    Anyone can help to identify this digital comm textbook?

    Yes! I think it is the book..

    Anyone can help to identify this digital comm textbook?

    I happen to see one chapter of this book, but I think I want to get the entire book instead. I only scanned one page shown below, you can see the chapter, section and more info.. Thank you in advance! **broken link removed** :?:

    Sample scripts for SOC Encounter, where can I find?

    running tcl script for soc encounter In design compiler, we could write a single script, either in tcl or sdc to compile a design until netlist. My new tool is SOC Encounter, I was only aware in SOC Enc I must use the GUI to import RTL codes. My side uses Unix and the GUI has mistakes...

    how to write 64 Bytes of data?

    If you use Coregen, you can set some initial data when generating the memories.

    are there any visual C++ to VHDL converter out there?

    vhdl visuell SystemC, which has been arround but failed to gain popularity. I bet its application is limited. Basically RTL engineers translates C++ codes into Verilog/VHDL.

    how to desin "start/pause button" in verilog

    pause in verilog You need some debouncing circuits, since everytime you press the button, the circuit receives multiple pulses instead of one transition. Check out this project! **broken link removed**

    test vector generating s/w..

    Depending on your specification, some standards give you test codes. other standard you have to write your own C/Matlab code. C++ fixed point -> HDL-> FPGA is a standard flow.

    Can i fix my spartan 3a starter kit after i plug to it 12V?

    the FPGA is dead i guess. few years back when probing signal, my connector touched one pin on a Spartan-2, and spark! It's gone. I guess FPGAs are very volatile.

    Do probability and statistic have application in electrical

    Yes, statitics and probablity are very important in communications, and that's an area which I am dificient in.

    Documents which explain poles and zeros in control systems/analog circuits

    modern control systems dorf rapidshare Concept is very simple. When you see a pole, the output from the transfer function give you a infinite value.. WHen you see a zero, the output is 0.

    What software do you use to draw logic gates and transisters

    draw logic gates I have been looking for freewares to draw documentations, but never found it. And a software to draw timing diagram, responses, analog waveforms, wtc?

    Who uses SynaptiCAD products

    Yes, drawing timing diagram is very nice. I hope the software is free instead of limited license!

    Ideas for adding functionality to ASIC project

    asic project idea Yes you can. ASIC is a very broad concept. It's full name is application specific integrated circuit. As I said, FPGA is cheaper and whenever you tough ASIC, you committed hundreds of thousands of US$ already and more than one years of time. FPGA to do the same job costs...

    how to implement Look-Up table in verilog

    Modify this code sliplet and you have a look up table. function [3:0] bit_sel; input [63:0] hist; input [3:0] idx; reg [3:0] state; begin case (idx) 4'hF: bit_sel = hist[ 3:0 ]; 4'hE: bit_sel = hist[ 7:4 ]; 4'hD: bit_sel = hist[11:8 ]; 4'hC: bit_sel = hist[15:12]; 4'hB: bit_sel =...
