So from the Analog Design Environment choose Analysis->Choose and select the dc option. Here select as sweep variable Temperature and then set the star value to -40 and stop value to 125. Set sweep type to linear and then step size to 5. The set the enable option. For the resistor part you'll have to define in the shematic R1 as a parameter. Then from ADE choose Tools-.Parametric Analysis. Here
set the variable name to r1 or whatever name you have given to the parameter and set the from to filelds to 10k and 20k respectively. Also set step controll to linear steps and give the step size 100. the select the parametric analysis. I know its much more complicated than it should be, but it does the trick. hope I was clear enougth.
It depends which simulator you choose.
If you choose spectre, DC sweep can sweep a variable R1, which is defined in the schematic as above-mentioned. Then use parameter analysis tool to sweep TEMPDC.
If you choose hspiceS, DC sweep can only sweep independent sources. In this case, you may use parameter analysis tool to sweep both R1 and TEMPDC. The analysis type can be empty (Neither DC, nor TRAN, nor AC analysis is enabled) to speed up the simulation -- This will only enable operating point analysis. To plot output waves, you may define output expressions as VDC("/out"), IDC("/M1/D"), etc.
Parameter sweeping by hspiceS in ADE is much slower than standalone hspice simulations because the former will re-netlist the circuit whenever a parameter changes its value.
Thank u all at first!
Now i have little difficult question.
Using the method cristianb said,i got a series of curves having Temp as X-axis and Voltage as Y-axis,each curve has a own Resistant.
But if i need the X-axis represent Resistant,Y-axis represent Voltage,each Temp have a own curve,what should i do?
