I have the CD4000 library for LTSpice kindly provided by Eric G. I can change the VDD say 5 volts or 9 volts in the attribute editor and all the thresholds and stuff change. Cool.
But if I want to depend on the thresholds during power up or down the Vdd needs to track the circuit supply voltage. Is there an easy way to do this?
