While i generate Verilog from c code in vivado HLS i found few input and output generated by default(i.e ap_clk,ap_rst,ap_done etc.). While i serch about it i read that software generated by default.
So my question is that Can i disable that in vivado HLS? so vivado HLS can not generate those input output by default in verilog file.
second question is that if i can not disable that by default input output so can i use ap_clk(a hardwear clock) in my c language code because i want to do work on negative edge of clock(ap_clock) in my c language code.

thank you so much for reply fanat9
i used ap_ctrl_none mode and in simple programs like a single function program in which i made led on and of according to switch and i got sucess to disable by default generated ports.
But when i make a tricky program in which i call a function inside a function(module instance into top module according to verilog) then i got error with ap_ctrl_none, without that directive mode my programs run sucessfully.
i atteched my code and error message screenshot into attachments.
kindly please solve my problem.
Thank you in advance.

looks to me that your design needs the interface because you return a value (in the main function) ...
I have difficulties to imagine a disgn with no interfaces ... self generating input and waste output ?
