divide-by-zero

Hi,

I am new to PSPice and I need some advice.

I am trying to simulate a SN74LVC541A, a simple pulse input to see the delay.

However, it only works for VCC up to 2.99Vdc, 3.0Vdc and above gives me divide-by-zero in the simulation.

The nominal VCC for this device is specified 1.6 to 3.6 Vdc.

Would it be possible for you to share the design?

Hi,

For SN74LVC541A part, in simulation settings just enable the setting of SKIPBP (skip initial transinet bias point calculation) as shown below and check if it works and set the value of VCC ( in schematic design) to 3.6V.

Hope it works.

 

Regards

Ashish Gupta
