[SOLVED] Missing source when conecting bus line to mux

[Hugo17]

When I connect "MyMux2" with a bus-line to the ADCdriver input (see picture) I get error messages like:

"Error (12009): Node "Misc:b2v_inst|data_mymux2_2x1" is missing source".

I share the same bus line coming from MyMux1 but here I do not get an error.

Does someone know how to solve this problem?




Thanks!

Hi,

The source of the bus is numbered with 1 to 3...and 4 to 10.
But at the destination it is numbered 0 to 10.

So number 0 at the source is missing.
Define number 0.

Hello
I think I found the problem. I mismatched inputs with outputs. This means that MyMux has inputs while I was trying to connect those signals with the INPUT signal islv_adc_data.


Now I changed the PMOD_J4 and PMOD_J5 to bidirectional signals. Unfortunately I get this error message when compiling:

Error (13076): The pin "PMOD_J4[1]" has multiple drivers due to the non-tri-state driver "clk"

PMOD_J4[1] is connected to the signal osl_adc_clk which is an output. How can I avoid this problem?

Thanks in advance
