The true answer will eventually surface, laying any and all speculations to rest. In fact if the bypass mode is short enough one flip-flop? Introduction to Microcontrollers Mike Silva. Do you have more than one board to try?

On the other hand, internally generated data would presumably. Sure the internal logic will work ok, but that's what simulators are good at. If it's second, then the original symptoms are exactly what I'd expect to see. All specifications are subject to change without notice.
