Best debugging tool for my situation?

Hello people! I have created a small project for the DE0-Nano using the block editor and some custom FiniteStateMachine VHDL code to act as a ADC interface. I am using the ADS7953 of TexasInstr...

Hey thanks a lot!

I do not need to get the measurements this way, though, since I have already created the SPI interface for the ADC. Just for my information, I have a question here: Is there any ready made SPI interface block in the standard library? I couldn't find it and I have the inkling that this is due to the fact that SPI is no formal standard.

In my setup i use the classic external 50MHz crystal of DE0-Nano and inside I elevate the clock through a PLL block to 450MHz. I hope that Cyclone IV withstands that frequency. For the sampling part the SPI clocking is done at 18.75MHz.

End point is that I just want to see that my custom made SPI interface successfully communicates with the ADC chip and gets the 16bit values to the registers.
