THE RELEASE INCLUDES WURLDTECH ACHILLES Communications Certification Level 1 and Level 2, the industry benchmark for securing industrial connected devices. This certification protects the critical embedded infrastructure, reducing risks of cyber security threats and attacks.

Another feature, simplified mandatory access control kernel (Smack), is a Linux kernel security module that protects data and process interactions from malicious manipulation by using a set of custom mandatory access control rules. Designed for easy implementation, Smack consists of three components: a Linux security module for file systems; a startup script to ensure correct attributes for configuration; and a set of patches to the GNU core utilities package for communications.

In addition to the security features, additional industrial protocols are available in this version of the MEL product: CANopen, IEEE 1588 Precision Time Protocol (PTP), BACNet, and Industrial Internet of Things support. Expanded support for the following processors is also included: NXP TWR-LS1021A, NXP i.MX6 Sabre Series, NXP i.MX 6Solo X, Xilinx Zynq ZC702ED, and Zed Board.

The MEL platform also supports the Yocto Project 2.0 (“Jethro”), the latest version of open source comprising interoperable tools, metadata, and processes for the rapid, repeatable development of Linux-based embedded systems. Components of the Yocto 2.0 Project for this release include GCC 5.2 and toaster support. The company's Sourcery Code Bench IDE has been extended to support kernel and kernel module debug.

“For industrial automation and applications, security is crucial for embedded infrastructure, and our integrated Mentor Embedded Linux solution meets security and regulatory compliance,” stated Scot Morrison, general manager of Mentor Graphics Embedded Systems Division. “Our latest release enables embedded developers to create advanced industrial applications with minimal risk so they can develop innovative products with greater productivity.”
