stdio.h error

[GProtoZeroW]

Xilinx newbie, but I ran source build_all.tcl and ended up with

Xilinx/Vivado_HLS/2016.1/include/etc/ap_int_sim.h:75:10: fatal error: 'stdio.h' file not found
#include <stdio.h>
         ^

Is this just a C HDL thing.

Also in a new overlay build instance once I add the IP I have wrapped my HDL(verilog, ect.) code in to block design can I just throw down a ZYNQ IP block without making any modifications to the ZYNQ IP. And this is assuming that in the vivado project setup I specified the PYNQ-Z1 board files and added the PYNQ-Z1 constraint file.

This appears to be a problem with the Vivado environment which I've not seen before. Are you able to open Vivado HLS and create a design manually?

[GProtoZeroW]

Is HLS free, I use myHDL (python library) for my HDL (verilog) generation and then try to play the IP wrapper and block diagram games. Can you send me what TCL commands I need to have my Vivido project sent to you where I am doing the same workflow as the tutorial notebook Because I have had issues with generating the bitstream. Thanks ahead of time for working on some tutorials for the fabric. Any work on lowering the learning curve/barrier to FPGA design work for the PYNQ are going to make it a game changer

[PeterOgden]

HLS is included in the Webpack editions of Vivado so you should have access to it. What error are you getting when building the bitstream?

[GProtoZeroW]

Finaily Got some time to get back to this Started new HLS project , added the adder to project and specfied it as top cpp file I run the sythn and ~Xilinx/Vivado_HLS/2016.1/include/ap_int.h:74

#include <stdio.h>

Could you just extract a Verilog file from HLs synth

[GProtoZeroW]

Nevermind got it working. I am going to say three things:

1. if this helps me thank you
2. Always check an export like this on another machine
3. Over-abstraction is a bad thing. It's like math that doesn't show you have to calculate a number
