I want to know the syntax of Parametric Sweep in Spectre language.

I need to add Parametric Sweep commonds in a spectre simulation file, but dont know how.

Does anybody know?. I mean do not use the simulation tool of Analog Design Enviroment, just insert the commonds into the spectre simulation file.

Thanks

Thanks, but I need more details.

For Example:

I want to change the voltage of signal Vctr from 0V to 1V with the step 100mV. At each voltage, I need to simulate the ckts 100ns.

How to write the code to achieve the above setting?

Many thanks

Well, reading the documentation (cdsdoc) would have allowed you to work this out for yourself.

For those unable to research simple things themselves, here's what you'd do:

Code:

// your circuit is here somewhere
// this source may already be in your circuit, but this
// is for illustration
vctr1 (Vctr 0) vsource dc=0

ctrsweep sweep dev=vctr1 param=dc start=0 stop=1 step=100m {
  tran1 tran stop=100n
}
