ModelSim’s graphic interface
While your operating system interface provides the window-management frame, 
ModelSim controls all internal-window features including menus, buttons, and 
scroll bars. The resulting simulator interface remains consistent within these 
operating systems:
• SPARCstation with OpenWindows or OSF/Motif
• IBM RISC System/6000 with OSF/Motif
• Hewlett-Packard HP 9000 Series 700 with HP VUE or OSF/Motif
• Microsoft Windows NT and Windows 95/98
Because ModelSim’s graphic interface is based on Tcl/TK, you also have the tools 
to build your own simulation environment. Easily accessible preference variables 
and configuration commandsgive you control over the use and placement of 
windows, menus, menu options and buttons. 
Standards supported
ModelSim VHDL supports the IEEE 1076-1987, 1076-1993 VHDL, 1164-1993 
Standard Multivalue Logic System for VHDL Interoperability and the 1076.2-
1996 Standard VHDL Mathematical Packages standards. Any design developed 
with ModelSim will be compatible with any other VHDL system that is compliant 
with either IEEE Standard 1076-1987 or 1076-1993.
ModelSim Verilog is based on the IEEE Std 1364-1995 Standard Hardware 
Description Language Based on the Verilog Hardware Description Language. 
(ModelSim 5.2e does not currently support VPI routines for PLI 2.0.) The Open 
Verilog International Verilog LRM version 2.0 is also applicable to a large extent. 
Both PLI (Programming Language Interface) and VCD (Value Change Dump) are 
supported for ModelSim PE and EE users.
In addition, all products support SDF 1.0 through 3.0, VITAL 2.2b, and 
VITAL’95 - IEEE 1076.4-1995. 
Assumptions
We assume that you are familiar with the use of your operating system. You 
should be familiar with the window management functions of your graphic 
interface: either OpenWindows, OSF/Motif, or Microsoft Windows NT/95/98.
