Troubleshooting Guide: Frequently Asked Questions
General
My icfb window is frozen. How do I close it?
Open an Xterm window and type ps -u username and note the PID for icfb.exe. Execute the command kill -9
PIDno. This will close the cadence session. Delete the lock files if you have any.
How do I open the locked file in edit mode?
Go the folder in which your design files are stored. Depending on the number of views your design has, you
will have folders named schematic, symbol etc. Go to the folder schematic. You might see the files master.tag
pc.db prop.xx sch.cd% sch.cd- sch.cdb sch.cdb.cdslck etc. Leave the files master.tag pc.db prop.xx sch.cdb
and delete the other files (using rm filename). After this process you should be able to open the file in edit mode.
While doing this you should not have any other cadence session accessing the particular file in edit mode (for
example you might be accessing the file from home using Xwin).
How do I capture images for my lab report?
Refer to the Guide to Capturing Images.
Library Manager
Why can’t I see the default parts libraries in the manager?
When you first start Cadence, it creates a new library definition file called “cds.lib” in the directory you
launched it from. This links the necessary parts libraries to the Cadence workspace. If the file exists in the
launch directory but you aren’t seeing the parts libraries, check to make sure that the following line is in
“cds.lib”:
INCLUDE /opt/cds/local/cdssetup/cds.lib
If necessary, add this statement to the “cds.lib” using the text editor of your choice. To avoid having this
problem in the future, always launch Cadence from your class directory, and try not to edit, move or delete the
file unless you need to.
Why can’t I see any of my own design libraries in the manager?
Most likely, you have launched Cadence from a directory that does not contain all of your previous work. A
common mistake is to run icfb from your home directory (“/home/<username>/cadence”) and not your class
Cadence directory. Make sure you are running icfb from the correct place.
