TPSM82913: Pspice model problem

Ananth Y R

Part Number: TPSM82913
Other Parts Discussed in Thread: TPSM828301

Tool/software:

I am designing a power circuit using the TPSM89213 and TPSM828301. The startup transient simulation works when Individually simulating the modules. Upon combining the modules into a single circuit, the following errors show up.

ERROR(ORPSIM-15461): Incorrect number of interface nodes for X_U3.X_U9_U1_U4

ERROR(ORPSIM-15461): Incorrect number of interface nodes for X_U3.X_S-CONFIG_U11.

The circuit is similar to the example circuit provided from TI, except for the S_CONFIG connected to VIN.

Kindly help resolve this
