charge pump model for HSIM simulation?

[yangyukuo]

Hi:

If I've got the load-line (output voltage - output current) of a charge pump circuit, how can I use the parameters in HSIM simulation without using real charge pump circuit?
For example,
output voltage=7v, output current=200uA
output voltage=6v, output current=250uA

Thank you

Ken

Use a VCCS (G-element) with a PWL source, something like

G_chg_pmp 1 0 PWL(1) 2 0  7V,200uA  6V,250uA  ..,.....
