9 / 78 page 40MX and 42MX Automotive FPGA Families v3.1 1-5 I/O Modules The I/O modules provide the interface between the device pins and the logic array. Figure 1-9 is a block diagram of the 42MX I/O module. A variety of user functions, determined by a library macro selection, can be implemented in the module. (Refer to the Antifuse Macro Library Guide for more information.) All 42MX I/O modules contain tristate buffers, with input and output latches that can be configured for input, output, or bidirectional operation. 42MX devices contain flexible I/O structures, where each output pin has a dedicated output-enable control (Figure 1-9). The I/O module can be used to latch input or output data, or both, providing fast setup time. In addition, the Actel Designer software tools can build a D- type flip-flop using a C-module combined with an I/O module to register input and output signals. Refer to the Antifuse Macro Library Guide for more details. Actel's Designer software development tools provide a design library of I/O macro functions that can implement all I/O configurations supported by the MX FPGAs. Other Architectural Features User Security The Actel FuseLock provides robust security against design theft. Special security fuses are hidden in the fabric of the device and prevent unauthorized users from accessing the programming and/or probe interfaces. It is virtually impossible to identify or bypass these fuses without damaging the device, making Actel antifuse FPGAs immune to both invasive and noninvasive attacks. Special security fuses in 40MX devices include the Probe Fuse and Program Fuse. The former disables the probing circuitry while the latter prohibits further programming of all fuses, including the Probe Fuse. In 42MX devices, there is the Security Fuse which, when programmed, both disables the probing circuitry and prohibits further programming of the device. Look for this symbol to ensure your valuable IP is secure. For more information, refer to Actel's Implementation of Security in Actel Antifuse FPGAs application note. Programming Device programming is supported through the Silicon Sculptor series of programmers. Silicon Sculptor II is a compact, robust, single-site and multi-site device programmer for the PC. With standalone software, Silicon Sculptor II is designed to allow concurrent programming of multiple units from the same PC. Silicon Sculptor II programs devices independently to achieve the fastest programming times possible. After being programmed, each fuse is verified to insure that it has been programmed correctly. Furthermore, at the end of programming, there are integrity tests that are run to ensure no extra fuses have been programmed. Not only does it test fuses (both programmed and nonprogrammed), Silicon Sculptor II also allows self-test to verify its own hardware extensively. The procedure for programming an MX device using Silicon Sculptor II is as follows: 1. Load the .AFM file 2. Select the device to be programmed 3. Begin programming When the design is ready to go to production, Actel offers device volume-programming services either through distribution partners or via In-House Programming from the factory. For more details on programming MX devices, please refer to the Programming Antifuse Devices and the Silicon Sculptor II user's guides.
