Is Pspice suitable for a timing simulation

Hi all,

I am a student, would like to design a Delay locked loop. Is Pspice able to help me in the simulation ?

1) Is Pspice suitable for a timing simulation?
2)Pspice can change the (process , voltage, temperature )PVT in the setting?
3) Does Pspice can add additional libraries in the tools?

or any simulation tools that able help me?

thanks .

helps in need...

warmest regards;

Hello,

Yes, pspice is suitable for timing simulation as it has a transient simulation option where you get results versus time. It solves the time domain equations that belongs to your circuit components.

For your special case, if you can convert what you want to a combination of circuit components and equations, you can do it. Pspice also enables entering (non) linear equations. You have also standard multiplier, differentiator, integrator, summer, polynomial description, etc. So instead of a circuit, you can also model functions based on these building blocks. It saves simulation time.

When your frequency of input signal is very large to 1/ (time constant) of your complete DLL, you have to simulate many RF cycles, hence the simulation can be very slow.

There are many vendors of pspice programs and they are not too expensive. Many vendors have evaluation or lite version.

I frequently use beige bag pspice for lots of things, also not electronics related.

Several semiconductor models have temperature behavior in it. Of course the supplier of the models should use correct parameters and there it goes wrong sometimes.

Many manufacturers of components also provide pspice libraries.
When you buy a spice program from a relative small SW company, you somtimes have to make own conversions for importing the labraries into your spice environment.
