![]() ![]() Use “set -recursion_iteration_limit XX” to iterate more.Īnd then probably you would have googled it and found the following link.Īs a novice I felt bit hard on the implementation of what have been given in the above link. Have you ever tried a recursive function (having a considerable depth) ? Then you would have noticed following error message (as i myself encountered).įunction ‘’ has iterated 64 times. One useful place related to recursion can be found in the following link. But for hardware designs with tree structure it is better to have recursion in the design. But one thing that a real hardware programmer must keep in mind is hardware programming is more concerned on parallel execution rather than being sequential as in typical programming languages. Of course Verilog ’95 did not support recursion but later Verilog 2001 introduced Recursion to be generated in designs. There was a misconception that hardware design is incapable of implementing recursion functions. To have an overview on XST® synthesis please refer the following link. ![]() XST(Xilinx®) is the tool used in ISE® software to synthesize VHDL, Verilog or mixed languages and to create Xilinx® specific netlist files known as NGC files. ![]()
