Simulator Configuration Guide for Synopsys Models

Simulator Configuration GuideChapter 7: Using QuickSim II with Synopsys ModelsThe Mentor Graphics Design EnvironmentIn the post-V8.0 QuickSim-family environment, an instance of a component placed on aschematic references a component interface. A component interface contains a set ofdescriptors that define aspects of a component, such as its functionality, graphicalrepresentation (symbol), and timing constraints.There can be several variations of each descriptor for a component, such as:●●●Several functional descriptions of the component using different modeling methodssuch as BLM, VHDL, or hardware models.Several graphical descriptions (symbols) of the component such as ANSI,MG_STD, or your company standard.Several technology descriptions (timing constraints) of the component withdifferent timing grades.The Mentor Graphics analysis tools use the value of the MODEL property as a label toidentify the descriptors that define the model. For example, Figure 7 shows an instancewith a MODEL property of $lm. The $lm label is the default label for the functionaldescription of a hardware model. By examining the model table of the componentinterface, a match can be found between the MODEL property and the files thatcomprise the functional description of the hardware model.October 6, 2003 Synopsys, Inc. 167
