Data not saved in a raw file?
Hello - Last Thursday a simulation consisting of a 100 x 100 grid of resistors and capacitors was started.? I knew this was going to take a long time (transient response) and arranged for use of a

Re: Regardinfd Delay Element simulation
Other than that, all are fine??please confirm.. shall i give clock signal for the nodes VIN_P, VIN_N, and VBIAS_P?? please confirm. Thank you

Re: Regardinfd Delay Element simulation
You left unconnected signal pins. Look at nodes VIN_P, VIN_N, and VBIAS_P. Why do you have nothing connected to these pins?

Re: SPICE Error
Ian, With respect, we don't know for sure where the circuit should be grounded, as we don't know what the application is. Perhaps the rectified bit should be floating? Regards, Tony

Re: Frequency
Hello AG, You could make an FFT of the signal or you use .MEASURE commands. Please take a look to the examples. Files > Tut > MEASURE > TRAN Best regards, Helmut

Re: How to make AC voltage source symbol with a sine wave shape
The symbol is just a symbol ... an icon. You can draw it any way you want. It makes no difference whatsoever to the simulation. You could go into the symbol editor and change it to anything you like.

Re: How to make AC voltage source symbol with a sine wave shape
It looks like some body modified the symbol for a voltage source. If you control + right click on the voltage symbol you get the "Component Attribute Editor" dialog. In the upper left corner Click on
