I am trying to build the following circuit in PSPICE for a university assignment
My input file is currently:
COMMON EMITTER AMPLIFIER
*
Vin 1 2 0V
R1 1 4 56k
R2 1 2 22k
RB 1 3 180
RC 4 5 5.1k
RE 7 8 3.3k
Q1 6 3 7 QBC337-25

* General purpose NPN transistor
* IC = 500 mA
* VCEO = 45 V
* hFE = 160 - 400 @ 1V/100mA
*

I am getting these errors.
ERROR -- Less than 2 connections at node 5
ERROR -- Less than 2 connections at node 8
ERROR -- Less than 2 connections at node 6
ERROR -- Node 1 is floating
ERROR -- Node 2 is floating
ERROR -- Node 4 is floating
ERROR -- Node 3 is floating
