Simulator Configuration Guide for Synopsys Models

Simulator Configuration GuideChapter 7: Using QuickSim II with Synopsys ModelsAttentionIf you are using Shell Software that contains enhanced features—such asmodel state tracking or “when” conditions—the translation to the resultingtechnology file may be incomplete and contain “compromise” statements. Ifyou elect to use the technology file instead of the Shell Software duringsimulation, the device may exhibit incorrect timing and/or behavior. Toeliminate this possibility, translate the technology file from pre-R2.0 ShellSoftware, which does not contain these statements, or use the Shell Softwaredirectly during simulation by issuing the SIGnal INSTance lst command onthe hardware model instance. For more information about this procedure,refer to “Timing Shell Selection” on page 179.lm_model Command ReferenceThe lm_model shell command registers a hardware model by invoking hardware modelregistration and conversion programs.Syntaxlm_model input_dir [output_path] [-Dir name] [-Ifc interface] [-LAbel label][-Mdl mdl_filename] [-Step Register|Symbol|Timing|Update] [-Replace][-VERBose] [-Help] [-Usage] [-VERSion] [-Old] [-LM]Required Argumentinput_dirSpecifies the pathname to the directory containing the files tobe registered. This argument is required and must appear first.All pathname specifications use the following locationconvention:If the pathname is relative, the input_dir is assumed to be inthe working directory, as specified by $MGC_WD. If$MGC_WD is not set, the input_dir is assumed to be in thecurrent working directory.If the pathname starts with a dollar sign ($), the input_dir isassumed to be in the location of the location map variablespecified after the dollar sign.If the pathname is an absolute pathname, the input_dir isassumed to be in the location of the absolute pathname.October 6, 2003 Synopsys, Inc. 185
