Diamond Design Software from Lattice Semiconductor Enables Enhanced Security Features for MachXO3D FPGAs

Sponsored by Businesswire

Lattice Semiconductor Corporation (NASDAQ: LSCC), the low power programmable leader, today announced immediate availability of a new software release (SP1) for its powerful Lattice Diamond® 3.11 design software that includes new capabilities to access the MachXO3D™ FPGA’s security features that protect system firmware against data and design theft, product cloning and overbuilding, and tampering.

“Firmware is an increasingly popular threat vector for today’s cyberattacks and can leave companies exposed to threats against their products, profitability, and corporate reputation. OEMs are looking for easy to implement, hardware-based security solutions that help their computing, communications, industrial control and automotive systems protect, detect and recover from firmware attacks,” said Roger Do, Senior Product Line Manager, Software at Lattice. “These new features in our Diamond software enable locking and encryption in the MachXO3D that protect against unauthorized access or modification of the FPGA’s flash memory, thus preventing any functional device modification or erasure.”

The new Diamond 3.11 software release simplifies creation of the public, private, and encryption keys that confirm the authenticity and confidentiality of a MachXO3D FPGA bitstream; a requirement for implementing Root of Trust (RoT) applications. Furthermore, designers can quickly and easily build RoT algorithms that block external attacks by dynamically locking the MachXO3D’s read, program, and erase protection features. The new software release also enables protection of secure key material and system configuration and protection boundary manifests stored in the MachXO3D device’s internal flash memory.
