Configuring Stratix & Stratix GX Devicesdifferent number of padding bits during programming. However, for anyspecific version of the Quartus II software, any design targeted for thesame device has the same configuration file size.AlteraConfigurationDevicesfThe Altera enhanced configuration devices (EPC16, EPC8, and EPC4devices) support a single-device configuration solution for high-densityFPGAs and can be used in the FPP and PS configuration schemes. Theyare ISP-capable through its JTAG interface. The enhanced configurationdevices are divided into two major blocks, the controller and the flashmemory.For information on enhanced configuration devices, see the EnhancedConfiguration Devices (EPC4, EPC8 & EPC16) Data Sheet and the UsingAltera Enhanced Configuration Devices chapter in the ConfigurationHandbook.The EPC2 and EPC1 configuration devices provide configuration supportfor the PS configuration scheme. The EPC2 device is ISP-capable throughits JTAG interface. The EPC2 and EPC1 can be cascaded to hold largeconfiguration files.fFor more information on EPC2, EPC1, and EPC1441 configurationdevices, see the Configuration Devices for SRAM-Based LUT Devices DataSheet.ConfigurationSchemesThis section describes how to configure Stratix and Stratix GX deviceswith the following configuration schemes:■■■■■■■PS Configuration with Configuration DevicesPS Configuration with a Download CablePS Configuration with a MicroprocessorFPP ConfigurationPPA ConfigurationJTAG Programming & ConfigurationJTAG Programming & Configuration of Multiple DevicesPS ConfigurationPS configuration of Stratix and Stratix GX devices can be performed usingan intelligent host, such as a MAX ® device, microprocessor with flashmemory, an Altera configuration device, or a download cable. In the PSscheme, an external host (MAX device, embedded processor,configuration device, or host PC) controls configuration. Configurationdata is clocked into the target Stratix devices via the DATA0 pin at eachrising edge of DCLK.Altera Corporation 11–7July 2005 Stratix Device Handbook, Volume 2
