9. Electrical Integrity Analysis
The following electrical analysis are
carried out in the pre and post layout analysis:
Signal Integrity Analysis
Timing Analysis
Power Integrity Analysis
S-parameter Analysis
The test boards operating at high
frequency and fast switching rates demand
SI analysis for the right design for first pass
success. Our SI engineers are having strong
knowledge in SI theory and expertise in
simulation tools to analyze various SI issues.

Controlled Impedance Calculation
The Trace Width is calculated for Single ended signals and Trace
Width/Spacing for Differential Pairs to achieve controlled impedance of
50 ohms & 100 ohms respectively

15. 15
Insertion and Return Loss Calculation
The trace is modeled with a ground coupled via
Insertion loss @ 800 MHz = -0.787 dB (up to -1dB is good value)
Return loss @ 800 MHz = -16.003 dB (below -15dB is good value)

16. 16
Interconnect Bandwidth verification
The band width (BW) of the interconnect is calculated
BW = 0.35/RT (This is thump rule from signal integrity theory)
RT = rise time for 10% to 90% signal level
RT =197 ps
BW = 0.35 / 197 ps
= 1.77 GHz

Reflection Analysis
The receiver waveform is not
crossing the threshold levels and
not good
