Advanced algorithms used today in wireless, medical, defense, and consumer applications are more sophisticated than ever before. Vivado® High-Level Synthesis included as a no cost upgrade in all Vivado HLx Editions, accelerates IP creation by enabling C, C++ and System C specifications to be directly targeted into Xilinx All Programmable devices without the need to manually create RTL. Supporting both the ISE® and Vivado design environments Vivado HLS provides system and design architects alike with a faster path to IP creation by :
Vivado HLS supports older architectures specific to ISE Design Suite and installs automatically as part of the Vivado HLx Editions
