Can you please suggest me some forums to clear this doubt? Please.

How to calculate dynamic power of an inverter in hspice? Please help I am stucked here. Please help me with an example.

Thanks Holger, now C1 is sweeping perfectly. But When I am putting a capacitance value (let say C1 = 1.1fF) without while loop, then I am getting little bit variation in avg_delay value when capacitance C1 is 1.1fF with while loop, Why is it so?

Can anyone please tell me how can I sweep capacitance(C1) in order to measure different delays for different capacitance for this netlist. Netlist ************Ngspice Transient analysis********** .include cmos_22nm.txt ***********Parameter definitions*************************** .param temp = 25 .param pvdd = 0.8 .param lmin='22n' .param wmin='22n' *****************Netlist******************************** VDD net1 GND pvdd Mp1 nodez nodea net1 net1 pmos W='2*wmin' L=lmin Mn1 nodez nodea GND GND nmos...

Yeah, that worked but for this netlist I am getting the same avg-delay which is 2.49 picosecond and the Capacitance(C1) at nodez(output) of the inverter is not changing and I am getting the same capacitance(C1) because of that I am getting the same avg-delay. Can you please take a look at how to sweep that capacitance C1 in that while Loop between .control ... .endc ?

Ok, I tried to run the script inside the .control ..... .endc as below for a single capacitor but getting the error can you please take a look at it.
