Hi Everybody
I have Designed level shifter(5V→3V) below
I did the simulation and I completed the circuit

However, after copying this circuit and pasting it on another page on Orcad, we simulate the following error.
---------------/ OrCAD Error Output/-------------------

**** RESUMING S.cir ****
.END
ERROR(ORPSIM-15141): Less than 2 connections at node 5V.
-------------------------------------------------------------------------------
So I connected two 20k in parallel to the R17 It will eventually reach 10k.
So it's a simulation.
However, the value is completely different from the previous simulation
What do you suggest?
Thanks
