应该就是没有，我试了各种软件都没有，比如Proteus8.9，Pspice 17.2

We do not currently have an available PSpice model for any CMOS monostable multivibrators (like the HC221). We recommend prototyping rather than simulation with this type of device. This is due to the nonlinearity factor (K) that is a function of the connected capacitor value. PSpice just plain out doesn't support modifying a model based on a passive connected to it. We have been working on a possible work around for a while, but it's unlikely that it would be available this year.
