'Missing subcircuit' when creating a Pspice library part from the OPA188 Spice file provided by TI


I created a Pspice part using the Spice file provided by TI. When simulating, I get the following error:


ERROR(ORPSIM-15108): Subcircuit RNOISE_FREE_0 used by X_U1.XR101 is undefined ERROR(ORPSIM-15108): Subcircuit RNOISE_FREE_0 used by X_U1.XR105 is undefined ERROR(ORPSIM-15108): Subcircuit RNOISE_FREE_2 used by X_U1.XR104 is undefined ERROR(ORPSIM-15108): Subcircuit RNOISE_FREE_0 used by X_U1.XR103 is undefined


Some of the lines with the offending subcircuits are as follows:


XR109_3 23 9 RNOISE_FREE_0 XR109_4 41 9 RNOISE_FREE_0


Would 'RNOISE_FREE...' be circuits recognized by TINA (TI's software) but not by PSPICE? Could I replace them with an equivalent?



Thanks!

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
