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 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
|
...
Spectre gives you Out of Memory Errors
| No Format |
|---|
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:
| No Format |

Mem Used: 579124 kB (Memory Exhausted)

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:
| No Format |
|---|
#
# 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:
| No Format |
|---|
#
# 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:
| No Format |
|---|
#
# Set Path
#
set path = ( $PATH \
$dfiiPath \
$assuraPath \
$anlsPath\
$confrmlPath\
$emgrPath\
$etPath\
$etsPath\
$extPath\
$iusPath\
$ifvPath\
$iusPath\
$mmsimPath\
$pacificPath\
$rcPath\
$socPath\
$spbPath \
$ctosPath )
