Press Release for Product Upgrade: May 2, 2012

VHDL/Verilog Converters upgraded for Verilog 2005

SynaptiCAD has upgraded the V2V tools that translate bidirectionally between Verilog and VHDL source code. These translators are primarily aimed at converting behavioral and/or RTL-level code and are most often used when a designer has received IP in another language than his preferred design language.

For more information on the V2V Translators see the Translation to and from VHDL & Verilog page.

The Verilog2VHDL tool now supports the following Verilog 2005 constructs: multi-dimensional arrays, signed regs and nets that convert to VHDL numeric_std.signed data types, Verilog 2005 event control expressions such as @(posedge foo, posedge bar), the new localparam keyword, module parameter port lists, and named parameter assignments.

The VHDL2Verilog tool also received several enhancements including better generation of bit ranges for parameters generated from VHDL constants and an option to translate VHDL integer literals into fixed-length bit strings for synthesized designs.

HDL Debugging Support

The V2V tools are stand-alone command-line programs, but SynaptiCAD's graphical HDL debugger, BugHunter Pro, can also be used to configure options to the translators and launch them on files in an HDL design project. Using BugHunter in combination with the V2V tools, users can quickly translate a design, then compile and simulate both the original files and the translated files to compare their output, make any necessary corrections, then resimulate. The BugHunter debugger is compatible with the following VHDL and Verilog simulators: SynaptiCAD's Verilogger Extreme, Cadence's Incisive, Synopsys VCS, Mentor Graphic's ModelSim, and Aldec's ActiveHDL.

Translation Service

SynaptiCAD will also perform translation of HDL code as service, using their translators to do the bulk of the work, then making manual corrections as necessary. SynaptiCAD particularly recommends this service for designers who are not fluent in both Verilog and VHDL coding. The cost of the translation service typically depends on the size of the IP to be translated.

Pricing and Availability

TThe V2V translation software is available on Windows and Linux. The software can be licensed on either a permanent or leased basis, and both floating and node-locked versions are available.
