SN74LVC1G125: PSpice model error: Values must be monotonic increasing

Lenio Cacula

Part Number: SN74LVC1G125

I have tried downloading the model from the product page and using the model available from within PSpice. In both cases the project doesn't complete the simulation and indicates the error "Values must be monotonic increasing". I tweaked everything I could in the circuit and the result is always the same. Other buffers run without issue. Can you provide some guidance to solve the issue? My ultimate goal is to estimate power dissipation in a specific configuration.

Hello,

Can you share your simulation file, or at least a schematic?

Thanks!

It looks like the model in PSpice for TI and on our website is a 2014 behavioral version -- we have a much better behavioral model in the works.

I'll work with my team to get that old model updated in the system. I'm not sure how long it will take to get from us to the web though, so I'll get you a netlist file, hopefully before the end of the day.
