复杂的安装说明，不过搞定。完美破解！！
CADENCE SPB V15.2 好软件，再安装一次也值得。：）

#  ************************************************
#  * Install notes follow, License info are below *
#  ************************************************
#
#   - Edit this license file and replace the "hostname" field below with your computer hostname
#   
#   - Create 2 environment variables:          a) LM_LICENSE_FILE
#                                              b) CDS_LIC_FILE
#     assign to both variable this value =>    5280@{your host name}
#     note under win9x, use autoexec.bat (SET LM_LICENSE_FILE=5280@{your host name})
#
#   - Install any Cadence Licence Manager from any cadence cdroms (ie LDV, PSD)
#   
#   all the next operations suit the SPB 15.2 installation.
#
#
#   - Feed the CD1, run setup.exe if your autorun feature is disabled
#
#   - Select "Set-Up Licensing" and point this license file when prompted about a license file
#
#   - Ignore the msg about the license can't be parsed if ther's any, this msg is fake , the license manager is already 
#     running perfectly ( poor cadence coders ;D )
#
#   - Once this License Manager installation is done, just select Install Products
#
#   - when prompted about controlfile.txt just makes the text box empty, and select items manualy...
#
#  
#   - Insert the cd2 when prompted
#
#   - If you installed ConceptHDL schemtic entry editor, u may install the librairies from the cd3
#     and if u don't wanna use concept HDL at all, u just burnt a cd for nothing, :D, isn't that funny!
#
#   Last step, if the software ask you about a reboot, u should really reboot!
