Chapter 4: Using ModelSim VHDL with Synopsys ModelsSimulator Configuration GuideUsing DesignWare Memory Models withModelSim VHDLDesignWare Memory Models (DWMM) are SWIFT-compatible binary simulationmodels that have an _mx extension (for example, model_mx).To use DWMM models with ModelSim-VHDL, follow these steps:1. Make sure ModelSim VHDL is set up properly and all required environmentvariables are set, as explained in “Setting Environment Variables” on page 73.2. Map the slm_lib logical library, as shown in the following example:% vlib slm_lib% vmap slm_lib slm_libThis step also creates a modelsim.ini file in the current working directory.3. Open the modelsim.ini file in a text editor, and edit the line for Resolution, as shownin the following example:Resolution = 100psThen uncomment the libsm and libswift lines for the platform you are using:; ModelSim’s interface to Logic Modeling’s SmartModel SWIFT software;libsm = $MODEL_TECH/libsm.sl; libsm = $MODEL_TECH/libsm.dll; Logic Modeling’s SmartModel SWIFT software (HP 9000 Series 700); libswift = $LMC_HOME/lib/hp700.lib/libswift.sl; Logic Modeling’s SmartModel SWIFT software (IBM RISC System/6000); libswift = $LMC_HOME/lib/ibmrs.lib/swift.o; Logic Modeling’s SmartModel SWIFT software (Sun4 Solaris); libswift = $LMC_HOME/lib/sun4Solaris.lib/libswift.so; Logic Modeling’s SmartModel SWIFT software (Sun4 SunOS); do setenv LD_LIBRARY_PATH $LMC_HOME/lib/sun4SunOS.lib; and run "vsim.swift".; libswift = $LMC_HOME/lib/pcnt.lib/libswift.dll4. To create the model’s bit-blasted VHDL wrapper, run the ModelSim sm_entityscript, as shown in the following example:% $MTI_HOME/bin/sm_entity -c model_mx > model_mx.vhdThis step generates entity and component declarations for the model.NoteIf you want to use more than one DWMM model in your simulation, refer tothe “sm_entity Command Reference” on page 79.82 Synopsys, Inc.

Simulator Configuration GuideChapter 4: Using ModelSim VHDL with Synopsys Models5. Edit the generated model_mx.vhd file as follows. In the architecture section, add the“library ieee” line highlighted in the following example:architecture SmartModel of model_mx isattribute FOREIGN : STRING;attribute FOREIGN of SmartModel : architecture is "sm_init$MODEL_TECH/libsm.sl ; model_mx;beginend SmartModel;Also, at the end of the model_mx.vhd file, right after the “end component”statement, add the following highlighted line:end component;end comp;6. Compile the required Synopsys libraries into the slm_lib library, as shown in thefollowing examples:% vcom -93 -work slm_lib $LMC_HOME/sim/mti/src/slm_hdlc.vhd% vcom -93 -work slm_lib $LMC_HOME/sim/mti/src/mempro_pkg.vhd7. Add slm_lib LIBRARY and USE statements to your testbench:LIBRARY SLM_LIB;USE SLM_LIB.mempro_pkg.all;USE SLM_LIB.comp.all;8. Compile the model’s bit-blasted wrapper file (model_mx.vhd) into the slm_liblibrary, as shown in the following example:% vcom -93 -work slm_lib model_mx.vhd9. Create a bused wrapper for the model, as shown in the following example:% $LMC_HOME/bin/vsg -bit2bus vhdl model_mxThis step produces an output file named model_mx_bw.vhd.10. Edit the model_mx_bw.vhd file to add Library and Use statements, as shown in thefollowing example:LIBRARY SLM_LIB;USE SLM_LIB.comp.all;11. Compile the model’s bused wrapper, as shown in the following example:% vlib work% vcom -93 model_mx_bw.vhdOctober 6, 2003 Synopsys, Inc. 83
