Chris,
The output signal status is the output of the module dut_test which is in the file "ifchains.v".

I can see that signal a in tb_ifchain1 changes from 0 to 12 & signal b in tb_ifchain1 changes from 0 to 2 at time 100 ns.
Just before the 100 ns. I see signal rstn in both tb_ifchain1 & dut_test go high to lo on the positive transition of the clk in both tb_ifchain1 & dut_test.
 
While the signal status in both tb_ifchain1 & dut_test is always red.
Also the signals a & b are yellow in dut_test and green in tb_ifchain.  

Should this be normal, since the signals a & b are only used in dut_test? 
I am thinking, not sure, that upper 2 bits of signal a 1100 and the 2nd bit of signal b 0010 should result in the status going to 1 in dut_test.

This would be green in the gtkwave figure.  Instead I always see a red signal.

I get the same results on the Raspberry Pi as on the PC.  On the PC I am using a different myhdl.vpi  which changes the ifchain file at runtime.

My errors now must be how I am setting the values in the file tb_ifchains.v.

Let me if I can provide any other information.
thanks in advance.

What "green light" status are you talking about?
Are you talking about travis-ci status?  Or do
simply mean the test completes successfully?

Regards,
Chris
