Notes

  • MISRA C is a set of guidelines developed by a non-profit organization, the Motor Industry Software Reliability Association (MISRA), regarding the reliability of software in the C programming language, particularly that for use in the automotive industry. More than 100 rules are set as guidelines regarding code in the C language. These rules are called MISRA C rules.
  • "MISRA" and the triangle logo are registered trademarks of HORIBA MIRA Ltd, held on behalf of the MISRA Consortium.

Permanent License and Annual License

Permanent license

  • No limit applies to the period of use for permanent licenses.
  • A permanent license is made effective by registering the license key that accompanies the compiler product.

Annual license

  • An annual license is valid for one year. The valid period is one year from initial registration with the Renesas Web site of the license acquisition code which accompanies the compiler product.
  • This license becomes valid after a license key is acquired by registering the license acquisition code with the Renesas Web site. (Note1)
  • The price of an annual license is lower than that of a permanent license.

Notes

  1. To acquire the license key which is required to use a compiler product, select [Obtaining a Subscription License Key] from the menu shown after logging-in to MyRenesas and register the license acquisition code which is included with the compiler product.

Difference between Permanent License and Annual License

Node-Locked License and Floating License

Node-Locked License

  • These licenses allow you to use a compiler on one specific PC per license.

Floating License

  • The licenses for the software are managed on a server, and are available for use on the PCs connected to a network within the range of the number of licenses.
  • A license is available while a PC is connected with the server on the network.
  • To use the license while disconnected from the network that includes the license server, customers can hold the license for a fixed period (as a number of days up to 99). Once the period which has been specified with the client elapses, the held license expires.
  • The license resides on a client PC for 30 minutes after it is obtained at the start of building. If building has not finished after the 30 minutes have elapsed, the client PC retains the license for another 30 minutes. This cycle is repeated until building is finished.

Upgrade (edition) License

If you have a node-locked license for a standard edition, you can upgrade from the standard edition to a professional edition by additionally registering an Upgrade (edition) License.

It does not apply to floating licenses and annual licenses.

Note

  1. Note that this form of upgrade (of the edition) is only for node-locked licenses.

Map of Upgrade (edition) License

Upgrade (version) License

The compiler licenses differ with the version. For example, V1.**.** and V2.**.** have different licenses since they are different versions.

In case of a license for an old version, you can use a new version of the compiler at low cost by additionally registering a Upgrade (version) License.

These licenses allow you to use both the new and old versions of a compiler.

This form of upgrade does not apply to annual licenses.

Each of these products is structured as the compiler alone. Separate installation of an IDE is required. Refer to this page if you wish to use the e² studio. Latest version of the e² studio >>

Compiler packages with an IDE

Each of these products is structured as the CS+ IDE that includes a compiler. If the bundled version of CS+ is not the latest version, update it. Latest version of CS+ >>

No statement regarding an IDE

In the case of annual and upgrade (between versions and editions) licenses, the products are structured as only a license key and a license acquisition code.
