Figure: Example PSpice circuit.
All PSpice programs should contain the following: a heading, this should be the first line
of the program; a `.end' line which should be the very last line of the program. Between
these two lines there should be commands to specify the circuit which is to be analyzed.
To specify a circuit, first label the nodes in the circuit (see Figure 
)
with node 0 always being
the ground node. Once your circuit is labeled, enter each element in the circuit as follows:
value
value
value
, 
, and 
are names of the elements which should begin
with V, I and R respectively. Examples include V1, I12, R1 and VDUMMY. Only
the first letter is important.
To completely specify our example circuit we would write the following code:
Example Circuit 1 V1 1 0 5 R1 1 2 5k R2 2 0 1000 .tran 0.02 2.0 .probe .end
To evaluate your PSpice code, type it into a file ending with a .cir suffix (eg.spice1.cir). Type the command pspice. When prompted, enter the filename you chose. After PSpice has finished running, type the command probe.
