HDL Designer

Visualizing Complex RTL Designs

HDL Designer combines deep analysis capabilities, advanced creation editors, and complete project and flow management, to deliver a powerful HDL design environment that increases the productivity of individual engineers and teams (local or remote) and enables a repeatable and predictable design process.


HDL Designer assists engineers in analyzing, assessing, and visualizing complex RTL designs, providing code integrity analysis, connectivity completeness analysis, HDL code quality assessment, and design visualization.


Hand-in-hand with code analysis is code creation. HDL Designer provides engineers with a suite of advanced design editors to facilitate development: interface-based design spreadsheet editor (IBD) and block diagram, state-machine, truth table, flow chart and algorithmic state-machine editors. To complement these editors, HDL Designer includes an EMACS/vi-compatible, HDL-aware text editor.


In conjunction with design analysis and creation, design management is the third important task facing designers. Along with managing the design data, teams need to manage the project throughout the design flow. HDL Designer tackles the design management problem by providing the designer with interfaces to other design tools within the flow; data and version management solutions. HDL Designer also enables easy design and complete project documentation via HTML, OLE, print, and graphics export.
