1. ### Xilinx "RLOC" constraint

yep, I did, but i didn't help much (that's why I asked that question)
2. ### What is the IOB buffer used for? What is the global line in FPGA?

Why use IOB buffers in Xilinx FPGA? How does global line differs from ordinary line inside FPGA? -THX
3. ### Xilinx "RLOC" constraint

Hi, I've got a problem. There is a 3-bit counter (LOSS_CNT) in my design. What I want after place-and-route procedure is that all FFs of this counter are placed next to each other (not spread out across chip). How can I implement this? Of cource I can use LOC, but I do not want to assign it...
4. ### Extended Hamming Codes

what are the advantages of (8,4) over (7,4) if it still can correct no more than 1 error (as (7,4))? t=[dmin-1/2] [(4-1)/2] = [(3-1)/2]. if I use (7,4) code I can identify the position of 1 error using the value of syndrome. is it the same with (8,4)? -thx in advance
5. ### Extended Hamming Codes

Hello! People, I need your help!!!!!! For example, I have a parity-check matrix for (7,4). Let it be: % Parity-Check MAtrix H = [ 1 0 1 1 1 0 0; 1 1 1 0 0 1 0; 0 1 1 1 0 0 1 ]; % Generator MAtrix G = [ 1 0 0 0 1 1 0; 0 1 0 0 0 1 1; 0 0 1 0 1 1 1; 0 0...

11. ### analog design books - request for resources

Re: analog design books Thanks for the replies. Can anyone give his personal opinion about the next books? "Electronics by Allan Hambley" versus "Microelectronic Circuits by Sedra Smith" which one is better ? According to my survey I found that most designers recommend the next books: 1)...
