Modifiying db files for epics, rebuilding and relaunching softioc

And here's the command history of what I used to edit and rebuild:

  224  cd /usr/local/epics/ioc/siocftdi/head/

  225  vi ftdiApp/Db/example1.db 

  226  make

When doing make the file gets copied over this folder

wenorum@ssd-sc-daq 217> ls -l ftdiApp/Db/example1.db db/example1.db 

-r--r--r-- 1 wenorum ssd 595 Oct  3 19:06 db/example1.db

 1026  ls ftdiApp/Db/

 1027  vi ftdiApp/Db/ftdiCommon.db

 1028  make

I've updated the 'run' script a little to try to ensure that multiple copies don't get started.

To summarize: 

ssh -Y ssd@ssd-sc-daq.dhcp.lbl.gov

......

cd /usr/local/epics/ioc/siocftdi/

sh -x run

Or, to attach to a running IOC to check its console messages or terminate it:

ssh -Y ssd@ssd-sc-daq.dhcp.lbl.gov

......

cd /usr/local/epics/ioc/siocftdi/

sh -x attach

Then type 'exit'

Also, all console messages are logged in

 /usr/local/epics/ioc/siocftdi/screenlog.0

Compiling xilinx Simulation libraries for modelsim

2.2 Simulation Library Compilation Wizard

This method is highly recommended because library compilation can be performed for more

than one device family and/or language.

1. Open the Simulation Library Compilation Wizard. This can be accessed from Start

Menu!Programs!Xilinx ISE Design Suite 13.x!ISE Design Tools!32-bit Tools.

Note: If you are using 64-bit version of ModelSim use the Simulation Library Compilation

Wizard from 64-bit Tools. ModelSim PE Student Version 10.x is only available in the

32-bit version.

2. The Select Simulator window opens up. Select the appropriate simulator (For Student

Edition select ModelSim PE), enter c:nmodeltech64 10.0cnwin64 for executable location,

compxlib.cfg for Compxlib Con guration File and compxlib.log for Compxlib Log File.

3. Next select the HDL used for simulation. If you are unsure select Both VHDL and Verilog.

However, this will increase the compilation time and the disk space required.

4. Then select all the device families that you will be working with. Again the more number

of devices, more the compilation time and the disk space required. Remember that you

can always run the compilation wizard at a later time for additional devices.

5. The next window is for Selecting libraries for Functional and Timing Simulation. Di erent

libraries are required for di erent types of simulation (behavioral, post-route, etc.). We

suggest that you select All Libraries as the default option. Interested users can refer to

Chapter 6 of the Xilinx Synthesis and Simulation Design Guide for additional information.

6. Finally the window for Output directory for compiled libraries is shown. We suggest to

leave the default values that Xilinx picks. Then select Launch Compile Process.

7. Be patient as the compilation can take a long time depending on the options that you

have chosen.

8. The compile process may have contain a lot of warnings but should be error-free. We

have not explored the reasons behind these warnings, but they do not appear to a ect

the simulation of any of our designs.

9. Once the process is completed, open c:nmodeltech64 10.0cnmodelsim.ini and verify if there

are libraries pointing to the output directory entered in step 6. This will happen only if

you have set the environment variables.

Library compilation is now complete. If you have not set the environment variables then

the wizard creates a modelsim.ini in the output directory entered in step 6. By default this

location is c:nXilinxn13.xnISE DSnISE. Open this le and verify that it contains the location of

the libraries that were just compiled. This le should be copied into every project you create.

Take a look at this PDF for more info.

putting custom template format into xilinx autogenerated files

If you have your own installation of the software you could hard code your changes into the Tcl scripts that control this.
For example, the company name could be entered for VHDL modules and VHDL TBs in the following files.

C:\xilinx\13.1\ISE_DS\ISE\data\projnav\scripts\dpm_sourceTasks.Tcl, line 713 – VHDL Module
C:\xilinx\13.1\ISE_DS\ISE\data\testbnch2.tcl – VHDL Testbench

I modified my file like this:  (however i had some issues later and it wasn't doing anything, just creating blank files, If you have a solution for this please let me know, if not try this under your own risk.)

Creating Components and libraries in Kicad

Refer to this tutorial, where it is well documented:

http://store.curiousinventor.com/guides/kicad/new_components/

compressing file from the command line and adding the date of creation to it

You need to use tar command as follows (syntax of tar command):
tar -zcvf LC52_`date +%b%d-%y`.tag.gz data/

Where,

• -z: Compress archive using gzip program
• -c: Create archive
• -v: Verbose i.e display progress while creating archive
• -f: Archive File name
• -x: Extract files

source: link for compresing and link for date on file 1, 2

Cygwin custom prompt

The next information is taken from (http://www.cyberciti.biz/tips/howto-linux-unix-bash-shell-setup-prompt.html) it is not mine. trying to fix my prompt in a new machine that doesn't show up anything, not even the folder where it is i found this:

Prompt is control via a special shell variable. You need to set PS1, PS2, PS3 and PS4 variable. If set, the value is executed as a command prior to issuing each primary prompt.

• PS1 - The value of this parameter is expanded (see PROMPTING below) and used as the primary prompt string. The default value is \s-\v\$ .
• PS2 - The value of this parameter is expanded as with PS1 and used as the secondary prompt string. The default is >
• PS3 - The value of this parameter is used as the prompt for the select command
• PS4 - The value of this parameter is expanded as with PS1 and the value is printed before each command bash displays during an execution trace. The first character of PS4 is replicated multiple times, as necessary, to indicate multiple levels of indirection. The default is +

How do I display current prompt setting?

Simply use echo command, enter:
$ echo $PS1Output:

\\u@\h \\W]\\$

How do I modify or change the prompt?

Modifying the prompt is easy task. Just assign a new value to PS1 and hit enter key:
My old prompt --> [vivek@105r2 ~]$
PS1="touch me : "
Output: My new prompt

touch me : 

So when executing interactively, bash displays the primary prompt PS1 when it is ready to read a command, and the secondary prompt PS2 when it needs more input to complete a command. Bash allows these prompt strings to be customized by inserting a number of backslash-escaped special characters that are decoded as follows:

• \a : an ASCII bell character (07)
• \d : the date in "Weekday Month Date" format (e.g., "Tue May 26")
• \D{format} : the format is passed to strftime(3) and the result is inserted into the prompt string; an empty format results in a locale-specific time representation. The braces are required
• \e : an ASCII escape character (033)
• \h : the hostname up to the first '.'
• \H : the hostname
• \j : the number of jobs currently managed by the shell
• \l : the basename of the shell’s terminal device name
• \n : newline
• \r : carriage return
• \s : the name of the shell, the basename of $0 (the portion following the final slash)
• \t : the current time in 24-hour HH:MM:SS format
• \T : the current time in 12-hour HH:MM:SS format
• \@ : the current time in 12-hour am/pm format
• \A : the current time in 24-hour HH:MM format
• \u : the username of the current user
• \v : the version of bash (e.g., 2.00)
• \V : the release of bash, version + patch level (e.g., 2.00.0)
• \w : the current working directory, with $HOME abbreviated with a tilde
• \W : the basename of the current working directory, with $HOME abbreviated with a tilde
• \! : the history number of this command
• \# : the command number of this command
• \$ : if the effective UID is 0, a #, otherwise a $
• \nnn : the character corresponding to the octal number nnn
• \\ : a backslash
• \[ : begin a sequence of non-printing characters, which could be used to embed a terminal control sequence into the prompt
• \] : end a sequence of non-printing characters

the SP1 value is stored in /etc/bash.bashrc at first i didn't have that file so i just copy the one in my other machine and it worked perfect. here is the file:

([[ -z ${CYG_SYS_BASHRC} ]] && CYG_SYS_BASHRC="1") || return

# If not running interactively, don't do anything

# Set a default prompt of: user@host and current_directory

Enabling DISPLAY environment variable for X11 forwarding from cygwin

I want to do this so I can forward commands to gnuplot from a shell script i have on cygwin, the steps where taken from the web[1,2].

Make sure you have the x11 packages installed in your cygwin and go to step 3, if not start from 1

1. Run the Cygwin installer (You can obtain cygwin from here: http://www.cygwin.com/setup.exe . 
2. At the package list, select to install all packages that are under the X11 category. Click next, accept all the dependencies, and install.
3. In the  Cygwin shell, run startxwin  
4. In your Cygwin shell, run export DISPLAY=:0.0.

You'll need to repeat step 3 every time you reboot your computer, and step 4 every time you open a new Cygwin shell (or just run echo "export DISPLAY=:0.0" >>~/.bash_profile to have it run automatically whenever you create a new shell).
