License Codeword Version Compatibility

Each Keysight software release comes with a base license codeword version requirement. The base license codeword version is the minimum number that enables a release to run. Some versions of Keysight EDA software also have an upper limit of the codeword version that software release enforces. This upper limit is set for an additional two versions beyond the base version. The software cannot run if the codeword version exceeds that upper limit.

When you mix codeword versions on a license server and a user runs different versions of a product that use different base license codeword versions, extra licenses may be pulled and result in unexpected “Licensed number of users already reached for this feature” errors. To avoid this either have all your licenses updated to use the latest codeword version, if possible, or separate the licenses by codeword version and put the two sets onto separate license servers. When you mix codeword versions compatible for a given product release version with codeword versions that exceed the upper limit for that same product release version, that product release version would take a longer time to obtain a license due to the additional requests made to FlexNet server until a compatible license version is found. To avoid such a license checkout performance degradation, we strongly recommend you to separate out a compatible set of licenses from those exceeding the upper limit for a given product release version and put the two sets onto separate license servers.

For License version compatibility of older releases, see License Version Compatibility (Unsupported Releases).
