2. Graduate Institute of Electronics Engineering, NTU Workstation  A powerful computer for massive tasks by multiple remote users concurrently  Multi-user multi-tasking  Must be stable and equipped with high-end CPU and memory  UNIX-like OS is most commonly used  Workstation used in this class: Leopard  Owned by Access IC Lab, GIEE  Intel Xeon 2.66GHz, 8 Cores, 26G Memory  OS: RedHat Enterprise 5 Linux p. 2 Yu-Hao ChenUsage of Workstation

3. Graduate Institute of Electronics Engineering, NTU Remote Computing by SSH  Since multiple users log on to the workstation simultaneously, every user should use their PC as the terminal and run their tasks through a protocol called SSH  In brief, we need two programs to log in  PuTTY: The terminal program  Xming: The window server for running GUI programs on workstation  Both are freeware p. 3 Yu-Hao ChenUsage of Workstation

4. Graduate Institute of Electronics Engineering, NTU PuTTY Download  Google “putty”  Download “putty.exe” p. 4 Yu-Hao ChenUsage of Workstation

5. Graduate Institute of Electronics Engineering, NTU PuTTY Setting (1/2)  putty.exe is actually the executable, so we can run it without installing it!  First, fill the host name and choose connection type p. 5 Yu-Hao ChenUsage of Workstation 1 2 4 3

6. Graduate Institute of Electronics Engineering, NTU PuTTY Setting (2/2)  Second, enable X11 and save the setting p. 6 Yu-Hao ChenUsage of Workstation 5 6 7 scroll up 8 9 10

7. Graduate Institute of Electronics Engineering, NTU Xming Download  Google “xming”  Download it p. 7 Yu-Hao ChenUsage of Workstation

8. Graduate Institute of Electronics Engineering, NTU Xming Installation  All press “OK” & “Next”  After installation, Windows may ask for firewall issue, press “Allow” p. 8 Yu-Hao ChenUsage of Workstation

9. Graduate Institute of Electronics Engineering, NTU Log into the Workstation  Every time when logging in …  Launch Xming first, and check the right-bottom status  Execute putty.exe, click “leopard” session and press “open” p. 9 Yu-Hao ChenUsage of Workstation 1 2 3

10. Graduate Institute of Electronics Engineering, NTU Basic Linux Commands (1/2)  man instruction_name: manual page  ls: List a directory’s contents  ls –a: List the hidden files  ls –aux: List all files with detailed information  cp: Copy files from one directory to another  cp source_file destination_file  cp –r source_dir destination_dir: Copy dictionary from one directory to another  mkdir dir_name: Make a new directory  pwd: Display your current path  vim filename: Text editor p. 10 Yu-Hao ChenUsage of Workstation

11. Graduate Institute of Electronics Engineering, NTU Basic Linux Commands (2/2)  cd dir_name: Change directory  cd ~: Go to your home directory  cd..: Go to upper directory  ps: Display process status by process identification number and name  kill –9 process_number: Terminate a running process  kill -9 1234  rm: delete files  rm -r: remove directory  tar: compress files  -cvf: for creating compressed file  -xvf: for extracting compressed file  mv: move or rename file  exit: turn the terminal off p. 11 Yu-Hao ChenUsage of Workstation

12. Graduate Institute of Electronics Engineering, NTU Tool Usage (1/2)  Command: tool p. 12 Yu-Hao ChenUsage of Workstation

13. Graduate Institute of Electronics Engineering, NTU Tool Usage (2/2)  Waveform viewer: nWave  Type “tool” -> “1” to source the environment settings for nWave  Type “nWave &” to launch  Verilog simulator: ncverilog  Type “tool” -> “2” to source the environment settings for ncverilog  Type “ncverilog +access+r [testbench.v] [design.v]” to run the simulation  Note nWave environment should be sourced before running the simulator! p. 13 Yu-Hao ChenUsage of Workstation

14. Graduate Institute of Electronics Engineering, NTU Other Tips  File transfer between workstation & PC  Use FTP software, recommend the software “filezilla” (freeware)  IP: leopard.ee.ntu.edu.tw, port 21  Use the workstation account to log in  Text editor for writing Verilog code  Recommend the software “notepad++” (freeware) p. 14 Yu-Hao ChenUsage of Workstation
