The AMD device isolation design flow (IDF) is a design methodology that allows for information assurance, functional safety implementations, or any other application module requiring both physical and logical isolation. This methodology is backed by significant schematic analysis and software verification, namely, AMD Vivado™ Isolation Verifier (VIV), that ensures elimination of single points of failure. Single Chip Crypto (SCC) is one specific application of IDF allowing the implementation of a multichip cryptography system, in a single FPGA or a SoC.
Dynamic Function eXchange (DFX) allows for the reconfiguration of modules within an active design. This flow requires the implementation of multiple configurations, which ultimately results in full bitstreams for the first configuration, and partial bitstreams for each reconfigurable module (RM). The number of configurations required varies by the number of modules that need to be implemented. However, all configurations use the same top-level, or static, placement and routing results. These static results are exported from the initial configuration, and imported by all subsequent configurations, using checkpoints.
AMD supports the combined flow of Isolation Design Flow (IDF) and Dynamic Function eXchange (DFX) from Vivado 2020.2 onwards. From Vivado 2021.1 onwards, block design container (BDC) flow shall be used to create an IDF+DFX design. Refer to Chapter 5 in UltraFast Design Methodology Guide for FPGAs and SoCs (UG949) for more information about BDC.
