simulation - YOSYS simulating a combinatorial circuit with a specific input

Question

I have a very simple combinatorial circuit written in .blif, such as:

.model circuit
.inputs a b
.outputs c
.names a b c
11 1
.end

Now I'd like to simulate it with yosys, and I'd like to specify the input. Basically, I am trying to replicate the simulating command from SIS, which would be "simulate 0 1" and would give as a result "Output: 0". However, it seems from the documentation that I can only simulate cirucits with clock modules. Is there a way to specify that I only want the combinatorial behaviour of the circuit?

Answer 1

You can use eval:

eval -set a 0 -set b 1

or if you want the full truth table:

eval -table a,b
