General guide

Working in the computer class (AK-213fg)

1. Input you username and password
2. Open terminal window
3. Work!

Working in Unix environment outside TUT (if firewall allows…)

• In the (X)terminal window log in the lab network through security protocol SSH “ssh –l <loginname> aragorn.cc.ttu.ee”

Tools usage

• For simulation and synthesis we use programs from companies Synopsys and Mentor Graphics. In order to use them you need to delete comment at the beginning of row “setenv SYNOPSYS” in the file .cshrc, this file you can find in your root directory. If there is not such row inside this file you should add it. The same rule works for the row “setenv MENTOR”. (don’t forget to open the new terminal window!).
• To edit your files you can use local text editor xemacs or textedit. To use xemacs you may need to add the row “setenv SPARWORKS” into .cshrc file. To see the syntax of VHDL inside xemacs you need to copy ~lrv/.emacs to your root directory (make it before xemacs opening). [>cp ~lrv/.emacs .]

Before beginning to work it is advisable to perform following actions: (because Synopsys creates during its work a lot of working files, which is not nice to hold in root directory).

1. Create subdirectory to work with Synopsys (for example hdl) and move there. [>mkdir hdl] [>cd hdl]
2. Copy into this subdirectory file ~lrv/hdl/.synopsys_vss.setup [>cp ~lrv/hdl/.synopsys_vss.setup .]
3. Inside this subdirectory create one more subdirectory WORK.sim [>mkdir WORK.sim]

There are only 9 Synopsys licenses and 35 Mentor Graphics licenses, therefore with many users try to use programs efficiently.

· To read on-line documentation of Synopsys use command synhelp

· Some necessary tools:

o To snap some windows or areas use snapshot program.

o You can use xfig to edit graphics.

Exercise reports

Exercise report first page must contain name of the subject, name of the student, student’s code and date.

Report must contain:

• Solution description and explanation;
• Analysis of the results (what tests are selected and why);
• The results of simulations (waveform diagrams);
• Answers to the questions and evaluation of the results.

It is recommended to send reports by e-mail to the address uljana@pld.ttu.ee. If you have your own homepage, it is enough to give a link to the page with the report.
