Chapter 7: Using QuickSim II with Synopsys ModelsSimulator Configuration GuideNoteBecause the block diagram of this part does not denote specific names forthe elements, their names reflect the output pin numbers on the DIP symbol(for example, pin 23 maps to Q23).For example, to program the first six elements listed in Table 18 as counters and registerthe last four elements as data pins from an I/O port, you would use the followingcommands:ADD BUS CNTR I$230/Q23, I$230/Q22, I$230/Q21, I$230/Q20, I$230/Q19,I$230/Q18ADD BUS DATA I$230/Q17, I$230/Q16, I$230/Q15, I$230/Q14ADD LISTS CNTR DATA -C -HEXChanging Program Flow by Setting ValuesYou can use the SmartModel Windows feature to shorten large repetitive loops. Forexample, if a DMA controller has initiated a DMA transfer of 1,024 words to mainmemory, you can view the transfer of the first couple of words before stopping thesimulation. By artificially setting the value of the DMA's transfer control register, youcan control which part of the transfer to view. You can then view the last few words asthey are transferred without having to wait for the entire process.Be careful when inserting values into window elements, especially when forcing datainto program counters and instruction registers. This SmartModel Windows feature isrecommended only for users who completely understand the implications of what isbeing inserted into an element.When forcing a value onto an element, the FORCE command is always interpreted as ifthe -CHARGED switch were present. This means that the forced value vanishes whenanother event attempts to update the window element. It is not possible to FIX or WIREa forced value on a window element.Custom SymbolsSynopsys provides symbols representing default package pinouts for SmartModels.However, you may need to create custom symbols for some of the following reasons:●●To conform to internal drafting requirementsTo make a symbol match a component's pinout●To match external drafting specifications (for example, military specifications)144 Synopsys, Inc.

Simulator Configuration GuideChapter 7: Using QuickSim II with Synopsys ModelsUsers who choose to create custom symbols as an alternative to using the symbolsprovided can:●Modify a SmartModel Symbol. Start with the SmartModel symbol and modify itto match your drafting requirements. The value of the user PIN property can now bechanged without corrupting the value of the compiled PIN property.● Create a New Symbol. Create the symbol with your pin values, figure out thecorresponding pin names used by the model, and change the user pin values to thosenames.To create custom symbols, follow these steps:1. Provide required SWIFT properties on the symbol.2. Register the component.3. Map pin names to standard SWIFT pin names.SWIFT PropertiesThe following symbol properties are required to interface with a SWIFT model:● model● TimingVersion●●●pinpintypeswift_templateRefer to Table 13 and Table 14 for information about other required symbol properties.Component RegistrationWhen creating new symbols, you must add the SWIFT model to the componentinterface by “registering” the model with a type of “SWIFT”.For example, suppose you have created a new component called “my_ttl00” and youwant to use the SmartModel Library “ttl00” binary as the simulation model. You wouldregister the ttl00 model as follows:reg_model $MY_DIR/my_comp_lib/my_ttl00 -type SWIFT -label 'my_label'October 6, 2003 Synopsys, Inc. 145
