What is the actual uncompressed .rbf file size for Cyclone III LS devices?

Environment

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

The .rbf sizes for Cyclone® III LS devices published in the Cyclone III device handbook are the preliminary numbers based on estimation. The actual .rbf sizes generated beginning with the Quartus® II software version 9.1 SP2 are accurate. The final .rbf sizes will be published in the next Cyclone III device handbook update. The table below lists the approximate uncompressed configuration file sizes for Cyclone III LS devices. To calculate the amount of storage space required for multiple device configurations, add the file size of each device together.   

Device

Data Size (bits)

EP3CLS70

26,766,760

EP3CLS100

26,766,760

EP3CLS150

50,610,728

EP3CLS200

50,610,728

 

If you are using compression, the file size varies after each compilation because the compression ratio is design dependent. For more information about the decompression feature, refer to Configuration, Design Security, and Remote System Upgrades in the Cyclone III Device Family (PDF).
