Title: can't plot any data
Post by apprentice on May 7th, 2009, 7:37pm

Hi Gurus,
 I tried a rfExample - LNA simple from Cadence spectreRF simulator. However, I was not successful to even plot a single figure.

Simulation runs and shows ready.
But plot doesn't show up. please refer to the screen shot.
in case the jpg can't be posted, the message is :

"There is no analysis data found or selected."


thanks for any suggestion on what I should check and try.

What waveform viewer are you using?  Are you using ADE?  Can you see a results directory created by Spectre?

Title: Re: can't plot any data
Post by apprentice on May 8th, 2009, 1:36pm

thanks for your reply.
I use analog design environment. Assume ADE is the acronym.
Looks like I don't have a result directory. Should it under .../spectre? same level as .../spectre/schematic?

I'm checking my environment variables - PATH, etc.

After simulation, or even during, go to Results->Select and schematic should be one of the options. Sometimes the direct plot form doesn't load the results.

Your simulation directory is set from ADE->Setup->Simulator/Directory/Host or from the environment variable (in .cdsenv not in your path!)

asimenv.startup projectDir string "/some_folder"

Then your results are saved in /some_folder/cellname/spectre/psf

Don't mean to sound insulting, but did you actually *run* the simulation? You don't have a spectre.out file (output log) in your .../spectre/psf folder.

Post by apprentice on May 8th, 2009, 8:44pm

Thanks Oermens. Any potential solution/correction is welcome.

1 Do I need vi .cdsenv at the very beginning, i.e.,  before running icfb?
  vi the .cdsenv to include the project directory - .../lnaSimple (which has the sub directory .../schematic) .
 
   My current .cdsenv is a default one. no asimenv.startup as shown below:
"ddserv showWhatsNew string "4.4.3"
spectre.envOpts firstRun boolean nil
spectre.envOpts controlMode string "batch"
asimenv showWhatsNew string "4.4.3"
asimenv showWhatsNew string "4.4.6"
asimenv showWhatsNew string "4.4.3"
asimenv showWhatsNew string "4.4.6"
asimenv showWhatsNew string "4.4.3"
asimenv showWhatsNew string "4.4.6"
asimenv showWhatsNew string "4.4.3"
asimenv showWhatsNew string "4.4.6"
asimenv showWhatsNew string "4.4.3"
asimenv showWhatsNew string "4.4.6"
asimenv showWhatsNew string "4.4.3"
asimenv showWhatsNew string "4.4.6"
asimenv showWhatsNew string "4.4.3"
asimenv showWhatsNew string "4.4.6"
asimenv showWhatsNew string "5.1.0"
asimenv showWhatsNew string "4.4.6"
asimenv showWhatsNew string "5.1.0"
asimenv showWhatsNew string "5.0.0"
asimenv showWhatsNew string "4.4.6"
asimenv showWhatsNew string "5.0.0"
asimenv showWhatsNew string "5.1.0"
"

2. in my case, the cellname is lnaSimple

3. what I did is netlist and run and ADE show "ready" after 1 minute.  I guess I run the simulation.

4. confused by spectrRF document (page 257-258 ver5.1.41 nov.2005)
 
   setenv CDS_rfExamples 'cds_root icms'   (i'm using icfb. shall i change icmst to icfb? Does "cds_root" depends on my installation?
   

Shall I include the path to .cdsinit or .cshrc?
I tried in .cshrc with setenv PATH. but cause problem.
path = ( $MMSIMHOME/tools/bin  $MMSIMHOME/tools/dfII/bin \         $CDSHOME/tools/bin  $CDSHOME/tools/dfII/bin \         $CDSHOME/tools/java $CDSHOME/tools/java/bin $path )

I found no such directory like .../java. my installation shows  ../jre.

really confused by the environment.

thanks a lot for some hints!

You don't have to edit .cdsenv, you can set the project directory in ADE as I mentioned previously (Setup->Simulator/Directory/Host). In my case, I have all my results stored in /opt/simulation/ and when I run simulation using lnaSimple (for example), spectre will create the results folders in /opt/simulation/lnaSimple/... So you just have to specify the base directory of the simulation results.

Also are you setting your environment to append the .cdsenv file upon exit? you have alot of duplicate entries which can cause confusion when loading icfb. If asimenv.startup projectDir is not defined, spectre will use the default location which i believe is $PWD/simulation. You can refer to ../IC/doc/anasimhelp/anasimhelp.pdf for information about this and other analog environment variables that can be set in .cdsenv.

Firstly, what type of analysis have you set up? If your analysis pane is empty then no wonder you aren't getting results. Please attach your input.scs file from /simulation/lnaSimple/spectre/schematic/netlist folder. After hitting netlist and run, do you get warnings or errors in icfb? What is cadence doing during that one minute?

cds_root will find the path to the argument. since icfb and icms are in the same folder (.../IC/tools/dfII/bin) it shouldn't matter. Also be sure to use ` and not ' around the command. rfExamples folder should be set in cds.lib not as an environment variable unless your cds.lib has something along the lines of DEFINE rfExamples $CDS_rfExamples. Simpler way is to add this line to cds.lib (some useful example directories)

#EXAMPLE LIBRARIES
DEFINE US_10ths $CDS_HOME/tools/dfII/samples/cdslib/sheets/US_10ths
DEFINE rfLib $CDS_HOME/tools/dfII/samples/artist/rfLib
DEFINE rfExamples $CDS_HOME/tools/dfII/samples/artist/rfExamples
DEFINE pllMMLib $CDS_HOME/tools/dfII/samples/artist/pllMMLib
DEFINE pllLib $CDS_HOME/tools/dfII/samples/artist/pllLib
DEFINE passiveLib $CDS_HOME/tools/dfII/samples/artist/passiveLib
DEFINE bmslib $CDS_HOME/tools/dfII/samples/artist/bmslib
DEFINE ahdlLib $CDS_HOME/tools/dfII/samples/artist/ahdlLib
DEFINE aExamples $CDS_HOME/tools/dfII/samples/artist/aExamples
DEFINE avTech $CDS_TOP_DIR/ASSURA/tools/assura/etc/avtech/avTech
DEFINE functional $CDS_HOME/tools/dfII/etc/cdslib/artist/functional

these variables, CDS_HOME and CDS_TOP_DIR are specific to my site, maybe your variables are different. CDS_HOME is the same as result of cds_root icfb. CDS_TOP_DIR is the directory where all your cadence tools are installed (i.e. CDS_HOME can also be CDS_TOP_DIR/IC and MMSIMHOME can be CDS_TOP_DIR/MMSIM, etc).

are you using .cshrc designed for the same version of IC that you are using?

Title: Re: can't plot any data
Post by apprentice on May 8th, 2009, 9:39pm

I post the netlist and log first. I'm trying other suggestion.
Thanks.

1. the netlist  (remove this duplication, see below the recreated one)


2. .cshrc version seems match IC version I'm using. See below. I'm using SUNOS
 #
# Variables: ICVer     = ICFB version
#            ASSURAVER = Assura version
#            CalVer    = Calibre version

alias cdsdoc cdnshelp

set CADOS = `uname | tr '[a-z]' '[A-Z]'`

echo "OS      =" $CADOS

if("$CADOS" =~ *SUNOS*) then

  #setenv ICVer IC446
  #setenv ICVer IC446_MSR11
  #setenv ICVer IC5033
  #setenv ICVer IC5033usr3r4
  setenv ICVer IC5141_USR4
  setenv MMSIMVer MMSIM60

  #setenv ASSURAVER ASSURA313usr1
  #setenv ASSURAVER ASSURA316

  setenv CalVer cal_2005.1_10.20
 
endif

3. setenv PATH   in .cshrc
    SHELL=/bin/tcsh
    when I try
setenv PATH $PATH:$MMSIMHOME/tools/bin:$MMSIMHOME/tools/dfII/bin:$CDSHOME/tools/bin:$CDSHOME/tools/dfII/bin:


after run .cshrc,   it shows:
Bad : modifier in $ ($).

    Do I keep other PATH configurations when I append the new PATH configuration?

Sorry my syntax was also wrong, i was mixing zsh and csh syntax. Refer http://root.cern.ch/root/EnvVars.html. So you should be using

set path = ( $path $MMSIMHOME/tools/bin $MMSIMHOME/tools/dfII/bin $CDSHOME/tools/bin:$CDSHOME/tools/dfII/bin $CDSHOME/tools/java $CDSHOME/tools/java/bin ) as before. Make sure everything is on a single line. You don't set MMSIMHOME or CDSHOME in you .cshrc, are you running another script to set these variables, or this is just small part of your .cshrc?

This can also be the case if the simulation is not successful. I'm not sure why the simulation proceeds without include files. Are you using one of the gpdk's? I think alot of the appnotes are written for gpdk180, in which case you should also include its model file. If you installed the kit correctly, this should be taken care of by the .cdsenv template of the pdk, and you should set the environment variable CDS_LOAD_ENV=CWDElseHome (loads CWD/.cdsenv if it exists, or else ~/.cdsenv, if it exists). As requested, please attach your input.scs and spectre.out files.

No. This example doesn't use "gpdk".

Include "$CDS_INST_DIR/tools/dfII/samples/artist/models/spectre/rfModels.scs" as model file.

It seems he has a model file specified, otherwise he would receive the message in output log:


Code:

Use the Simulation->Output Log menu for more information.


I loaded the lnaSimple example and simulated using pss analysis and found no errors. I followed pancho_hideboo's instruction to load $CDS_INST_DIR/tools/dfII/samples/artist/models/spectre/rfModels.scs as the model file. I don't know which document you refered to in a previous post, but the voltage gain should be 10dB if my simulation is correct?

I just reviewed this document regarding simulating low noise amplifiers, if you follow the instructions carefully you should not encounter any errors. Disregard my previous comment about CDS_rfExamples, I did not know its purpose before. Your .cshrc should include the following

setenv CDS_rfExamples ‘cds_root icms‘
setenv CDS_Netlisting_Mode "Analog"
setenv MMSIMHOME <path_to_MMSIM_simulators>
setenv CDSHOME <path_to_IC_simulators>
setenv path = ( $MMSIMHOME/tools/bin $MMSIMHOME/tools/dfII/bin $CDSHOME/tools/bin $CDSHOME/tools/dfII/bin $CDSHOME/tools/java $CDSHOME/tools/java/bin $path )

Assume you are in a fresh directory for running icfb and you didn't modify any cds.lib or copy the rfExamples folder. Type these commands in the folder

cp -rf $CDSHOME/tools/dfII/samples/artist/rfExamples ./
echo DEFINE my_rfExamples $PWD/rfExamples >> cds.lib

After launching icfb and loading lnaSimple schematic and invoking ADE, go to Setup>Simulator/directory/host and set the project directory to a location which you have write permission for. If holding onto results is not important, you can use /tmp. Go to Setup>Model Libraries and add <CDSHOME>/tools/dfII/samples/artist/models/spectre/rfModels.scs as the model file. <CDSHOME> is replaced with the value of $CDSHOME. Proceed with simulation as specified in users guide.

I see the problem. You have to move that line in .cshrc to be after the path definition. Otherwise cds_root will not be found because it is located in $MMSIMHOME/tools/bin which is not in the path when cds_root is initially called. See below:

setenv CDS_Netlisting_Mode "Analog"
setenv MMSIMHOME /usr/eda/cds/MMSIM60/
setenv CDSHOME /opt/eda/cds/IC5141_USR4
setenv path = ( $MMSIMHOME/tools/bin $MMSIMHOME/tools/dfII/bin $CDSHOME/tools/bin $CDSHOME/tools/dfII/bin $CDSHOME/tools/java $CDSHOME/tools/java/bin $path )
setenv CDS_rfExamples ‘cds_root icms‘

Aside: MMSIM60 and IC5141USR4 are very old. Update your tools if possible.

What shell are you using? Why do you need to source .cshrc if its in your home folder? If you are using another shell than (t)csh why not just write the script for that shell? Does your network admin have any idea how to set up unix environment for cadence?

SHELL=/bin/tcsh

no syntax error with "  setenv CDS_rfExamples `cds_root icms` "

but env command show CDS_rfExamples is not there.

then I tried " > setenv CDS_rfExamples `cds_root icms`" .
then env show it is defined.

Yes because it is already enabled. Go to Tools>Results Browser, then File>Open Results and browse to /home/cdssim/simulation/lnaSimple/spectre/schematic/psf and see if results are there. Post spectre.out and input.scs to see where the problem exists.

so far one problem is that spectre.out can not be generated after simulation.

Have you ever run Cadence Spectre correctly using other circuits than rfExample ?
Do you surely have SpectreRF's License or enough number of Tokens for MMSIM ?

Try to run Spectre from unix command line without using ADE.

We should have SpectreRF license in our floating licenses.
How to check it?
 

I only used "option - > license " check schematic users. It seems licenses are automatically checked out when I open schematic and ADE.

Will double check after our IT finishing re-installation.

I also tried a DC analysis which shows similar problem - no output.

Go to the ~/simulation/lnaSimple/spectre/schematic/netlist directory in UNIX and type "./runSimulation" (there should be a script called runSimulation in the directory).

It may be that there is some problem with shared libraries or something similar that means that the simulator can't even start - hence a log file is not being produced.

Then tell us what it says...

Regards,

Andrew.

Hi Andrew,
  The above is what it says.
  I will keep trying until we have new system.  

thanks

hi all,

  I just got new system. The RF examples can run without problem.

 

thanks
