vcdcat misses an input signal

[arunpatro]

I have in my .vcd file, a variable called tb.clk. We can see it here like this ->

from vcdvcd import VCDVCD

vcd = VCDVCD('test/rotate100/wave.vcd')
print(vcd.references_to_ids.keys())

dict_keys(['tb.stim1.clk', 'tb.tb_mismatch', 'tb.clk', 'tb.load', 'tb.ena[1:0]', 'tb.data[99:0]', 'tb.q_ref[99:0]', 'tb.q_dut[99:0]'])

But when I do vcdcat test/rotate100/wave.vcd, I get a .txt file that is like this:

0 time
1 tb.data[99:0]
2 tb.ena[1:0]
3 tb.load
4 tb.q_dut[99:0]
5 tb.q_ref[99:0]
6 tb.stim1.clk
7 tb.tb_mismatch

Why does it skip the tb.clk signal all together?

Hi, can you provide a sample vcd to reproduce?
