Does it require a paid license to run OpenCL on DE10 Nano developemnt board ?

Hi Hrishikesh Kale, Good day. 1) FPGAs were traditionally programmed using hardware description languages (HDL) that are synthesizable, such as Verilog and VHDL. These languages include complex constructs for describing parallel simulations and timing delays that requires specialized skills. Recent improvements in tool flows have enabled development of OpenCL heterogeneous parallel programing framework for Intel FPGAs. The OpenCL standard naturally matches the highly parallel nature of FPGAs. OpenCL allows the programmer to explicitly specify and control the thread-level parallelism, while developing in C-like programming language. This enables good match for FPGA development as it offers very high level of parallelism.
