16 / 37 page ![]() I/O Structures in IGLOOe and ProASIC3E Devices 16 v1.4 Table 9 • Hot-Swap Level 1 Description Cold-swap Power Applied to Device No Bus State – Card Ground Connection – Device Circuitry Connected to Bus Pins – Example Application System and card with Actel FPGA chip are powered down, and the card is plugged into the system. Then the power supplies are turned on for the system but not for the FPGA on the card. Compliance of IGLOO and ProASIC3 Devices 30 k gate devices: Compliant Other IGLOO/ProASIC3 devices: Compliant if bus switch used to isolate FPGA I/Os from rest of system IGLOOe/ProASIC3E devices: Compliant I/Os can, but do not have to be set to hot-insertion mode. Table 10 • Hot-Swap Level 2 Description Hot-swap while reset Power Applied to Device Yes Bus State Held in reset state Card Ground Connection Reset must be maintained for 1 ms before, during, and after insertion/removal. Device Circuitry Connected to Bus Pins – Example Application In the PCI hot-plug specification, reset control circuitry isolates the card busses until the card supplies are at their nominal operating levels and stable. Compliance of IGLOO and ProASIC3 Devices 30 k gate devices, all IGLOOe/ProASIC3E devices: Compliant I/Os can but do not have to be set to hot-insertion mode. Other IGLOO/ProASIC3 devices: Compliant |
