LAM File Locations

The LAM file generated as part of the library conversion process is stored in the following location.

• library/.cadence/dfII/cph/lam/cph.lam

During LAM initialization, this file is imported for each library defined in the library definitions file, cds.lib.

The system then searches the locations defined in the setup.loc file for any other library.lam file and loads the first one it finds. The settings in the library.lam file override the settings in the library/.cadence/dfII/cph/lam/cph.lam file.

Example

The default setup.loc file is

.                       current working directory always searched first
@LIBRARY                look in the design libraries for the file 
$CDS_WORKAREA           user workarea if defined 
$CDS_SEARCHDIR          this is set by various tools during tool startup 
$HOME
$CDS_PROJECT            project storage area, ignored if not defined 
$CDS_SITE               Site Setup Info - default is $CDS_INST_DIR/share/local 
$(compute:THIS_TOOL_INST_ROOT)/share    Cadence Default Setup Info 
 

For example, if a library called acpd is part of the library list, then during LAM initialization the system imports

• acpd/.cadence/dfII/cph/lam/cph.lam

And then checks for the following files

• ./.cadence/dfII/cph/acpd/lam/acpd.lam
• <alllibs- inc acpd>/.cadence/dfII/cph/acpd/lam/acpd.lam
• $CDS_WORKAREA/.cadence/dfII/cph/acpd/lam/acpd.lam
• ...

The system imports the first acpd.lam it finds and stops searching.
