I am using Encounter Library Characterizer to generate .lib file from a custom cell that I have made myself.
I use QRC to extract the RLCK parameters of the cell.
But when I put the spice netlist as the input of Encounter Library Characterizer,
it does not recognize the mutual inductance at...
I am Teraze. In my design, I need to consider the self inductance and mutual inductance of transmission line. First, I use plain wire for transmission line in my layout. But when I do parasitic extraction, I found that I cannot extract the inductance.
Then I use a cell named coupledcpw from...
I want to use StarRCXT to extract the inductance on a piece of transmission line.
But when I write "EXTRACTION: RLC" in the cmd file and run with it.
StarRCXT gives out an error of :Inductance extraction is not supported in this release.
Could anybody tell me that how can I extract...
I want to do a transient simulate with such a condition:
One part of the whole circuit is with higher temperature than the other parts of the whole circuit.
.TEMP only defines the chip temperature
I searched on the HSPICE manual, and find this syntax:
xi1 net1 net2 subckt_name DTEMP=+20...
I am using HFSS to simulate the skin effect of a transmission line segment.
I need to increase the number of mesh in order to get the right result.
I try to increase the minimum converged times, this does help to increase the number of mesh.
But it is really time consuming and it needs to...
I am doing a 3D simulation on a transmission line segment in HFSS.
I want to enlarge the number of tetrahedrons so as to solve inside the transmission line segment.
Is the number of tetrahedron can be specified by user before running a simulation?
I wrote some
.measure statements in my hspice netlist.
But for some reason the .mt file does not generate properly.
I have the .tr file generated properly, can I use the .tr file to regenerate my .mt file?
I don't want to rerun the simulation, it is too time consuming.
I am using HSPICE for simulation.
I have a transmission line segment in my design.
I want to test the impedance variation of this piece of transmission line vs. frequency.
So I want to do a frequency sweep to get the impedance of this tline for each frequency.
I search online and find I...
I try to simulation the current density of a metal strip at high frequencies.
So I am now doing simulation in HFSS with a frequency sweep.
After the simulation is done, I tried the HFSS=> fields=> plot fields=>J=> MagJsurf.
But it turns out to be:
Plot Mag_Jsurf becomes invalid due to no...
I am now using the transmission line model in Hspice to facilitate my design.
the U element is the lumped RLC transmission line model.
and W element is the distributed RLC transmission line model.
The simulation are quite different between these two models.
I have no idea how these two...
I am totally new to soc encounter.
I finish synthesis in Design Compiler,
Now I am using soc encounter to do the place and routing of my design.
When I import the design, a sdc file is needed.
Could anyone tell me which tool generate this file?
Yes, please. I don't know anything about the lef file.
Actually, I want the lef file for the standard cell that I have written in my Verilog file.
I assume this lef file is used for mapping, I am not sure...
I am totally new to soc encounter.
I want to import a design to encounter, a lef file is required.
There are several lef files in my design kit and I don't know which is the right one.
Can anybody sent me a sample of a lef file?
Another question is: Can the lef file be used both by cadence...
I am just begin to learn power amplifier design.
And I need to design a high gain power amplifier with center frequency of 10GHz.
and S11, S22 below-20dB。
Can anyone give me some hint on how to start with the design?
I have a problem here:
I did my custom layout design in cadence. Then I stream out the GDSII file and import it to synopsys. Then I generate the CEL view and FRAM from it.
Now I need a .lib file which contains the area information of my custom layout.
Could any one tell me how to generate...
Thank you for your design.
But what I want is dB(S(1,1))<=-20dB. @1.5GHz<=f<=2.5GHz
I have two questions:
how can you have such a flat passband?
I remember if chebyshev filter only provide a equal ripple passband。
The schematic looks as the plot in the attachment:
A impedance matching network is required for matching the output impedance.
The output impedance is a series RL, in which R=15ohmu, l=7.95nH.
The source impedance is 50ohmu.
The goal is :
