This might be silly question but i want a clarity on it .
i used circuit wizard to create Pcb layout of electric circuit . every circuit has one ground . either we could use one ground icon function and connect all required points to there . but i tried to add new ground icons every where required .
and i converted into pcb layout . i doubt all the grounds are connected to same point or not ??
Please make a jpeg image of your schematic and post it. Maybe open the project to the schematic page, capture a print screen, paste that into Paint and save it as a jpeg. We need to see the circuit, or have you explain it fully, to be able to tell you.
As to your question about "grounds," there are various types and there are various misuses of the term "ground." It's going to take some reading on your part to fully understand the subject, but here are some (v-e-r-y limited) pointers...
- There is circuit ground. This is the ground that the circuit uses.
- There is earth ground. As a limited explanation, this is the common grounding that is tied to the buildings ground to the dirt outside. You need to be careful what types of circuits you tie to it, because you are making circuits have a common connection point. Often, this can be hazardous.
- You know of the positive voltage side of a circuit. But, many circuits have and use a negative voltage supply. This negative supply is not ground.
Once we have the schematic and get you sorted out on the type of "ground" you mean, we can try to help you with the Circuit Wizard program to get the ground function working as you intend. I have not used that particular program, but there is commonality with the PCB programs and we might be able to help you, anyway.
If you are just starting to learn Circuit Wizard, you may want to use your energy to learn KiCad, instead. It is a free program, rather powerful, well supported and used widely. You won't have any trouble finding others to help you to get it to work.
