Hi there,

I'm working with DAC on the daughter board THDB-ADA. The pin assignments are correct, I believe, but the circuit doesn't seem to be working.

Here are my waveforms from ModelSim, can somebody give me some suggestion on what I did wrong?

fyi: I create the data output to the board from 0-16300-0... (so that it will be a triangle waveform)

I'm still doing and glad to here from you.

Thank you,

Tan

I am sorry , i am very very new to DE2-115 , now i need to connect my DE2-115 to THDB-ADA_HSMC , same like yours . But can i know is there any extra coding needed in order to make the connection ? And also how do you assign the pin assignment for this ADA?
