## how to print node-to-node capacitance?

I'm trying to find a way in spectre to calculate the capacitance between every two terminals of a transistor (I hope it exists). In spectre users' Guide, info could be used to print node-to-node capacitance. (...)

## Measuring Node Capacitance

i think you can get the summary of parasitic capacitance at each node after doing layout parasitic extraction

## Regarding Node capacitance in spectre

Hi, all. In spectre, we can get the node capacitance of the circuit. But these node caps only include the gate caps, excluding the junction caps. Does anybody know how to get the junction caps in spectre? i am not meaning just one transitor, I mean the node connected to every relevant (...)

## how to print node capacitor in spectre?

I had done a function request to Smash some years ago to implement the printing of node capacitance and node impedance. These infos are side effects of the modified nodal analysis but still not used in simulators. I need it some years ago for detection of floating nodes in analog circuit. I know that for digital TL there (...)

## how to get the node capacitance and resistance using spectre

I heard you got the node capacitance and resistance using cadence spectre simulation. But I donot know which option. Can anyone tell me .Thank you

## How to find out the total node capacitance during DC simulation using Spectre?

hi, is there a straight forward way in spectre to find out the total node cpacitance on a certain node during dc simulation ?

## ploting capacitance vs node voltage

hey guys i want to plot capacitance on x axis through parameter sweep and voltage at a node on y axis.when i do performance analysis then i don't get voltage as an allowed variable.and without performance analysis i dont get capacitance on x axis. how can i do it? pls help soon if possible. thanx in advance a lot.

## Difference in Algorithms used

spectre works on Transient Imbalance (change in the node voltages)algorithms while SPICE works on capacitance charging and discharging algorithms. The methods are more or less similar in both.

## One question of hspice/spectre simulation?

In HSPICE you can define the capacitance of a capacitor with an equation. For example: Csensor node1 node2 c='5p*v(controlvoltage)' CTYPE=1 This will make your capacitor depend on the voltage at the node "controlvoltage". If this voltage is defined to be 1V from 0s to 500us, 2V from 500us to 1ms and back to 1V at 1ms, (...)
