Debugging PL on Zynq

I am trying to learn to debug my designs and from my searches none of the video's speak of how to debug with a Zynq.

I used video: https://www.youtube.com/watch?v=acpIiRTxzcM

and marked a couple of signals debug and when I programmed the device I get the message there are no debug cores. Another issue is that I get messages that tell me that when I save the design after I add the debug i get a message telling me that I can avoid rerunning synthesis by marking 'Force Up-to-Date'.

Questions:

After I add debug should I rerun synthesis? I thought when I added debug via "Insertion Flow" I didn't have to rerun synthesis.

I am debugging with the complete design including the processor. Should I debug the individual pieces before I put them into the design?

Is there more information somewhere that explains how to do this with a zynq?

Hello Ray,

In general, as discussed in the video you reference, it is usually best to debug individual pieces if feasible. Normally you would only need to rerun synthesis if you instantiated the debug cores. You will need to rerun implementation with either the insertion or instantiation method.

There are a couple of good Xilinx tutorials that cover using the Vivado Analyzer:

http://www.xilinx.com/support/documentation/sw_manuals/xilinx2015_4/ug936-vivado-tutorial-programming-debugging.pdf

http://www.xilinx.com/support/documentation/sw_manuals/xilinx2016_1/ug940-vivado-tutorial-embedded-design.pdf

You should always try to use the version of the tutorial that matches the version of Vivado that you are using.

We also cover using Vivado Analyzer in the Avnet Zynq HW Speedway workshops. The latest version we have posted is Vivado 2014.4.1:

Good luck with your studies!

I have followed the SpeedWay Labs and am at Lab 8 and I can't seem to get the interrupt to work correctly. I am using Vivado 2016.1 and

#define INTC_PWM_INTERRUPT_IDt XPAR_FABRIC_PWM_W_INT_0_INTERRUPT_OUT_INTR

doesn't exist. I tried many different ways to get something that looks like this interrupt, but am basically not able to figure it out. I tried to convert the solution to the newer vivado and it didn't show up then. I created the project from scratch and it still didn't show up.

I even tried hard coding it to 61 as the post said it should be. I may have missed something in my hardware, which I am going back over.

Any suggestions?
