Frequently Asked Questions

Q: When I attempt to download VTRAN® I also get VCAP®, VGEN® and DFTView®. Where can I download just the package I'm interested in ?

A: VTRAN®, DFTView® and VCAP® and VGEN® are shipped in a single unified bundle.  The latest release is the Source III V10.4 Software Bundle.  Software installation and upgrades are now managed with a single installer, which helps to eliminate potential version conflicts between various installs of each individual package. The software is also much more tightly integrated and also provides a convenient way for evaluating updated versions of all four products.

In addition, if you already have counted floating (or server-managed node-locked) licenses, you also now have immediate fully-licensed access to DFTView®.

Q: What is the most current release of the Source III Software Bundle, and applications does it contain?

A: The current version is 10.4.2, released Oct 6th, 2017.

The constituent applications are:

  • VTRAN® and the VTRAN® User Interface (VUI)
  • VCAP®
  • VGEN®
  • DFTView®

Q: After setting-up my VTRAN® environment as described in the README.vtran file, when I try to run the VTRAN® program I get the following message:

sh: sysdef: not found
Unable to write to temp file. Check write access.

What causes this and how can I fix it ?

A: When VTRAN® begins running it uses a system utility named "sysdef" to access some platform information. The error message is generated when it cannot find this utility. The "sysdef" utility is normally located in the /usr/sbin or the /etc directory. Check to see where it is located, then add the directory to your search path.

Q: What types of licenses are available for VTRAN®, VGEN® and VCAP®? Is there a floating license available?

A: Source III products are available under floating licenses. The license options include the following:

Node-Locked License - Allows the software to run on a single node. The software can be run multiple times simultaneously on the licensed node and can also be run remotely (using rlogin or rsh). The license is locked to the hostid of the node.

Floating/Site License - This license allows the software to run on any node that is physically connected to the licensed subnetwork at a given site. The license key for this is tied to the IP Address and hostid of a license server on the network.

User-Locked License - This license allows the software to be restricted to specific users (designated by the customer) on any node that is physically connected to the licensed subnetwork at a given site.

Q: What type of support does Source III provide with its products?

A: Source III offers support to customers purchasing any of its products through a maintenance and technical support contract. All products come with 12 months of maintenance and technical support as part of the purchase price. After the first year, maintenance and technical support can be renewed annually for 20% of the purchase price. Under a maintenance and technical support contract, customers get "hotline" telephone and internet (via email) support and automatic updates for new software releases. Delivery of all software and documentation is via our web (or ftp) site.

Q: How can I get an evaluation copy of one of Source III's products along with an evaluation license?

A: The first step is to download the desired product from our web site (www.sourceIII.com) - go the Download page and click on the appropriate link for your platform. Next use the UNIX utility "gunzip" to restore the tar file. Note that for some browsers the file will be gunzip'ed during download, but the 'gz suffix is still present. Next, create a directory to contain the software, move the tar file into this directory, and use "tar xvfp" to extract the files. Finally, follow the instructions in the README.xxx file (e.g. README.vtran) to setup your environment and search paths. You are now ready to run the program. If you would like to get a full evaluation license to run the software, from the Download Page, click on the "Request Evaluation Key" button. The hostid can be found using the following VTRAN® command option:

vtran -hostid

Q: How are the VTRAN® options licensed?

A: With a standard VTRAN® engine license, the VTRAN® program will perform vector translations between popular logic simulation formats including Verilog VCD, EVCD, WGL, STIL, Mentor, Quickturn, Synopsys VCS, TSTL2, TDL_91, and both Verilog and VHDL testbenches, and many more. In addition, specific tester interfaces can be optionally accessed. Those specific interfaces which are enabled to run are encoded in each VTRAN® license key.
