RF Design Flow/Methodology

Hi,
How is the RF design flow and methodology different from other analog design flow? I know somewhere along the line, the EM simulation may be involved, but aside from that, what is the major difference from other analog designs, starting from schematic entry, circuit simulation, layout, rc extraction, back annotation, DRC/LVS, etc.,

1. Do I miss any step in this design flow described above?
2. In each step, what is the major difference for analog and RF designs?
3. When do I need to run EMI and for what reason?

Any reference materials for me to learn more?

Thanks in advance!

Hi..ur steps are correct but while creating the design you should have to take care..
RF boards are high speed boards where frequency is more then 80 MHz.. analog signals are more noise then digital..so while making the design you have to keep this is mind..RF signals flows with high speed on the PCB.which will create the electro magnetic interference . which will causes other device disturbed . while routing shilled your RF signal and use more number of stitching via in RF section which is helpful to remove the noise..You can analyze the EMI effect after your routing.,It has many tool to analyze .

EM analysis is required if you have custom components where no models exist, e.g. inductors or transformers optimized for your specific needs (max Q at target frequency).
The on-chip inductors from the library are often a compromise because they might be designed for the wrong frequency, so that they do not give the best electrical performance for the given chip area. Customized inductors can save chip space and/or give better performance. To calculate their electrical model, you need EM analysis.
