Here is my first pass at the HC4046 (VCO portion only), now in LTspice

Looks pretty good to me, apart from LTspice not understanding "IS" parameter.
Sometimes LTspice throws up over what it's supposed to know... IS is a
common parameter for MOS devices... defines the body diode.
Plot of frequency versus control voltage attached
Looks good.

I love to cook with wine. Sometimes I even put it in the food.
