Vivado® Design Suite delivers a SoC-strength, IP-centric and system-centric, next generation development environment that has been built from the ground up to address the productivity bottlenecks in system-level integration and implementation. 

It comes in two editions, Standard Edition or Enterprise Edition. Standard edition is free and is usually suitable for most student projects. Enterprise Edition includes the same software tools as the standard edition and has support for all AMD devices, including the latest device families and the largest parts in those families.
