Problem after adding Microblaze to the design

Hi,

I am fairly new to developing projects using FPGAs especially using Vivado tools. I am working on developing a graphics application on Arty S7 development board which has the Spartan7 FPGA. When I create the project just using VHDL, I am able to see the graphics output on screen. But when I create an IP core for the project and add Microblaze to it using IP Integrator, and export the hardware to SDK to program it, I am not able to see the right output on screen. I can just see a black screen, so not sure where I am going wrong. I was wondering if it has anything to do with clocking or timing. Again I am really sorry if the question seems basic, but do we have to add separate timing constraints file for the project? Because when I did the same project using Xilinx ISE, there was no need for manual timing constraints.

Thank you so much in advance for your time and help.

Re: Problem after adding Microblaze to the design

Spamming an un-answered post to multiple forums isn't going to make the post any better.

Please see:

But just to be a nice guy, let me ask:

What's the Microblaze got to do with it? Are you saying you can successfully package your design as an IP, instantiate it in an IP Integrator block diagram, and produce a working bitfile--but then if you simply add a Microblaze to your block diagram, the original IP stops working? Or did you not try that step yet?

Re: Problem after adding Microblaze to the design

Hi Joe,

I am really sorry if it came off as spamming, I am new to posting in forums and was not aware of the best procedure to go about. The reason I posted this query in multiple forums is because I was not able to figure out what was causing the issue or how to debug it, and hoped the right forum can identify any mistake I was making or any advice on how I could debug it. If I knew what the issue was I would have posted it only in the respective forum.

To clear the confusion, I have successfully packaged the design as an IP, instantiated it in an IP integrator block diagram along with Microblaze, and generated a bit file as well. And when I program the hardware through SDK and run the C program, I am not able to see the results. 

Thank you,
Tejna
