Hi,
I used Vpwl function from PSPICE library to generate exponential wave. But in that maximum of only 10 samples I could have, and I don't get a smooth curve.

So can anyone tell me how to generate a smooth exponential curve in PSPICE?

If I generate exponential wave in stimulus editor, how to map it to PSPICE to use it as some exponential source?

Can we generate exp wave using EVALUE? If so how to generate?
 

There should be an exponential pulse you could use:

Vxxx n+ n- EXP <(> v1 v2 <td1 <t1 <td2 <t2>>>> <)>

Have a look in your Pspice help or manual.

Keith.
 

You can follow the method suggested by Keith. You can also use the EVALUE for same. To use evalue you can directly use the expression (output voltage ad function of time) and output voltage of E source would be as per expression.
Refer the Voltage-controlled voltage source in PSpice Reference Guide
