hspice analysis problem

hi. How i can plot the output voltage curve represented by a variable resistance in transient Analysis with hspice? and my other question is that , Why, when I measure the capacitance value of vccap , its value is not shown? like this: .op .tran 2ns 1ms .probe Gcap 7 8 VCCAP PWL(1) 1 2 -1v, 0p 1v, 1p vi1 1 2 sin( 0 1 1k) .

How do I measure the input capacitance of an Inverter?

Dear all, I want measure the input capacitance of an inverter for the vinput range of 0 to 3.3 V I am following the approach mentoined below: 1. at the input of the inverter I connect a dc voltage in series with a ac source. 2. then I am doing a parametric analysis (sweeping the dc value from 0 to 3.3 V) under which I am doing an ac analy

How can i measure inverter input capacitance in Hspice simulation?

Hi everybody. Is there anyone how can guide me to measure input parasitic capacitance with hspice simulation? Thanks in advance. Alireza

hi please say to me that how I can measure the capacitance in drain of an inverter in "hspice" simulation? thanks

difference between capacitance in Hspice

Hi, everybody: What's the difference between capacitance parameter Cdg and Dgd in hspice? and how can i measure the capacitance between gate and ground(if bulk and sourse is connected) in hspice? THX!

How to simulate pharse margin v.s Cload in Hspice

Dear All How can I use Hspcie to simulate phase margin v.s. load capacitance Y axis is phase margin X axis is load capacitance I use .measure to get phase margin but I can't plot it on spice explore. Could you give me some hspice code to do this simulation? Thank you Added after 1 minutes: jus

Measure the output load capacitance using HSPICE

Dear All, does any one know how to use hspice to measure the output load capacitance of a circuit?

How can I generate a C-V plot of Psub/Nwell diode using HSPICE?

There is something called LX3 or LX1 statement from which you can measure the capacitances across a diode. Please refer the hspice manual.

is realy output of cap() function in hspice, capacitance?

is realy output of cap() function in hspice, capacitance? i need to measure capacitance between to nodes of circuit. do you have some idea?

Hspice and capacitance

i want to measure capacitance of a circuit with hspice. do you have some idea?

How to compute the power dissipation of i/o pad???

For simulation , you can use .measure command in hspice for calculating the power dissipation

How to plot the graph of the effective capacitance in Hspice

you can measure the effective capacitance between 2 nodes, by the capacitance define.

PFD delay for eliminating the charge pump dead zone

just measure the voltage on the capacitance and multiplied by C, that is the Q . you should add the .meas statemant in hspice list: .mear tran vcpo avg v(o) from=XXn to=XXn. .meas charge param='vcpo*C' where v(o) is the voltage on the capacitance . the plot is "charge stored in capacitor VS phase error" ,not (...)

How to calculate the input capacitance of I/O cell in Hspice

to measure the input capacitance you may drive the port with a current. So, by measuring the time it takes the signal to go between two different voltages you can deduce the input capacitance. I=C . dV/dt You must be sure that the parasitic capacitance due to interconects is considered and explicitly present in the (...)
