First of all, the tools are only set up on mosis4.cse.ucsc.edu (for CMPE 222) or on any of the mada machines (for Jose and my research groups). You must run them remotely on the machines by exporting your X display:

Preparation

Create your SOE Account

https://support.soe.ucsc.edu/accounts

Install a VPN Client

https://its.ucsc.edu/vpn/installation.html

Connecting Remotely

From Linux/Unix

First of all, the tools are only set up on servers (waterdance.soe.ucsc.edu and riverdance.soe.ucsc.edu for CMPE222/223, your specific lab machine in CMPE125/CMPE126, or on any of the mada machines for the MASC and VLSI research groups).

You can run them remotely on the machines by exporting your X display: 

ssh -Y riverdance.soe.ucsc.edu

and you must have an X11 client on your computer. Suggested X11 clients are

  1. X11.app in OSX
  2. Xorg's XFree86 in Linux
  3. Xming in Windows

You can do this from home if you have a fast internet connection. Otherwise, you must use the computing labs.

From Windows

To display on a Windows machine, you should do below:

  1. Install Xming from https://sourceforge.net/projects/xming/
  2. Install Xming fonts from https://sourceforge.net/projects/xming/files/Xming-fonts/7.7.0.10/Xming-fonts-7-7-0-10-setup.exe/download
  3. Install putty, an SSH client from http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe
  4. Start Xming
  5. Start putty
  6. In the "SSH->Tunnels" page of putty, click on "Enable X forwarding"
  7. In the Session page of putty, write the hostname (riverdance.soe.ucsc.edu). You can also write your username like this, username@riverdance.soe.ucsc.edu. Hit "Save" to save the session for future use
  8. Hit "Open" to start your session

Now, any X application (e.g. xcalc) works by displaying to your local machine.

Setting up the CAD Tools

You can check your shell by typing: 

echo $0

Setup with bash

In your .bash_profile file, make sure you use our CAD tool setup: 

source /bsoe/software/set-paths.sh
source /projects/cmpe122/setup.sh (source /mada/software/setup.sh for VLSI-DA lab)

If you plan on using FreePDK45, you must also add this to the .bash_profile: 

export CDS_SITE=/bsoe/software/design-kits/FreePDK45/ncsu_basekit (source /mada/software/setup_freepdk45.sh for VLSI-DA lab)

Copy .bash_profile to .bashrc. 

cp .bash_profile .bashrc

You must now log out and log back in to get the new setup.

Setup with csh or tcsh

Run bash. These shells do not work and are not supported. You can request bash from ITS as your default shell or you can manually run "bash" each time. Or, as a quick hack, you can add this to your .tcshrc configuration file: 

export SHELL=/bin/bash; exec $SHELL

The above command will run a copy of bash every time you log in. **NOTE: Can someone verify this? My default shell isn't tcsh. I'm not sure if it will source your .profile/.bashrc files or not.
