Chapter 6: Using NC-VHDL with Synopsys ModelsSimulator Configuration Guide1. Set the LMC_HOME environment variable to point to the location of yourSmartModel, FlexModel, or DesignWare Memory Model installation tree, asfollows:% setenv LMC_HOME path_to_models_installation2. Set the LM_LICENSE_FILE or SNPSLMD_LICENSE_FILE environment variableto point to the product authorization file, as shown in the following example:% setenv LM_LICENSE_FILE path_to_product_authorization_file% setenv SNPSLMD_LICENSE_FILE path_to_product_authorization_fileYou can put license keys for multiple products (for example, FlexModels andDesignWare Memory Models) into the same authorization file. If you need to keepseparate authorization files for different products, use a colon-separated list(UNIX).CautionDo not include la_dmon-based authorizations in the same file with snpslmdbasedauthorizations. If you have authorizations that use la_dmon, keepthem in a separate license file that uses a different license server (lmgrd)process than the one you use for snpslmd-based authorizations.3. Make sure that NC-VHDL is set up properly in your environment. See the NC-VHDL Simulator Configuration Guide for details.4. Depending on your platform, set your load library variable to point to the platformspecificdirectory in $LMC_HOME, as shown in the following examples:Solaris 32-bit:% setenv LD_LIBRARY_PATH $LMC_HOME/lib/sun4Solaris.lib:$LD_LIBRARY_PATHLinux:% setenv LD_LIBRARY_PATH $LMC_HOME/lib/x86_linux.lib:$LD_LIBRARY_PATHAIX:% setenv LIBPATH $LMC_HOME/lib/ibmrs.lib:$LIBPATHHP-UX 32-bit:% setenv SHLIB_PATH $LMC_HOME/lib/hp700.lib:$SHLIB_PATHSPARC64% setenv LD_LIBRARY_PATH $LMC_HOME/lib/sparc64.lib:$LD_LIBRARY_PATHHP64% setenv SHLIB_PATH $LMC_HOME/lib/hp64.lib:$SHLIB_PATH108 Synopsys, Inc.

Simulator Configuration GuideChapter 6: Using NC-VHDL with Synopsys ModelsRunning 32-bit Models on 64-bit PlatformsIf you want to run 32-bit Synopsys models or tools on a 64-bit HP-UX or Solarisplatform, set the LMC_USE_32BIT environment variable to any value before invokingthe tool, as shown in the following example:% setenv LMC_USE_32BIT 1The LMC_USE_32BIT environmental variable is a “set/no-set” variable. That is, youcan set it to any value (even zero) to turn on 32-bit support on a 64-bit platform. If youdo not set it at all, the default condition is 32-bit models on 32-bit platforms, or 64-bitmodels on 64-bit platforms. You only set this environmental variable (to any value)when you are on a 64-bit platform using 32-bit models and simulators.Using SmartModels with NC-VHDLTo use SmartModels with NC-VHDL, follow this procedure:1. Make sure NC-VHDL is set up properly and all required environment variables areset, as explained in “Setting Environment Variables” on page 107.2. Add the following line to your cds.lib file to specify the logical library sm_libraryfor SmartModels, as shown in the following example:DEFINE sm_library ./sm_library3. Run the ncshell utility to generate a wrapper for the model that you want to use, asshown in the following example:% ncshell -import swift -into vhdl model -nocompile -work sm_libraryThis step produces a wrapper file (model.vhd) and a component declaration(model_comp.vhd) for the specified model in the sm_library work directory.If you want to generate wrappers for all SmartModels in your $LMC_HOME tree,add the -all switch to the ncshell invocation. In this case, ncshell creates one file(shell.vhd) that contains all the model wrappers and another file (component.vhd)that contains the component declarations.4. Add LIBRARY and USE statements to your testbench:library sm_library;use sm_library.component.all;5. Instantiate SmartModels in your design using the wrapper files that you generated inStep 3. For information on required configuration parameters and instantiationexamples, refer to “Using SmartModels with SWIFT Simulators” on page 18.October 6, 2003 Synopsys, Inc. 109
