Not sure if this is in the right thread for this, but it is related to a question I'm doing.
1. Homework Statement
I've been tasked with realising a logic circuit that has 3 inputs and 2 outputs which have separate Boolean equations. The circuit is based around a LS153, 1 of 4 multiplexer which needs additional logic added to make the Boolean outputs. I'm trying various decoder and gates to get the Boolean, but I thought that I'd make a start of the circuit in SIMetrix as we have to test it. I've never used it before properly but though it looked quite straightforward...however, I'm stuck on how we place the hi/low inputs to the circuit. There doesn't seem to be a nice simple switchable hi/low box that I can put onto the inputs. Does anyone have experience of testing digital circuits in SIMetrix that could talk me through how we place an appropriate line voltage and then 'switch' it hi/low to test my circuit.
