Chipscope - Is it possible to probe a bidirectional signal using Chipscope?

Description

Keywords: IOBUF, Chipscope, probe, bidirectional, bi-directional

Is it possible to probe a bidirectional signal using Chipscope?

Solution

No, it is not possible to probe a bidirectional signal inside the I/O buffer as there is no route for this signal back into fabric. To work around this, you can probe the Input, Output and the tristate enable of your I/O Buffer.
