Simulator Configuration Guide for Synopsys Models

Chapter 6: Using NC-VHDL with Synopsys ModelsSimulator Configuration Guide4. Generate a VHDL wrapper file for the model by invoking ncshell, as shown in thefollowing example:% ncshell -import swift -into vhdl model_fx -nocompile -work slm_lib5. Create a working directory and run flexm_setup to make copies of the model'sinterface and example files there, as shown in the following example:% $LMC_HOME/bin/flexm_setup -dir workdir model_fxYou must run flexm_setup every time you update your FlexModel installation witha new model version. Table 12 describes the FlexModel NC-VHDL interface andexample files that the flexm_setup tool copies.Table 12: FlexModel NC-VHDL FilesFile Name Description Locationmodel_pkg.vhdModel command procedure calls for HDLCommand Mode.workdir/src/vhdl/model_user_pkg.vhd Clock frequency setup and usercustomizations.workdir/src/vhdl/model_fx_comp.vhdmodel.vhdmodel_tst.vhdComponent definition for use with the modelentity defined in the SWIFT wrapper file. Thisis put in a package named “COMPONENTS”when compiled.A bus-level wrapper around the SWIFT model.This allows you to use vectored ports for themodel in your testbench. This file assumes thatthe “COMPONENTS” package has beeninstalled in the logical library “slm_lib”.A testbench that instantiates the model andshows how to use basic model commands.workdir/examples/vhdl/workdir/examples/vhdl/workdir/examples/vhdl/6. Update the clock frequency supplied in the model_user_pkg.vhd file in yourworking directory to correspond to the desired clock period for the model. After yourun flexm_setup this file is located in:workdir/src/vhdl/model_user_pkg.vhdwhere workdir is your working directory.7. Create a logical library named slm_lib. The default physical library mapping for thisis $LMC_HOME/sim/simulator/lib; however, you can put the physical libraryanywhere you want.112 Synopsys, Inc. October 6, 2003
