Invalid Subckt Definition

Hi, I am using mutltisim 11 and I wanted to create a schematic symbol for LM386 low volatge audio power amplifier. I was able to create the schmatic, but when I run the simulation this message appears: ------ Checking SPICE netlist for LM386_VoltageGain_10 - Thursday, March 22, 2012, 3:19:02 PM ------
SPICE Netlist Error in schematic RefDes 'u1', element 'xu1':  Invalid subckt definition name 'u1_open_gain8'
SPICE Netlist Error in schematic RefDes 'u1', element '<unknown>':  Due to errors, the subckt instance 'xu1' has been omitted from the simulation
======= SPICE Netlist check completed, 2 error(s), 0 warning(s) =======

 

Any suggestions??....I'm new to using multisim

Hi,

 

I took a look at your circuit and it seems that you did not add a spice model for the component. You need a spice model to create a simulation component. You need to re-create the component. Follow the instructions in the link below:

Hope this helps.
