Download the free TX-LINE Calculator.

Open-Source Code

Cadence is using the Squeak open-source Smalltalk platform for research and development work. In order to comply with the Squeak license, Cadence makes modifications and enhancements to the Squeak kernel (existing classes and VM) available as open-source packages. These packages may be downloaded under the terms of the Squeak license. Download the Squeak packages.

Cadence cdsLib Plugin

The cdsLib plugin provides OpenAccess-based applications the ability to read and interpret Cadence cds.lib files. It is an alternative to the default oaLibDef plugin provided by OA to read lib.defs files. Download the Cadence cdsLib plugin.

Cadence Virtual Machine License Server

Cadence supports running license servers on virtual machines (VM), locally, or in the cloud. In order to run a license on a VM, customers must sign the letter of agreement corresponding to their environment. Please work with your account manager to sign this agreement.

Once the letter of agreement is signed, download the license utility file below and run the contained executables on the VM to collect the machine fingerprint data needed to use a VM as a Cadence license server. Windows License Utility Linux License Utility

NOTE:  Cadence supports only server VMs such as VMware ESX, Citrix XEN, etc. for local deployments. For cloud deployments, Cadence supports Amazon EC2 or Google Compute Engine.

Desktop VMs such as Virtual Box, Parallels, VMware desktop, etc. are not supported. ​

oaScan Application

oaScan is an unlicensed application that scans the contents of a library and checks for inconsistencies in the OpenAccess design, tech, and DMData databases. Optionally, oaScan can repair the inconsistencies and save the databases. Inconsistencies are more common with older versions of OpenAccess. The oaScan application is used to upgrade such data to current quality standards. Access the oaScan packages.
