Tandem configuration is a staged configuration that brings up the PCIe protocol less than 100 ms after power to Versal adaptive SoC is stable. This is achieved using a stage 1 programmable device image (PDI). The rest of the device, including the PL, can be downloaded by the user application as a stage 2 PDI. In Versal adaptive SoC, Tandem configuration is accomplished using the CPM integrated block. Tandem configuration supports the Tandem PCIe and Tandem PROM modes. For more information, see the Versal Adaptive SoC CPM DMA and Bridge Mode for PCI Express Product Guide (PG347).
