Configuration Features5. Select Add File and add a Stratix III device SOF(s).6. Select the name of the file you added to the SOF Data area and clickProperties.7. Check the Compression check box.When multiple Stratix III devices are cascaded, you can selectively enablethe compression feature for each device in the chain if you are using aserial configuration scheme. Figure 11–2 depicts a chain of two Stratix IIIdevices. The first Stratix III device has compression enabled and thereforereceives a compressed bitstream from the configuration device. Thesecond Stratix III device has the compression feature disabled andreceives uncompressed data.In a multi-device FPP configuration chain (with a MAX IIdevice/microprocessor + flash), all Stratix III devices in the chain musteither enable or disable the decompression feature. You can notselectively enable the compression feature for each device in the chainbecause of the DATA and DCLK relationship.Figure 11–2.
