hi all

i would like to know which tool is better for behavioral modeling, for example, for PLL or CDR.

please also tell me whether you are in company or in university. i would like to know what people use in these two different areas.

i think the candidates are Matlab, simulink, ADS, verilog-a or AHDL, etc.

thank you.
 

I am in university.
In general, I work with the matlab and simulink.
in addition to, the systemC is a good solution

I am in company .We use verilog-a & Matlab

Click to expand...

do you use cmex or stateflow or just use the components in simulink itself?
are they enough?
for example, i want to model a VCO with phase noise, and i do not know how to model that with the components within simulink. i only find one VCO component, however, it does not have phase noise function.
 

I am using verilog-A and matlab
 

MATLAB SIMULINK & ADS, Both are used.
However Simulink is prefered.
working in company.
 

Verilog-A and simulink, University
Verilog-A is really nice. When you finish the behaviral simulation and start the transistor-level circuit design, the building blocks can be easily replaced from Verilog-A view to schematic view one by one to do the system simulation.
In verilog-A, jitter can also be simulated, which is shown in the attached paper.
 

Could simulink simulate the AC characteristic?
 

i use verilogA and simulink.(company)
 

I use the following tools:
MATLAB,SIMULINK,OrCAD,MULTISIM for analogue simulation.
 

Simulink is not very good at simulating electronic components. An add-on call the Simpower systems blockset is required for limited functionality.

Verilog-A provides a clear migration path to the IC level and is aware of the potential/flow (voltage/current). Also you can specify risetime, falltime, delay for every block.

I am neither at a university or at a company, but i am at peace.
and i use verilog-A. :D

Check out the design examples in the pllLib in cadence/spectre.

Also scour through the archives of the behavioral modeling conference.

i am in university
i use the ADS and Matlab.
i think the ADS is convenience and quickly, while Matlab is very professional.
 

use matlab, or verilog-A...
in Uniersity
 

I use verilog-A( with Spectra), but calculations using matlab. ASCII file is from tran simulation.
Industry
 

i m using Verilog-A with spectre
universty
Verilog-A in an analog design enviroment is very usefull and help in top down design flow
 

Matlab -> Simulink -> VHDL-AMS/VerilogA (Degree of abstraction and design performance)

Company
