Hi

I am trying to have 3 voltage sources in my testbench:

vsource #(.type("sine"),.dc(0),.freq(5000),.ampl(5)) vin1(vinp,vss);
vsource #(.type("dc"),.val(2.5)) vin2(vinm,vss);
vsource #(.type("dc"),.val(5)) vin3(vdd);

Now is this a proper definition for a DC source?Am I allowed to have such multiple definitions in a single test bench(they are for the Positive,Negative and High Voltage State terminals of an op-amp with vss being grounded)

what parameters should I specify for a dc source?
