hey everyone and thanks
i tried to make a cmos inverter and i need a simulation of a dcsweep
this is my circuit

[/url][/IMG]

and this is the messge i get

can someone help me and tell me what to do?
i get there is aproblem in vdd or vin or my c..but i dont get what is worng..

 

MBreakn=1 is invalid and should be the model name used for the mosfet.
It should be the same name used in the .model statement.

Also
Last number of the sweep directive is the increment.
Try changing DCsweep value to this:

.DC LIN V_Vin 0 5

BTW-
Some of the images you posted don't show up.

 

no..i made a new one..

I didnt get what to do..
u wanted me to change the value of the increment to 0.5?

 

No...the DC sweep was set to a value higher than VDD.

.set it the same or lower.

.DC LIN V_Vin 0 5 <---set this to five or less

 

why have you written Mbreakn=1, Mbreakp=1 ?
That is wrong notion.
Change it to simple Mbreakn , Mbreakp both in Model definition and on Capture Parts.
On capture parts see the property called IMPLEMENTATION. It's value should be same as model name, which is Mbreakn, Mbreakp in this case.
