Cyclone fpga 系列 Cyclone FPGA Family ES-CYCFPGA-1.3 Errata Sheet Introduction This errata sheet provides updated information on Cyclone devices. This document addresses known issues and includes methods to work around the issues. Power-Up Altera has identified a silicon issue affecting Cyclone EP1C6 devices. The EP1C6 engineering sample (ES) and production devices can require Current up to 1.2 A of current on the VCCINT voltage supply to successfully power up. The duration of the ICCINT power-up requirement is dependent on the VCCINT voltage supply……
