Vivado Design Suite is a software suite produced by Xilinx for synthesis and analysis of hardware description language (HDL) designs, superseding Xilinx ISE with additional features for system on a chip development and high-level synthesis. Vivado represents a ground-up rewrite and re-thinking of the entire design flow (compared to ISE).

Like the later versions of ISE, Vivado includes the in-built logic simulator. Vivado also introduces high-level synthesis, with a toolchain that converts C code into programmable logic.
Replacing the 15 year old ISE with Vivado Design Suite took 1000 person-years and cost US$200 million.
