Simulator Configuration Guide for Synopsys Models

Simulator Configuration GuideChapter 3: Using ModelSim Verilog 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 ModelSim VerilogSmartModels work with ModelSim Verilog using a PLI application called LMTV that isdelivered in the form of a swiftpli_mti shared library in $LMC_HOME/lib/platform.lib.For information on static linking LMTV, see “Static Linking with LMTV” on page 268.To use SmartModels with the prebuilt swiftpli_mti, follow this procedure:1. Make sure MTI Verilog is set up properly and all required environment variables areset, as explained in “Setting Environment Variables” on page 59.2. Instantiate SmartModels in your design, defining the ports and defparams asrequired. For details on the required SWIFT parameters and SmartModelinstantiation examples, refer to “Using SmartModels with SWIFT Simulators” onpage 18.3. Map your work library as shown in the following example:% vlib work% vmap work workThis step produces a modelsim.ini file.4. Edit the modelsim.ini file to uncomment the Resolution statement, and set theresolution value to 100ps, as shown in the following example.Resolution = 100psOctober 6, 2003 Synopsys, Inc. 61
