Chapter 7: Using QuickSim II with Synopsys ModelsSimulator Configuration GuideOptional Argumentsoutput_path-Dir name-Ifc interface-LAbel labelSpecifies the pathname to the directory that contains thecomponent information. If an output_path is not specified,then it defaults to the parent directory of the input_dir.Specifies just the new name of the output component directorywithin the output_path; for example, MC68020. By default,the name is created from the base name of input_dir byremoving any leading dollar ($) characters and converting alllowercase characters to uppercase. If the output componentdirectory name is the same as the input directory name,lm_model will generate an error and fail rather than overwritethe input directory.Specifies the component interface(s) with which to register themodel. Multiple component interfaces can be specified. Bydefault, the model is registered with all component interfaces.Specifies the label(s) to register with the component interface.Multiple labels can be specified. By default, the model isregistered with the $lm label, which corresponds to thefunctional description.-Mdl mdl_filename Specifies a particular model (.MDL) file within the input_dir.By default, the system uses the model file with the same basename as the output component directory, which is defined bythe -Dir switch.-Step Register|Symbol|Timing|Update-ReplaceSelects particular registration step(s):- Step Register registers the model’s functional description.- Step Symbol creates and registers the symbol.- Step Timing creates, compiles, and registers the technologyfile.- Step Update is equivalent to -Step Register and -StepTiming.By default, lm_model performs all the registration steps.Deletes the existing component directory and then recreates it.If you try to overwrite an existing symbol without using thisswitch, lm_model fails and generates an error message.186 Synopsys, Inc.

Simulator Configuration GuideChapter 7: Using QuickSim II with Synopsys Models-VERBose-Help-Usage-VERSion-Old-LMPrints additional messages while lm_model is executing.Prints help information on each of the available options, thenimmediately exits.Expands the command line and displays each argument andswitch. After printing the usage message, lm_modelimmediately exits.Prints the single-line version message, then immediately exits.Registers the model using the pre-V8.3 method, forcompatibility purposes.Does not affect lm_model execution. The system accepts thisargument for compatibility purposes.ExamplesThe lm_model utility provides several ways of specifying input and output files anddirectories. The following examples list a given input directory (model file) and desiredoutput component directory, and then show the lm_model command line you would useto get this result.Example 1Input directory: /user/models/74ls74 ($MGC_WD is set to /user/models)Model file: 74LS74.MDL (same as the component name)Component (output) directory: /user/models/74LS74 (default output path anddirectory)Command: lm_model 74ls74Example 2Input directory: /user/models/74ls74 ($MGC_WD is set to a directory other than/user/models)Model file: 74LS74A.MDL (different from the component name)Component (output) directory: /user/models/74LS74 (default output path anddirectory)Command: lm_model /user/models/74ls74 -m 74LS74AExample 3Input directory: /user/models/74ls74 ($MGC_WD is set to /user/models)Model file: 74LS74.MDL (same as the component name)October 6, 2003 Synopsys, Inc. 187
