Simulator Configuration Guide for Synopsys Models

Simulator Configuration GuideChapter 7: Using QuickSim II with Synopsys ModelsModel RegistrationBecause multiple descriptions can exist for the same component, you must register eachmodel to specify the model’s component interface and descriptors. The lm_model utilityis a tool for registering hardware models. If a QuickSim II component does not alreadyexist, lm_model creates one, along with a component interface that specifies thefunctional, graphical, and technology descriptions for the model.The lm_model utility registers a hardware model in three steps, using the model’s ShellSoftware as source files:1. Creates a symbol for the model and registers it with the component interface.2. Creates, compiles, and registers a technology File, which contains the timingdescription of the model in a Mentor Graphics proprietary format. The user canchoose to use either this technology file or the Shell Software timing files duringsimulation. For more information, refer to “Timing Shell Selection” on page 179.3. Registers the functional description with the component interface.The lm_model command, as illustrated in Figure 8, calls a number of other utilities. Thereg_model utility and Technology Compiler (tc) are Mentor Graphics utilities; for moreinformation about these utilities, refer to your Mentor Graphics documentation. Formore information on the tmg_to_ts converter, refer to “lm_model Command Reference”on page 185. For more information on the lm_model utility, refer to “tmg_to_tsCommand Reference” on page 188.October 6, 2003 Synopsys, Inc. 169
