VHDL Studio™ integrates design entry with fast VHDL’93 behavioral and structural (VITAL/SDF) simulation. With a single seamless environment for both design entry and verification, less time is spent learning and using two dif-applications.

VHDL Editor
The built-in editor performs color highlighting of VHDL source code to facilitate reading, and automatic identifier completion to reduce typing.

State Machine Editor
The most intuitive way to design a state machine is with a state machine diagram. VHDL Studio™ includes a graphical state machine diagram editor for intuitive state machine entry that automatically and transparently generates a VHDL implementation.

On-the-fly Error Detection
Using incremental analysis, VHDL Studio™ can instantly detect syntax errors as you type and eliminate the tedious compile, locate error, and edit cycle.

Auto-prompting
Auto prompts provide you quick information about previously defined subprogram signatures, and signal/ variable types without leaving your current editing position to locate the definition in another location or even in another file. Auto prompts are always up-to-date due to VHDL Studio’s incremental analysis engine.

Instance/Component Creators
Component and instance wizards make component declaration and instantiation a snap. Just select any entity from your project and the component creator will insert a matching component declaration in your design. The instance creator provides a simple graphical interface for assigning local signals to the ports of the instantiated entity for fast, errorfree component instantiation.

Graphical Testbench Designer
The testbench designer provides a graphical waveform editor for simple and intuitive testbench design. In interactive mode, the simulator updates output waveforms as you edit the inputs. Timing checks and data checkpoints are also easily added to the waveform diagram. You can run the testbench within VHDL studio for a graphical display of timing and data violations or run the automatically-generated VHDL testbench yourself.

Native VHDL’93 Compiler
VHDL Studio™ includes a new version of the Green Mountain VHDL Compiler for fast, direct-compile simulation.

Waveform Display
Graphical waveform display makes simulation results easy to browse and understand.

Source-level debugging provides statementbystatement execution for detailed debugging. Source-level debugging includes breakpoints to quickly simulate to the point of interest for detailed, statement-bystatement debugging.

Tcl/Tk Scripting
The simulator provides Tcl/Tk script support to enable unlimited customization and automation.

VITAL Optimization
The new version of the Green Mountain VHDL Compiler in VHDL Studio™ includes VITAL specific optimizations and built-in VITAL libraries delivering performance up to 7 times faster than the previous version.

SDF Backannotation
Post-route simulation with timing information is provided through standard SDF backannotation.

Hierarchy Browser
The hierarchy browser provides a complete structural view of your design’s units, blocks, instances and processes, as well as type, signal, variable, and subprogram information. Double clicking on any item in the browser instantly brings you to the file and line number where the item is defined. Thanks to VHDL Studio’s incremental analysis, the browser is always up-to-date with changes made in the editor.

Hypertext Navigation
In VHDL Studio™ your VHDL is more than plain text, its hypertext! If you forget the type of that signal, or the arguments to that function, simply right click on its name to instantly jump to its definition.

Navigation History
Even with all the advanced design navigation features of VHDL Studio™. you’ll never get lost with the “back” button, which will quickly return you to your previous location in the design.
