multiple .alter hspice
I'm using hspice 2008.09, windows version
my netlist contains 2 .alter before .end
According to the manual, I could split all the 3 cases in to 3 CPU by using -mp such as
hspice.exe -i netlist.sp -o -mp
BUT, the hspice window appears shortly and closes with nothing...
This style is used widely in many text books and thesises(see the attachment pic). Unfortunately, I'm not able to find such a software to create this kind of graphics. Can someone give me some advice about software information or some plugins.
Re: Differential VCO, Short or High Resistance at control po
Yes, in theory, it is short to gnd. But, in the measurement, the vctrl is given by a dc probe, which cannot be considered as an ideal "short" to ground. Then, my problem is the necessity of adding a decouple capacitor for the RED node
The frequency of this vco is controlled by the Vctrl at the RED point. I'm not sure whether this node should be short to ground or high resistance for the signal. That is to say whether to add a big capacitor to short it to ground or connect to a high resistor to Vctrl.
If a spiral inductor is improved to have a higher self resonant frequency (SRF), but remaining the inductance and Q factor, What will a circuit, e.g. VCO, benefit from it?
As in my knowledge, the performace of VCO is determined by Q-factor of inductor. The designers optimize the inductor to...
I've got rglc parameters of a multiconductor transmission line system. I'd like to use @ds to simulate the system based on these parameters, not calculate by ads itself. Can someone show me the steps or in @ds and the format of the rglc file. The @ds help doesn't describe it in detail.
I set the frequency range from 5G to 10G and operate the standard 1 port calibration (SOL), using the standard calibration kits.
I happened to see the strange display:
When I re-connect the "open" calibration kit I used before, the display is not a point or even a short line around the open...
GP-------------GP
SP-----@------SP
GP-------------GP
GP: Ground Pad
SP: Signal Pad
@: spiral inductor
The other questions are:
1. Do I need to connect two ground pads under the signal pad on each side?
2. Do I need to draw "open" "short" "through" and "load" for calibration?
dt is constrained by the spacial grids and satisfied with stable condition.
t is the time when gauss pulse reaches to the peak. The greater of t, the more flat of exciting fields from the start time. I mean, the E(y) is start from zero,not suddenly reach a high value.
You can try to simulate the...
The voltage and current you mentioned are the values at one time spot. Calculate V and I at every time on your concerned place.
Now you've got the voltages and currents at every time steps. i.e. you got v(t) and i(t), where t=n*deltaT. deltaT is time step. n=0,1,2,...
Then V(f)=FFT(v(t)) and...
