VCD File Parser

Java VCD waveform parser API for building custom waveform analysis tools

This parser has been developed to help users to implement their own tool/utility which involves VCD file read/write or both. It reads VCD and populates its internal data structures. There are APIs to extract the populated information from the datamodel. It has been bundled as an executable JAR file along with a sample application which reads a VCD file and dumps it back to show the users that they will be able to extract every bit of VCD information from the parsed database. You need JRE 1.8 or above in order to use this parser. Please refer to the document for the detail of the available APIs.

Send your feedback to help@edautils.com for further improvement of this utility.

Trusted by design teams worldwide

The collection of tools and utilities fills a real void in EDA. The baya tool is exactly what we had been looking for to assemble large top-level modules in Verilog. The GUI and high-level TCL commands are intuitive, allowing designers to get started immediately.
Michael TrocinoIC Design Manager, Coherent Logix
Thanks for efficient tools which have been successfully used in our internal wireless design flow. Friendly support has been highly appreciated.
Claudine RaibautEDA Manager, Texas Instruments
Baya is a mature production quality tool with features and capabilities beyond those of tools provided by large EDA vendors. Its flexibility is a key reason we have chosen it for use in our Cloud-based platform.
David FritzCEO, Social Silicon
Kanai produced an excellent tool set, which is very useful for complex system-on-chip integration flows. We were skeptical in the beginning, but later got really impressed by the high quality and ease of use.
Boris V. KuznetsovCEO, SOCC
Thanks a lot for creating DesignPlayer and the huge Java class library behind it. Your strong support makes me confident to explore more details in future.
Rolf KemperManager, Mixed Signal Design, Renesas Electronics Europe
EDAUtils is one of the most comprehensive tools for SoC design and integration, and it is available for free. I included EDAUtils in the OpenTech Package as a featured application.

The VHDL2Verilog translator worked great, even handling the generate statements in the source VHDL. It met our needs exactly.
Jerry FrenkilVP of Engineering, NanoWatt Design
We use the Verilog Parser for developing FPGA CAD applications. The library is very stable and EDAUtils provided much helpful support to us.
Dustin PetersonUniversity of Tübingen
I like the IP-XACT tools and others that you have developed. The IP-XACT tools are great.
Amal KhailtashLead FPGA Designer, Ciena Communications
The netlist parser provides an easy to use and flexible environment for developing my own custom analysis tools. The best part has been the prompt and helpful support.
Gene Y. WuUniversity of Texas
We have been using the Verilog testbench generator in Unix. It is really useful in the coding process and easy to use. I would recommend their tools.
Lucas TeixeiraSMDH
That really helped me now. I got the job done at the right time.
