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.

Are you talking about travis-ci status? Or do simply mean the test completes successfully?
