This chapter describes the configuration and remote system upgrades in Cyclone
devices. Cyclone IV (Cyclone IV GX and Cyclone IV E) devices use SRAM cells to
store configuration data. You must download the configuration data to Cyclone IV
devices each time the device powers up because SRAM memory is volatile.
Cyclone IV devices are configured using one of the following configuration schemes:
■

■
■
■
Cyclone IV devices offer the following configuration features:

System designers face difficult challenges, such as shortened design cycles, evolving
standards, and system deployments in remote locations. Cyclone IV devices help
overcome these challenges with inherent re-programmability and dedicated circuitry
to perform remote system upgrades. Remote system upgrades help deliver feature
enhancements and bug fixes without costly recalls, reduced time-to-market, and
extended product life.
This section describes Cyclone IV device configuration and includes the following
