Pictorial introduction to using Cadence & Subversion

By Poojan Wagh | Published: September 5, 2008

I previously blogged about some scripts I use to help Cadence & Subversion be more compatible. I received some feedback that the scripts were incomplete and came without any usage model. So, I went through an excercise to document the scripts and to make sure they were complete.

Untar the CDSVN.tar file. It will create a directory called CDSVN

[wagh@porthos ~/example]$ tar xvf ~/cdsvn2.tar
  CDSVN/
  CDSVN/cdsLibMgr.il
  CDSVN/bin/
  CDSVN/bin/add
  CDSVN/bin/unlock
  CDSVN/bin/savesvn
  CDSVN/bin/fixtilde
  CDSVN/bin/unlockify
  CDSVN/bin/lock
  CDSVN/bin/lockify
  CDSVN/bin/cdsignore
  CDSVN/svnAddCV.il
  CDSVN/svnAddCell.il
  CDSVN/svnCopyCV.il
  CDSVN/svnCopyCell.il
  CDSVN/svnCopyTrigger.il
  CDSVN/svnLockCV.il
  CDSVN/svnLockCell.il
  CDSVN/menus/
  CDSVN/menus/schematic.menus
  CDSVN/menus/layEdit.menus
  CDSVN/README
  CDSVN/COPYING
  CDSVN/svn.cdsinit
  CDSVN/cadence_ignores.txt
  CDSVN/example.cdsinit

Set up Subversion with a new repository for Cadence

  [wagh@porthos CDSVN]$ svnadmin create ~/examplerepo

Modify svn.env script to point to your subversion repository

Change the line:

setenv SR file:///home/user/examplerepo

to list your

~/examplerepo

(for example)

Set up environment variables

cd CDSVN
[wagh@porthos CDSVN]$ source svn.env
What this script just did:
PATH = /usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/home/wagh/example/CDSVN/bin
If you haven't already, please edit this script to change the variable SR to point to a subversion repository
SR = file:///home/user/examplerepo
[wagh@porthos CDSVN]$ cd ..
[wagh@porthos ~/example]$

Import your work area (

CDSVN

) into the repos

[wagh@porthos CDSVN]$ svn import CDSVN $SR/trunk -m "Importing Cadence area into trunk"
