I'm using Pspice to design a regulated power supply and I'm getting the following error when I run my simulation:
ERROR -- Subcircuit TX used by X_TX1 is undefined
does anyone no what causes this type of error. I'm using a transformer from a library called SEDRA_lib which is part of Microelectronics textbook
My circuit consist of the following: VSIN - R1 (.5ohm) - primary windings all in series - GND
Secondary side of transformer:
Ls1 - D1 - C1 - R2 - Zener - Rload - GND Center tap - node w/C1 -zener- R3 -R4 - GND Ls2 - D2 - node w/D1 -C1
I would appreciate any assistance
