It is the assurance that the user design is secure and operates as intended for the life of the product. Secure ProgrammingĬryptographic design security in Microsemi FPGAs and SoC FPGA provide information security of the configuration data. It requires SPI flash to be connected to the device with a valid bitstream. Program-recovery feature is available to allow device to automatically recover from a power failure during a programming operation. Then the device verifies the content of SPI flash and goes through the programming cycle. Or, an external SPI programmer can be used to program the SPI flash directly. In-Application Programming (IAP) – In this programming mode, device receives the bitstream from a host device and writes it into an external SPI flash. This mode allows user to choose their preferred communication interface to program device in-system. This mode requires devices to have required firmware for Cortex-M3 to implement these features. Cortex-M3 core receives the bitstream and feeds to the system controller which in-turn programs the device. In-System Programming (ISP) – This mode is supported in SmartFusion2 SoC FPGA devices and allows devices to fetch programming bitstream from communication ports like USB, UART, SPI, I2C etc. This mode is also useful in field upgrades. The system controller configures SPI master mode and other on-chip resources to enable the programming.Īuto Update – Auto-update mode allows a pre-programmed device to be automatically programmed with an updated bitstream image if image is available in external SPI flash whenever devices powers-up or comes out of hardware reset. For SPI programming, a dedicated port SPI_SC is available.Īuto Programming – In this mode, the devices are automatically programmed by downloading the bitstream from an external SPI flash memory. The system controller residing inside the device handles the programming and complies to IEEE 1532 and IEEE 1149.1 JTAG standards. Device can be programmed either using JTAG interface or SPI.

PolarFire, SmartFusion2 and IGLOO2 devices support programming via an external master as well as self-programming.

The solution comprises hardware, software, and collaterals, which allow easy access to the programming and debugging features available in SoC FPGA and FPGA devices and shorten the learning curve. Various features available on-chip and in tools allow for secure remote upgrade and protection against overbuilding.

Microsemi’s Programming solutions provide various programming options based on product’s life-cycle and system requirements.
