Honored ContributorViewing Data in Bus Lines without I/O Pins in Waveform Editor [Newbie].
Hello everyone.
I am still new in Quartus II and I'm trying to design a fully parallel 8-point radix-2 fft processor. I've already done some simulation with the university waveform editor to see the data from input and output pins but I can't find a way to view the data from the inner bus lines connecting the different adders to multipliers (megacore instances). I know that one way is to attach output pins to the bus/single lines but it is too repetitive and I have to use the assignment editor to assign the pins. Can someone help me? :cool:6 Replies
Altera_ForumHave you already tried with signaltap?

You can use SignalTap to view signals inside your FPGA.
Search on Altera's site for 'signaltap' or see the following tutorial: signaltap tutorial (ftp://ftp.altera.com/up/pub/altera_material/10.1/tutorials/verilog/signaltap.pdf) Regards, Alex - Altera_Forum--- Quote Start --- You can use SignalTap to view signals inside your FPGA.

I only need to see the data in my bus lines in simulation after compiling.

If you just want to simulate your code you can use ModelSim. You can download Altera's free version from their website. This allows you to simulate your code without programming it into an FPGA. There's no need to compile anything with Quartus for this.

Thanks you for the advice. I will definitely try it.

The possibility to add and monitor inner nodes would definitely help debugging a lot! Moreover, adding inner nodes without being able to see the data in the waveform viewer is misleading and wastes time for a lot of users! Why is it possible to add inner nodes in the first place?
