Chapter 4 - Behavioral Descriptions There are three different paradigms for describing digital components with VHDL, structural, data flow, and behavioral descriptions. This chapter dicusses the behavioral approach.
When you're creating a new design, just enter your design using your preferred mix of graphics and text. EASE supports industry standard version control environments that deal with design and configuration management, enabling multiple users to work simultaneously on one EASE project.
The browser offers two views: It also provides many status details of the different objects, like verification status, 'instantiated from' info, version number and more.
From the browser, all objects can be opened in their respective editor block diagram, state diagram, truth table or text editor.
The hierarchical view shows the hierarchy on the selected entity or configuration. It allows you to create or delete configurations. Here you can also changes the binding of an architecture to a component when having multiple architectures for an entity.
Block Diagram Editor The block diagram editor allows you to easily decompose your system into functional blocks. It is up to you how detailed you want to make the decomposition. Each block can be implemented using one of the four available editors.
Facilitating an abstraction level between block diagrams and plain HDL code, the block diagram editor allows you to graphically represent cooperating VHDL processes or Verilog always statements. The processes can be implemented using state diagrams, truth tables or HDL text. This approach visualizes the design's data flow inside a single diagram.
Any valid VHDL expression or Verilog statement can be used to define actions and transition conditions. Transitions can be synchronous or asynchronous; outputs can be clocked or combinatorial. The state diagram editor supports a variety of state assignment methods, including binary, gray, one-hot and two-hot.
User defined assignment is also supported. The generated HDL is optimized for time and area to achieve the best possible synthesized design from leading synthesis tools.
Truth Table Editor The truth table editor is useful for decoders and decision logic. The spreadsheet-like editor in combination with a flexible and smart use of column headers allows a compact visualization of the intended behavior.
A column-fill wizard is available to generate data in various encoding styles and representations. EASE will create symbols and component declarations for instantiated modules. Symbols can be easily updated to the latest version of your code.
Existing HDL can also be translated into block diagrams. Linting is an additional verification effort that identifies potential design problems like range mismatches in assignments of vectors, or read-only signals and optimizes the design by identifying unused signals and definitions.
Errors, warnings and notes are reported in the verification pane. The messages are hot-linked to the corresponding editor to quickly navigate to the offending code. The best way to work together on a project is by using a design environment that allows a group of designers to simultaneously work on the project without interfering with each other.
This fine grain control allows you to edit the parts that you need to work on while your colleagues can still read these parts. A wizard will help the user to select the appropriate tools and set the options for these tools.
Extra tool buttons will be added to the GUI for easy access to the selected tools. A list of tools supported by default is provided below. Other tools or vendors are easily added through the Tcl interface.Circuit Design with VHDL, 1st edition, Volnei A.
