ERROR -- Subcircuit TWA used by X_U1 is undefined


orcad10.5 的解决办法如下:但是我试过多次都未解决???
Subcircuit used by is undefined

The identified subcircuit is not defined in either the circuit file or any of the referenced libraries.

Solution

1 Check for correct spelling of the model name.

2 If necessary, add the name of the library in which it can be found.
