customizing Cadence
Jun 19^th, 2005, 12:20am

Hello,

I was wondering how and in what file I would have to make changes in order for Cadence to load user specific profiles.
I would like to change the path to the model libraries for the analog environment without having to go to ->setup ->model libraries and typing them in all the time. How can I tell cadence to load a new set of libraries on startup? I guess I have to edit the .cdsini file, but I don't know how. Also, I want cadence to automatically tick the "show categories" box in the Library Manager.

Thanks

Put this in your .cdsenv file:

Code:

asimenv.startup projectDir	string  "/tmp/simulation"

or from SKILL (e.g. .cdsinit ):

Code:

envSetVal(
  "asimenv.startup" "projectDir"  'string
  strcat("/tmp/simulation/" getShellEnvVar("USER"))
)

The second one uses the USER UNIX env var to make each person's simulation directory different to avoid you stamping on each others results.

Regards,

Andrew.

Thanks Andrew and Paul. The cdsdoc is very useful but a rather large document and things tend to be hard to find if you're not sure what to look for. Your tip with the asimenv.startup variables helped a lot.
One thing I have not figured out yet is how to load the model libraries, i.e. /local/...../cmos53.scs and define a section. I had a look at the variable "modelpath" but that I could not get to work with asimenv.startup and it did not tell me how to define sections. Any tips?

Cheers,
Sven

For example: Code: envSetVal("spectre.envOpts" "modelFiles" 'string "/path/to/file1.scs;ss /path/to/file2.scs;ff") Regards, Andrew.

Is this possible? Cheers,

Sven,

The default .cdsenv settings for spectre would normally have veriloga in the view lists:

Code:

spectre.envOpts stopViewList    string  "spectre"
spectre.envOpts switchViewList  string  "spectre cmos_sch cmos.sch schematic veriloga ahdl"

Which would be the following in SKILL:

Code:

envSetVal("spectre.envOpts" "stopViewList" 'string  "spectre")
envSetVal("spectre.envOpts" "switchViewList" 'string "spectre cmos_sch cmos.sch schematic veriloga ahdl")

So presumably it's already set somewhere in your environment?

Or perhaps you just meant that you wanted to change the order of the view list to put veriloga earlier in the list?

Regards,

Andrew.
