Use of "time" as argument

IPerino

In a very simple circuit I am not able to use "time" as an argument inside a Resistor value, nor Voltage source.

In fact, what I need is to simulate a frequency chirp up signal using transient simulation. I have seen it on LTspice it is very simple using behavioural voltage source but I am not successful at Capture / PSpice. Dealing with this issue, I tryed on a resistor value and I got:.

**** INCLUDING SCHEMATIC1.net ****
* source PRUEBACONORCAD166
R_R1         0 N14398  {time} TC=0,0

WARNING(ORPSIM-15215): TIME variable (S) not allowed in this context
-----------------------$
ERROR(ORPSIM-16318): Missing or invalid expression

Please I have seen on some forums I should be able to do this but after working around I havent found the way.

Thank you very much
