Cadence won't start, doesn't exit cleanly, or complains about lock files
- Ensure you are not running Cadence anywhere (i.e. research server, linuxpool, amdpool, etc.)
- To find your cadence processes run the command
No Format |
---|
ps -elf | grep cadence | grep <login id> |
For example:
No Format |
---|
ps -elf | grep cadence | grep yyy33 |
You can omit the "| grep cadence" just to see all your processes.
- You can kill all your processes, including your login shell, by typing
No Format |
---|
kill -9 -1 |
- Check your processes again per step 2 until you are sure your cadence processes are gone.
- You may need to clean up Cadence lock files. You can run the command:
No Format |
---|
find . -name .snapshot -prune -o -name *cdslck* -exec rm {} \; |
If you still have issue, repeat this process and try the following:
No Format |
---|
$ kill -9 -1
$ mkdir backup
$ mv .cds* Cadence* .cadence cds* CDS* .libmgr .libsel backup
$ exit
|
When starting Cadence, an error indicates that cds.lib can not be read.
...
Various security updates affect NFS periodically. You need to set the environment variable DD_DONT_DO_OS_LOCKS before starting cadence.
Example:
Code Blocknoformat |
---|
prompt> setenv DD_DONT_DO_OS_LOCKS TRUE prompt> icfb |
Spectre Memory Errror
Spectre gives you Out of Memory Errors
Code Blocknoformat |
---|
Warning from spectre during PNoise analysis `pnoise'. WARNING (SPCRTRF-15142): The 'maxsidebands' parameter in analysis `pnoise' has the unusually small value of 5. Using too small a value degrades accuracy because this parameter controls the amount of noise folding considered. |
Using the operating-point information generated by PSS analysis `pss', you get:
Code Blocknoformat |
---|
Mem Used: 579124 kB (Memory Exhausted)
|
It was found by Xiao Wang that if you pass the "-64" command line switch to the simulation, the problem goes away. The "-64" command line switch tells Spectre to use the 64 bit version.
Setting up Cadence Environment (TCSH)
You have to set the application install directory environment variables for the tools you want to use. Below is an example for all of them:
Code Blocknoformat |
---|
#
# Path to application install directories
#
set CDSHOME = /opt/cadence/ic
set ASSURAHOME = /opt/cadence/assura
set ANLSHOME = /opt/cadence/anls
set ASSURAHOME = /opt/cadence/assura
set CONFRMLHOME = /opt/cadence/confrml
set EMGRHOME = /opt/cadence/emgr
set ETHOME = /opt/cadence/et
set ETSHOME = /opt/cadence/ets
set EXTHOME = /opt/cadence/ext
set ICHOME = /opt/cadence/ic
set IFVHOME = /opt/cadence/ifv
set IUSHOME = /opt/cadence/ius
set MMSIMHOME = /opt/cadence/mmsim
set PACIFICHOME = /opt/cadence/pacific
set RCHOME = /opt/cadence/rc
set SOCHOME = /opt/cadence/soc
set SPBHOME = /opt/cadence/spb
set CTOSHOME = /opt/cadence/ctos
|
Then you set paths to the executables for each of the apps, for example:
Code Blocknoformat |
---|
#
# Path to Cadence Executables
#
set dfiiPath = ($CDSHOME/tools/bin $CDSHOME/tools/dfII/bin)
set assuraPath = ($ASSURAHOME/tools/bin $ASSURAHOME/tools/dfII/bin)
set anlsPath = ( $ANLSHOME/tools/bin $ANLSHOME/tools/dfII/bin )
set confrmlPath = ( $CONFRMLHOME/tools/bin $CONFRMLHOME/tools/dfII/bin)
set emgrPath = ( $EMGRHOME/tools/bin $EMGRHOME/tools/dfII/bin)
set etPath = ( $ETHOME/tools/bin $ETHOME/tools/dfII/bin )
set etsPath = ( $ETSHOME/tools/bin $ETSHOME/tools/dfII/bin )
set extPath = ( $EXTHOME/tools/bin $EXTHOME/tools/dfII/bin )
set ifvPath = ( $IFVHOME/tools/bin $IFVHOME/tools/dfII/bin )
set iusPath = ( $IUSHOME/tools/bin $IUSHOME/tools/dfII/bin )
set mmsimPath = ( $MMSIMHOME/tools/bin $MMSIMHOME/tools/dfII/bin )
set pacificPath = ( $PACIFICHOME/tools/bin $PACIFICHOME/tools/dfII/bin )
set rcPath = ( $RCHOME/tools/bin $RCHOME/tools/dfII/bin )
set socPath = ( $SOCHOME/tools/bin $SOCHOME/tools/dfII/bin )
set spbPath = ( $SPBHOME/tools/bin SPBHOME/tools/dfII/bin )
set ctosPath = ( $CTOSHOME/tools/bin $CTOSHOME/tools/dfII/bin )
|
Then you have to update your actual UNIX path:
Code Blocknoformat |
---|
# # Set Path # set path = ( $PATH \ $dfiiPath \ $assuraPath \ $anlsPath\ $confrmlPath\ $emgrPath\ $etPath\ $etsPath\ $extPath\ $iusPath\ $ifvPath\ $iusPath\ $mmsimPath\ $pacificPath\ $rcPath\ $socPath\ $spbPath \ $ctosPath ) |
