Here is described the various steps on how to get a new Simulink model running on the new PCIX front-end computers (in this work the C1OMC at the 40m).
This writing is an glorified version of R. Ward's core entry in the 40m ilog ([http://www.ldas-sw.ligo.caltech.edu/ilog/pub/ilog.cgi?group=40m&date_to_view=11/06/2006&anchor_to_scroll_to=2006:11:06:17:34:27-rward entry]).
Directory structure
advLigo/
- This is the top working/modeling directory at a location to your taste.
/cvs/cds/caltech/target/c1omc/
- This is the frontend executable directory with the .rtl files.
/cvs/cds/caltech/chans/daq/
- This is the DAQ/Frame builder configuration directory on the PCIX front-end computer
Simulink model
Get the latest CVS code from ([http://ldas-sw.ligo.caltech.edu/cgi-bin/cvsweb.cgi/cds/?cvsroot=CDS LIGO/LSC CVS Repositories]) and place it in a suitable directory to work in. There are a few special Simulink modules for the ADC and DAC, LIGO filter modules, etc. which are required.
You can modify the Simulink model 'omc.mdl' appropriately. Make sure you have the correct dcuid number, as it could be wrong in CVS. For more info on this see [http://www.ligo.caltech.edu/%7Eaivanov/daq_handbook.html LIGO Data Acquisition Handbook], not sure how relevant this is to the C1OMC system.
The Simulink model can only have a three (3) character file name, which usually correspond to the system name here 'omc'. Also, the model itself can only be 1 layer deep (due to current restrictions). This means that in your Simulink model you have a top-layer, and you are only allowed to place a sub-layer in your model. You can have multiple sub-layers in your top-layer.
Making the FE code
To make the real-time linux executable, go to the top directory (advLigo/) and type:
make omc
Where 'omc' is the name of the Simulink model. This will generate a whole bunch of files and folders in the advLigo/target directory.
On the C1OMC front-end computer, remove the old target directories (c1omc and c1omcepics). Then copy the advLigo/target/omcepics to /cvs/cds/caltech/target/c1omcepics on the front-end computer.
Checking/Updating the Configuration files
Copy the file in advLigo/target/omcepics/db/C1/autoBurt.req to /cvs/cds/caltech/target/c1omcepics
Find the file 'omc.par' in advLigo/build/omcepics, and modify it with the following sed commands:
- s/%IFO%/C1/g
- Set the %IFO% to your local IFO-name.
- s/datarate = 16384/datarate = 32768/g
- Set the datarate to your local configuration.
- s/ifoid = 1/ifoid = 0/g
- Set the ifoid to your local ifo ID.
- s/rmid = 0/rmid = 1/g
- Set rmid to your local reflective memory ID.
See also [http://www.ligo.caltech.edu/%7Eaivanov/daq_handbook.html#Configuration%20Files|region Configuration Files] which has more details about these settings.
Then rename it as 'tpchn_C2.par', and place it in /cvs/cds/caltech/chans/param/ (why renaming?)
Location of the FE executable
Copy the generated front-end executable in advLigo/src/fe/omc/omcfe.rtl to /cvs/cds/caltech/target/c1omc/.
DAQ Channels
Take the file located at advLigo/src/epics/util/C1OMC.ini, modify it to suit your tastes, and place it in /cvs/cds/caltech/chans/daq/
Take the file located at advLigo/src/epics/util/C1OMC.txt, and put it in /cvs/cds/caltech/chans/
Restarting the FE
Use the procedure in the wiki to restart c1omc [http://lhocds.ligo-wa.caltech.edu:8000/40m/Computer_Restart_Procedures#c1omc c1omc restart]
