Hello Shaun under <version>/bin and <version>/tools/bin you have wrappers that permit to setup the good env . it’s not a good idea to bypass the wrapping system and use the architecture path same rule for snps and mg (except some funny tools ) rgds Charles Orbello From: mod...@li... <mod...@li...> On Behalf Of Laurent BESSON via lists.hpsf.io Sent: Monday, May 18, 2026 2:32 PM To: Sha...@us...; Xavier Delaruelle <xav...@gm...> Cc: Environment Modules usage and discussion. <mod...@li...> Subject: Re: [Modules] Conflict with Tcl libraries in LD_LIBRARY_PATH Hello Shaun, I checked the Module we use internally to set up Cadence Xcellium for version 25.09 and we do not modify LD_LIBRARY_PATH. Here what « module show » says about this module : /tool/modules/cadence/xcelium/25.09_e334: conflict cadence/xcelium module load cadence/licensing/licences module-whatis {XCELIUM 25.09_e334 setup} setenv VRST_HOME /tool/cadence/xcelium/25.09_e334 setenv XCELIUM_HOME /tool/cadence/xcelium/25.09_e334 prepend-path PATH /tool/cadence/xcelium/25.09_e334/bin:/tool/cadence/xcelium/25.09_e334/tools/bin Have you tried removing LD_LIBRARY_PATH prepend command from your Module setup and see if tool still behaves correctly ?

Just for additional info, the offending tool module does the following : %> module display xcelium/test ------------------------------------------------------------------- /sw/modules/modulefiles/cad/cdn/xcelium/test : module-whatis {Xcelium modules environment} prereq socionext prepend-path PATH $CADROOT/cdn/bin prepend-path PATH $CADROOT/cdn/org/xcelium/24.03.013/tools.lnx86/bin prepend-path PATH $CADROOT/cdn/org/xcelium/24.03.013/bin prepend-path LD_LIBRARY_PATH $CADROOT/cdn/org/xcelium/24.03.013/tools.lnx86/lib/64bit prepend-path LD_LIBRARY_PATH $CADROOT/cdn/org/xcelium/24.03.013/tools.lnx86/inca/lib/64bit prepend-path LD_LIBRARY_PATH $CADROOT/cdn/org/xcelium/24.03.013/lib ------------------------------------------------------------------- Where $CADROOT is set to “/sw” in the “socionext” module.

In /etc/environment-modules/initrc, add the following lines: module config quarantine_support 1 module config run_quarantine LD_LIBRARY_PATH Then restart a new shell session. It should protect the module execution from this interfering Tcl installation.
