Data CompressionWhen you enable compression, the Quartus II software generatesconfiguration files with compressed configuration data. Thiscompression reduces the storage requirements in the configurationdevice or flash, and decreases the time needed to transmit the bit streamto the Cyclone FPGA.There are two methods to enable compression for Cyclone bitstreams:before design compilation (in the Compiler Settings menu) and afterdesign compilation (in the Convert Programming Files window).To enable compression in the project's compiler settings, select Deviceunder the Assignments menu to bring up the settings window. Afterselecting your Cyclone device open the Device & Pin Options window,and in the General settings tab enable the check box for Generatecompressed bitstreams (as shown in Figure 13–2).13–4 Altera CorporationCyclone Device Handbook, Volume 1 January 2007
