    Are there any Thin-X clients for Linux?

    I also suggest that using VNC is a good choice which is better than other solutoins. It will transmit the whole screen and establish a standalone xhost in the remote machine. You don't need to worry about the carsh of remote xhost happening in the remote machine. I have forgot XDMCP after using...

    cadence ic 5141 on redhat 9 or enterprise 4 AS

    how to install cadence ic5141 I have run ic5141 at centos v4.x, this version is equal to the enterprise version of RedHat, and there is no problem at all. As far as I know, there is no need to set LD_LIBRARY_PATH since it will be set automatically when you running the script of launching icfb...

    pic18f4550, Full speed but usb 1.1 compatible?

    what is the speed of usb2.0 and 1.1 As far as I know, there are some electrical difference between USB 1.1 and 2.0. As you can see, USB 2.0 also support Full speed and it's backward compitable with spec 1.1. Many companies usually say that they meet spec 2.0 even only support full speed...;)

    How does an incremental ATPG work?

    incremental ATPG I have no tutorial in hand. As far as I know, The incremental ATPG just combine several test patterns with different toggle rate in order to get a final test pattern with best toggle rate....You can also think that the incremental ATPG is just the union set of several...

    Why many EDA vendors use TCL/TK to develop their EDA tools?

    Why use TCL/TK? I am the user of Perl....Is there any converter for perl to tcl ? or bidirection converter is even better...There are several eda tools made by Perl, I just don't know why they don't support perl....It's will be better if perl interpreter is insided....;)

    Looking for clock recovery circuit for USB 2.0

    about clock recovery For my opinion, just search about the reference of DLL(Delay Looked Loop) and apply it not only clock recovery but also data extraction. Hope this is helpful for you...;)

    When Tapeout review, need check what?

    I think there is also a need of pass in formal verification of any modification or ECO in the netlist....hope this is heplful...;)

    Information about SystemVerilog

    about verification I am also the supporter of system Verilog, though I am not familier enough...:) I am also the user of verilog now...;) I think learning system verilog should be more easiler than system C for me..:)

    Can a USB host be implemented using an 8 bit uC?

    chicken_feet, Has you studied the host spec for OHCI or UHCI ? If not, I suggest that you should study it first in order to know the tasks that host should do. After that, I think you may know the real problem for 8 bit mcu to implement functions of host mode.
