I use calibre + hspice as post-simulation tool.
I got post-sim netlist by calibre , it is as :
.subckt ana_top VSSA VDDA GND18: 7 VDD18: 9 10 11 12 ......
But in this file and attached .pex and .pxi file, I found all pins except GND18 and VDD18 .
Since I have to do co-simulation with HSIM, I make a very simple netlist as :
global 0 vdd!
XI4 (vinvin vout) invv
C0 (vinvin 0 ) capacitor c=1p
R0 (vdd! vinvin) resistor r=100K
V0 (vdd! 0 ) vosource type=pulse val0=0 val1=1.8 period=1u width=500n...
Hi all, please tell me how to model cat5 cable in 100/1000M ethernet PHY transmitter simulation , I am pullzed in this for several months.
IEEE 802.3 only gives 10M cable model , but it doesnot fit for 100/1000M.
Thank you in advance!
According to University of New Hampshire's relevant documents and IEEE 802.3 standard, I found a lot of specs to simulate. Can anyone give me the guidance how to set up the simulation environment in candence? Thank you very much!
For a normal current source , we first have a current , then the current flows through a dioded connected mos and generates a voltage vx, so vx makes M0 generate a current.
But for a wilson current mirror, how does it generates vy and vz ? Only formula
forces these two nodes to be the correct...
Thank for your reply.
Can you tell me why SR>2*pi*f*V(peak)?
Let us turn to this problem. If we look the schematic as a two stage opamp, the first stage SR is Ibias/C, while the second is Itail/Cout. How can he calculate the formula 1?
Can someone tell me ? thanks !
Hi all, I am using spectreVerilog to take a mixed-signal simulation.
But when I ran transient sim, the error comes out in the log as in the picture, it says :"component name (vnex5 and vnex5 ) not declared"; and
the netlist writing the vnex5 and vnex5 is in the picture too.
Does anybody know...
