You can configure multiple devices with a single EPCS device. However, you cannot
cascade EPCS devices. To ensure that the programming file size of the cascaded
FPGAs does not exceed the capacity of an EPCS device, refer to Table 1 on page 1.
Figure 4 shows the AS configuration scheme with multiple FPGAs in the chain. The
first FPGA is the configuration master and its MSEL[] pins are set to AS mode. The
following FPGAs are configuration slave devices and their MSEL[] pins are set to PS
mode.
Figure 4. Multiple Devices in AS Mode (1), (5)
Notes to Figure 4:
(1) For more information about the VCC value, refer to the configuration chapter in the appropriate device handbook.
(2) EPCS devices cannot be cascaded.
(3) Connect the MSEL[] input pins to select the AS configuration mode. For more information, refer to the configuration chapter in the appropriate
device handbook.
(4) Connect the MSEL[] input pins to select the PS configuration mode. For more information, refer to the configuration chapter in the appropriate
device handbook.
(5) For more information about configuration pin I/O requirements in an AS configuration scheme for an Altera FPGA, refer to the configuration
chapter in the appropriate device handbook.
