Introduction Higher mask cost and increasing minimum lot sizes, two economic trends of the semiconductor industry, are making FPGAs increasingly more cost effective compared to the competing ASIC solutions. A new business model enabled by the security capabilities of nonvolatile antifuse and Flash-based FPGAs will also be discussed. Data security: the designer wants to prevent the data being sent to or from the FPGA or ASIC platform from being copied, corrupted, or otherwise interfered with. Figure 1: Classes of Design Security Needs IP security is the primary concern of companies or IP developers whose competitive advantage is derived from their ability to implement the design.

FPGAs for mission-critical applications
Rajiv Jain QuickLogic - Leave a Comment Most FPGA technologies fail to address key mission-critical design requirements, but anti-fuse-based architectures succeed, providing essential attributes such as radiation resistance and design security. But for military and aerospace applications, memory-based FPGA technology is known to fall short in addressing several important requirements, including radiation resistance and design security. Anti-fuse FPGA technology successfully addresses these requirements to bring the advantages of programmable logic to mission-critical system design. Many developers understand that mission-critical systems must be designed for reliable operation in extreme environmental conditions, but find that most FPGA technologies are hard-pressed to meet these needs.
Design Security in Nonvolatile Flash and Antifuse FPGAs
In the first module we introduced programmable logic devices in the FPGA. In this module, we will extend our knowledge of FPGA capabilities so that we can choose the right one when working on a design. Designing digital devices is a creative process, much like cooking up a new recipe or painting a new picture. To be proficient, we need to know what ingredients are available to make our new creation. Xilinx, Altera, Microsemi and Lattice all make great programmable logic devices, but none of them will work for every application. Each vendor has their specialities.
