If you need a "wire" instead of a simple connection between two nodes, first you have to ask "why" ??
That means you have to ask which properties of the wire you are interested in.
And the answer mainly depends on the operating frequency range.
(Resistance or capacitance or inductance or all of them ? Or high frequency skin effects ?)
In any case you can use a suitable combination of lumped elements.
In addition, it may be helpful to examine some appropriate application notes in which the simulation model of a transmission line is explained.
I am sure that controlled sources are not the right way.
The wire is pretty much needed for coding reasons. I am implementing an 8*8 bit multiplier in HSpice. For the input,instead of giving it a pulse, I have decided to directly connect each bit to Vcc and gnd. Since there are a couple of test inputs, I thought the best thing would be to use a small resistor.
I know, it would be more reasonable to implement the multiplier in Verilog or VHDL, but it is the project instructions.
